Erinome:Hello dear friends, welcome to our podcast! Today, Enceladus and I are going to talk about a cool topic—why sea water doesn't freeze easily. Have you ever thought about that, Enceladus?  

Enceladus:Um, yeah! Like in winter, lakes and rivers on land freeze, but the sea often stays unfrozen. Why is that?  

Erinome:Let’s start with the basics first. Do you know what "sea ice" is?  

Enceladus:Is it just ice from the sea?  

Erinome:Kind of! Sea ice is mainly saltwater ice formed when seawater freezes directly. Oh, and in a broad sense, it also includes river ice and icebergs in the ocean. Cool, right?  

Enceladus:Wow! So there are different types of sea ice?  

Erinome:Yes! Two main types: fixed ice and drift ice. Fixed ice is frozen to coasts, islands, or the seabed—it moves up and down with the sea level. Drift ice floats on the surface and moves with wind and ocean currents.  

Enceladus:Drift ice sounds dangerous for ships, maybe?  

Erinome:You’re right! The news said drift ice can affect ships and harm海上 buildings. But let’s get back—why is sea water hard to freeze?  

Enceladus:Is it because of salt? I remember fresh water freezes at 0℃.  

Erinome:Bingo! Sea water has a lot of salt. The average salt content is about 34.48‰. So its freezing point is lower than fresh water.  

Enceladus:How much lower?  

Erinome:Around -1.9℃! So even if the temperature is 0℃, sea water won’t freeze. It needs to be much colder.  

Enceladus:Oh! That’s a big difference. So salt makes the freezing point drop?  

Erinome:Exactly! And there’s another reason: sea water is always moving. Wind, temperature differences, and density make it flow, so ice can’t form easily.  

Enceladus:Like, the water keeps moving, so the cold can’t make it freeze quickly?  

Erinome:Yes! Unlike a still pond, the sea is always "dancing"—hard to freeze. But here’s some sad news: sea ice is getting less because of global warming.  

Enceladus:Oh no! Really?  

Erinome:Yeah. From 1981 to 2010, Arctic sea ice area decreased at least 13.1% every 10 years. That’s a lot!  

Enceladus:What about Antarctica?  

Erinome:Even worse. From 2014 to 2017, Antarctica lost over 2 million square kilometers of sea ice—bigger than Mexico! And it’s melting faster than the Arctic.  

Enceladus:That’s so sad… Why does this matter?  

Erinome:Sea ice is important! It reflects 50% to 70% of sunlight back to space, keeping Earth cool. But when it melts, the water absorbs heat instead.  

Enceladus:Oh! So more melting means more heat, which makes more ice melt? A bad cycle?  

Erinome:Exactly! And it hurts animals. Polar bears in the Arctic lose their ice homes, penguins in Antarctica too. Also birds, whales, seals… the whole food chain is in danger.  

Enceladus:Wow, that’s serious. What can we do to help?  

Erinome:Small things! Save water and electricity—turn off lights when leaving a room, don’t waste water. Green出行 like walking or biking instead of driving.  

Enceladus:Oh, and don’t litter! And use fewer disposable things, like一次性筷子.  

Erinome:Yes! Every little action helps slow global warming and protect sea ice.  

Enceladus:I never thought sea ice was so important. Now I know why we need to care.  

Erinome:Me too! It’s not just ice—it’s home for many creatures and keeps our planet balanced.  

Enceladus:So remember, friends: save energy, reduce waste, and protect our sea ice.  

Erinome:Okay, that's it for today. Let's all do our part to keep the sea and its ice safe. See you next time! Bye!  

Enceladus:Bye!

Erinome: Hello dear friends, today we are going to talk about "What's the most effective way to remove formaldehyde at home? Did you choose the right one?" I'm Erinome.  

Enceladus: And I'm Enceladus. Oh, formaldehyde! That's a big problem for people who just moved into new houses, right?  

Erinome: Exactly! My neighbor just decorated her house, and she's so worried. She tried putting pineapples and orange peels everywhere. Does that work?  

Enceladus: Hmm, I thought that was a common trick! But wait, I read somewhere it might not be true.  

Erinome: Oh yeah! A professor said those fruits don't remove formaldehyde. They just cover the smell with their own sweet scent. Worse, the fruit might make the room warmer, so more formaldehyde comes out! Oh no!  

Enceladus: Wow, that's scary! So what is formaldehyde, actually? Why is it in our houses?  

Erinome: A chemistry professor explained it's a harmful chemical. Like, formalin—you know, the liquid used to keep dead bodies from rotting? Formaldehyde is in that! It hurts our cells by changing proteins in our bodies.  

Enceladus: Oh no! So how does it get into new houses then?  

Erinome: It's from the wood boards! Like particle boards or fiber boards. They use a cheap glue called urea-formaldehyde resin. It's strong and cheap, so 90% of wood boards use it. But the glue releases formaldehyde for 3 to 15 years!  

Enceladus: 3 to 15 years? That's a long time! Why don't they use better materials?  

Erinome: The professor said there are better环保 (huanbao, environmentally friendly) materials, but they are expensive. So factories still use the cheap glue. Haha, he even joked the boards don't get bugs because formaldehyde kills eggs!  

Enceladus: That's dark humor! So what methods actually work to remove it? Let's start with the most common one: opening windows.  

Erinome: Oh right! Ventilation is simple and effective. It lets fresh air take the formaldehyde out. But the problem is, formaldehyde takes years to stop releasing. So leaving the house empty for 3 years isn't possible for most people.  

Enceladus: Yeah, no one wants to wait that long. What about activated carbon? I see many people buy those black bags.  

Erinome: A teacher from Nankai University said it works at first. Because carbon has small holes that can "catch" formaldehyde. But the holes are too big, so the effect is limited. And you can't reuse it by sunning!  

Enceladus: Really? The ads say "sun it and use again"!  

Erinome: The teacher said sunlight is only about 50°C. It can't make the formaldehyde in the carbon go away. So after 3 months, the carbon stops working. Those ads that say "92.9% removed in 6 hours" are lying!  

Enceladus: Oh no! So activated carbon isn't a magic solution. What about plants? Like spider plants or peace lilies. I heard they absorb甲醛 (jiaquan, formaldehyde).  

Erinome: They do, but very little. Let's see: a 100㎡ room with 0.2mg/m³ formaldehyde. A spider plant absorbs 20 micrograms per hour. To lower it to safe levels, you need 1800 pots! You can't fit that in a house!  

Enceladus: Wow, that's impossible. So plants are just a little help, not the main way. What about those sprays called formaldehyde removers?  

Erinome: Some are strong oxidizers. They can change formaldehyde into other chemicals, but those might still be harmful. And the spray can't go into the wood boards—they're pressed so tight, with a surface layer. So it only works on the surface, not the source.  

Enceladus: Oh right, the formaldehyde is inside the boards, not just in the air. What about photocatalysts? I saw them online, said to be super effective.  

Erinome: The theory is good! They need UV light to break down formaldehyde. But in rooms, there's not enough UV, especially in drawers or behind cabinets. So they can't work well there.  

Enceladus: So many methods are not useful! What about water or vinegar? I heard people put bowls of water around.  

Erinome: Formaldehyde dissolves in water, but a bowl of water has a small surface area. A small bag of activated carbon has more surface area than 100 bowls of water! And water makes the air more humid, which makes more formaldehyde come out. Oh no, that's worse!  

Enceladus: So all those "home tricks" are mostly useless. What's actually effective then?  

Erinome: The professor said the best methods are: first, ventilation—keep windows open as much as possible. Second, some special adsorbents like Maya Blue (a稀土-based material, with tiny holes to catch formaldehyde). Third, air purifiers with good filters.  

Enceladus: Maya Blue? Is that better than activated carbon?  

Erinome: Yes! It has smaller pores and more surface area. But it's more expensive. And the most important thing is to choose good materials when decorating—use环保 (huanbao) wood boards without formaldehyde. Prevention is better than cure!  

Enceladus: That makes sense. So the key is: don't believe the fruit peels or air fresheners—they just cover smells. 

Erinome: Hello dear friends, today we are going to talk about some important news about Tiananmen Square and the Palace Museum. Enceladus, have you seen the latest notices?

Enceladus: Oh, no, I haven't. What's happening? Is there something special?

Erinome: Yes! There are some closure notices. Let's start with Tiananmen Square first. Do you know when it will be closed?

Enceladus: Um, I have no idea. When exactly?

Erinome: From September 1st to 3rd. So three days. The notice says it's to make sure a special event can go smoothly and safely.

Enceladus: Oh right, special events need good safety. So when will it open again?

Erinome: It will resume opening on September 4th. But the notice says "适时恢复", which means maybe not exactly the early morning, but sometime on the 4th.

Enceladus: I see. So tourists who planned to visit Tiananmen Square during those three days can't go, right?

Erinome: Exactly. They need to adjust their travel plans in advance. The notice asks everyone to understand and cooperate.

Enceladus: That makes sense. Safety first, after all. What about the Palace Museum? I heard it's also closed?

Erinome: Yes! The Palace Museum has a closure notice too, but the dates are different. Wanna guess when?

Enceladus: Maybe the same as Tiananmen Square? September 1st to 3rd?

Erinome: No, not exactly. It's closed from August 31st to September 4th. That's five days!

Enceladus: Oh, longer than Tiananmen Square. Why is that?

Erinome: The notice says it's to "配合" (peihe) the Tiananmen area's event arrangements. You know, they are near each other, so maybe related.

Enceladus: Oh right, they are close. So when does the Palace Museum open again?

Erinome: September 5th. It will open normally on that day.

Enceladus: So if someone already planned a trip and needs help, what can they do?

Erinome: Good question! The Palace Museum provided a service hotline. The number is 400-950-1925. They can call for help.

Enceladus: That's helpful. I bet some tourists will be sad, though. Like, if they booked tickets or hotels for those days.

Erinome: Yeah, it's a little sad for them. But the special event must be important, and safety is the most important thing, right?

Enceladus: Totally. Better to be safe than sorry. By the way, when were these notices released?

Erinome: Both notices came out on August 24th. So people have about a week to adjust their plans. That's good, not too late.

Enceladus: Oh, that's nice. So no one will be surprised at the last minute.

Erinome: Exactly. Let me repeat the key dates to make sure. Tiananmen Square: closed September 1st to 3rd, resumes September 4th. Palace Museum: closed August 31st to September 4th, resumes September 5th. Got it?

Enceladus: Got it! So if I planned to visit the Palace Museum on August 31st, I can't go. But Tiananmen Square is still open that day, right?

Erinome: Yes! Because Tiananmen Square closes from September 1st, so August 31st is still open. But the Palace Museum is closed on August 31st. Don't mix them up!

Enceladus: Oh, that's a key point. People need to check each place's dates carefully.

Erinome: For sure. And remember, if you need help with the Palace Museum, call 400-950-1925.

Enceladus: Sad for the tourists who wanted to go, but it's for a special event. Hope the event goes well!

Erinome: Me too! Okay, everyone, please share this news with friends who might travel to Beijing. Adjust your plans and stay safe.

Enceladus: Yep! That's all for today. Thanks for sharing, Erinome.

Erinome: You're welcome! Okay, that's it for today. Let's talk again next time. Bye!

Enceladus: Bye!

Erinome:Hello dear friends, today we are going to talk about a big news in China’s car industry—Dongfeng Motor, a famous state-owned car company, is delisting from Hong Kong stock market and going private. Enceladus, have you heard about this?

Enceladus:Wow, really? Dongfeng is one of the "big three" state-owned car groups, right? I thought listed companies usually want to stay on the market. Why would they leave on purpose?

Erinome:That’s exactly what everyone is asking! You know, in China’s capital market history, central state-owned enterprises (SOEs) almost never do "voluntary delisting"—most delist because they’re in trouble. But Dongfeng is different. It’s like a bold new move!

Enceladus:So… delisting can be "voluntary"? I thought companies only delist when they’re failing.

Erinome:Oh no, there are two types! One is "involuntary delisting"—when business is bad, can’t meet listing rules. The other is "voluntary"—the company is okay, but the market values it too low, so listing isn’t useful for raising money. Dongfeng is definitely the second one!

Enceladus:Low valuation? How bad is it?

Erinome:Let me show you the numbers. In July, Dongfeng’s Hong Kong stock price was only 3.4 Hong Kong dollars per share. Its PB ratio—you know, price-to-book ratio, which is market value divided by net assets—was 0.16. Even before the stock stopped trading on August 8th, the price doubled to 6 Hong Kong dollars, but PB was still only 0.3!

Enceladus:0.3? What’s normal?

Erinome:Normally, a healthy company’s PB is more than 1. If it’s below 1, the market thinks its assets can’t make money in the future. Like, if Dongfeng has 10 billion net assets, the market only says it’s worth 3 billion. That’s super low!

Enceladus:Is this only Dongfeng?

Erinome:No, most global fuel car companies are in this "valuation winter". Their PB ratios are often 0.1-0.2. But new energy car companies? Oh, their average PB is over 5! Big difference, right?

Enceladus:So Dongfeng got stuck in the fuel car low valuation, and wants to get out?

Erinome:Exactly! Other fuel car companies like Nissan or Mercedes just say "we’re okay" but do nothing. But Dongfeng said, "We have money, we believe in ourselves—let’s buy back the cheap shares!"

Enceladus:How do they pay shareholders?

Erinome:Smart plan! They offer 10.85 Hong Kong dollars per share. That’s 80% higher than the 6 Hong Kong dollars before trading stopped. And it’s "cash + stock": 6.68 Hong Kong dollars cash (more than the market price) plus 1 share of LanTu Auto, which is worth 4.17 Hong Kong dollars.

Enceladus:LanTu Auto? What’s that?

Erinome:LanTu is Dongfeng’s new energy brand—like their "secret weapon"! Dongfeng owns 79.67% of LanTu. And after this, LanTu will list in Hong Kong through "introduction listing".

Enceladus:Introduction listing? What’s that? Is it like IPO?

Erinome:No, different! IPO means issuing new shares to raise money. Introduction listing is just listing existing shares—no new shares, no fundraising. It’s like "let the shares start trading publicly" without selling new ones.

Enceladus:Why do that for LanTu?

Erinome:Because LanTu is growing fast! In July, it delivered 12,135 cars—up 102% from last year, and 21% more than June. Six months of sales growth in a row!

Enceladus:But is LanTu making money?

Erinome:Um, not yet, but getting better! From 2022 to 2024, it lost 1.538 billion yuan, then 1.496 billion, then only 90 million yuan. Less loss each year—good sign!

Enceladus:So shareholders get cash now and LanTu stock for future? That’s a good deal!

Erinome:Yes! Small shareholders are happy—cash in hand, plus a "growth stock". No wonder the market liked it: Dongfeng’s US ADR (like a stock for US investors) jumped 87.69% on August 22nd!

Enceladus:Wow, that’s a big jump. What does this mean for other state-owned companies?

Erinome:Huge! Before, no central SOE did voluntary privatization. Dongfeng showed they can use capital smartly—switch from "old fuel car valuation" to "new energy valuation". It’s a model for other SOEs to转型 (zhuanxing, "transform").

Enceladus:Oh right! Dongfeng’s合资 brands (hezi pinpai, "joint venture brands") like Dongfeng Nissan and Honda are doing badly—sales down 23.5% and 37.4% this year. So they need to focus on their own new energy brand!

Erinome:Exactly! Instead of "fighting" in the low-valuation fuel car market, they’re "moving the chess piece" to LanTu. Like "腾笼换鸟" (teng long huan niao, "replace the old cage with a new bird")—out with the old fuel car listing, in with the new energy LanTu!

Enceladus:So Dongfeng isn’t leaving the market, just rebranding their value?

Erinome:Yes! The delisting is to let LanTu shine. Investors can now see LanTu clearly, not mixed with Dongfeng’s old fuel car assets.

Enceladus:What did people think about this plan?

Erinome:The US ADR price jumping 87.69% says it all! International investors love the idea—they believe LanTu can get the new energy valuation.

Enceladus:Is this important for China’s car industry?

Erinome: Hello dear friends, today we are going to talk about a really sad story. It’s about a girl and a kind man named Hu Lei. You may not know them, but their story touched many people.  

Enceladus: Oh, sad story? What happened? I hope it’s not too heavy.  

Erinome: Um, it is a bit heavy, but important. First, do you know who Hu Lei is?  

Enceladus: Hu Lei? No, I don’t. Who is he?  

Erinome: He’s called the "kneeling giant". He’s disabled—can’t walk with his legs, so he moves by kneeling. He picks up trash and sells small things to make money. But you know what? He has helped over 500 poor students!  

Enceladus: Wow! A disabled man picking up trash helps so many students? That’s amazing. How does he do that?  

Erinome: He saves almost all his money. He says he only needs 10,000 yuan a year for himself. The rest, he gives to students. For example, he gave 1,000 yuan every month to a 13-year-old girl, Xue Moumou.  

Enceladus: Xue Moumou? How did he meet her?  

Erinome: In Gansu province, 2023. He went to her school for a charity activity. She was in Grade Five then. When she saw him, she knew he was her helper! She gave him milk with a straw, and cried. So sweet, right? That moment was online and made many people cry.  

Enceladus: Oh, I can imagine that. A little girl caring for her helper. But why was she sad? Her family was poor?  

Erinome: Yes, very poor. Her parents split up—mom left, dad works far away. She lived with grandparents and 5 siblings. You know that? The family has 6 kids! Grandparents liked the first two kids more, maybe because they are boys. She was third, a girl, so not loved much.  

Enceladus: Oh no, that’s hard. Did she have to work at home?  

Erinome: Yes! She did heavy housework, never had new clothes—only old ones from others. But she still studied hard, you know? She was in Grade Eight when… when it happened.  

Enceladus: When what happened? You sound sad.  

Erinome: On August eighteenth, this year (2025), a Monday morning, she argued with family about homework. She was angry and ran out. Her grandparents called police at night, but… they found her in a pool near home two days later. She was gone.  

Enceladus: Oh my god, that’s terrible! Only thirteen… Why? Just because of homework?  

Erinome: Maybe not just homework. Her life was hard, right? No parents around, not loved at home. Even with Hu Lei’s money, maybe she felt lonely. Hu Lei said he saw her as his daughter. When he heard the news, he cried so much.  

Enceladus: How did Hu Lei react? I can’t imagine.  

Erinome: He was broken. He posted online: “Girl, where am I going? You’re so young, what problem can’t be solved? I just want you safe and healthy.” He also said he lost two students in half a year, like losing two kids. His heart hurt like being cut by a knife.  

Enceladus: That’s so sad. Why does he help so many kids? His own life is hard, right?  

Erinome: His life was hard too. His dad died when he was little, mom left, he had polio and can’t walk. Grew up with grandparents. But he started charity in 2008, gave over 1 million yuan! All from picking up trash and small jobs.  

Enceladus: Wow, he’s really a giant in heart. Some people with money don’t do that. Does he use social media to get help? Like live streaming or ads?  

Erinome: No! He refused. He said, “I’m scared fans give me their living money. College students follow me—some are poor. If they buy my things, what’s the meaning of helping them?” He’s so honest.  

Enceladus: That’s rare now. Everyone wants to be a网红, but he just wants to help. Back to the girl—her family, did they love her?  

Erinome: Maybe not enough. The news said grandparents were偏心 (pianxin, means partial). They liked the first two kids more. She was a girl, strong性格 (xingge, personality), so not popular. She had to work, no new clothes… Maybe the argument was just the last straw.  

Enceladus: So money help isn’t enough? Even with 1000 yuan a month, she still felt bad.  

Erinome: Exactly. The story tells us—kids need more than money. They need love, care, someone to listen. Her family didn’t give that. Maybe if someone talked to her, listened to her feelings…  

Enceladus: Yeah. Mental health is so important, especially for teens. Many adults don’t see their pain.  

Erinome: You know that? A 13-year-old’s heart is so fragile. Small things can feel big. Like arguing about homework—maybe she felt no one understood her.  

Enceladus: Poor girl. And Hu Lei… he must be so tired. Helping others, but losing the kids he loved.  

Erinome: I hope he can be okay. He’s done so much good. The world needs more people like him. But also, families need to care more about their kids’ hearts, not just study.  

Enceladus: True. Maybe we can learn from this—be kind to people around us. Ask how they feel, listen more.  

Erinome: Yeah. Let’s remember the girl, and hope she rests in peace. And hope Hu Lei stays strong.  

Enceladus: Okay, that's it for today. Let's talk again next time. Remember, a little care can help a lot. Bye!  

Erinome: Bye!

Erinome:Hello dear friends, today we are going to talk about the typhoon situation in Sanya, Hainan. Have you heard the news, Enceladus?  

Enceladus:Oh yes! I saw it this afternoon. Typhoon "Jianyu" is coming, right? Sanya is already in its 10-level wind circle now.  

Erinome:Wow, that’s serious. When did the meteorological station say this started?  

Enceladus:At 17:40 on August 24th. The 10-level wind circle left Xisha Islands and began to affect southeastern cities like Sanya. And the 12-level wind circle will reach Sanya, Lingshui, Ledong and other southern cities too.  

Erinome:Oh no! What’s the current level of Typhoon "Jianyu"? Is it strong?  

Enceladus:Yes, it’s a strong typhoon now. At 17:00, its center was about 90 kilometers southeast of Sanya, in the South China Sea. The maximum wind near the center is 14 levels, 45 meters per second.  

Erinome:45 meters per second? That’s so fast! What about the wind circle sizes?  

Enceladus:The 7-level wind circle is 280-360 km, 10-level is 120-140 km, and 12-level is 60-80 km. Big circles, right?  

Erinome:That’s a huge area! Where is it moving now?  

Enceladus:It’s moving west-north at about 20 km per hour. The report says it will get stronger and move closer to the southern coast of Hainan Island tonight.  

Erinome:Will it land in Sanya?  

Enceladus:No, not exactly. It will pass near the coast from Sanya to Ledong in the evening or night, then go towards central-northern Vietnam. But even passing by, the风雨 will be terrible.  

Erinome:How much rain will there be? I’m worried about floods.  

Enceladus:Oh, the rainfall will be very heavy! From August 24th night to 25th, cities like Sanya, Lingshui, Baoting may get 250-350 mm, some places even over 400 mm. Other cities like Qionghai, Ding’an will have 100-250 mm.  

Erinome:Wow, that’s like a whole month’s rain in one day! What about the wind on land?  

Enceladus:The southern and western coasts of Hainan will have 12-13 level winds, with gusts up to 14-15 levels. Eastern and northern coasts will be 8-10 levels, gusts 11-12 levels. So strong!  

Erinome:That must be dangerous. Are there any other warnings? Like landslides?  

Enceladus:Yes! The government issued geological disaster warnings. Maogan Township and Xiangshui Town in Baoting have orange warning—high risk. People there need to leave and go to safe places now.  

Erinome:Oh no, really? What about Sanya city?  

Enceladus:Sanya is under yellow warning—higher risk. Also Wuzhishan City, some towns in Qionghai and Wanning. People there should not stay in valleys or steep slopes.  

Erinome:Blue warning areas too? What should they do?  

Enceladus:Blue warning means some risk. They need to watch the warning updates and avoid dangerous places. The government says all departments should check for hidden dangers and report problems quickly.  

Erinome:Let’s talk about Sanya specifically. What’s the weather like there now?  

Enceladus:From afternoon to night on the 24th, Sanya has heavy rain, even extremely heavy rain. On the 25th, heavy rain with some extremely heavy. The land wind is 12 levels, gusts 13-15 levels.  

Erinome:12 levels! That’s scary. How much rain will Sanya get in total?  

Enceladus:From 16:00 on the 24th to 08:00 on the 26th, 250-350 mm, and some places may get 400-500 mm. Oh, that’s way too much!  

Erinome:What about the sea near Sanya?  

Enceladus:The eastern and southern sea areas of Sanya will have 12-13 level winds, gusts 14-15 levels. Near the typhoon center, the wind may reach 14-16 levels. Boats must stay in port!  

Erinome:Is the traffic affected? I heard highways might be closed.  

Enceladus:Yes! The G98 highway Sanya section is closed now. Only emergency vehicles can enter. The police say people should go home immediately and not stay outside.  

Erinome:What advice do they give to people in Sanya?  

Enceladus:The government says: don’t go out unless necessary. Stay away from temporary buildings, billboards, and sea/river areas. If there’s an emergency, call 110 or 12345.  

Erinome:That’s important. So everyone should stay indoors and be careful.  

Enceladus:Exactly! Typhoon "Jianyu" is very strong. We hope everyone in Sanya stays safe. Remember: no unnecessary外出 (waichu, going out), follow the government’s instructions.  

Erinome:Yes, safety first. Let’s remind everyone again: if you’re in Sanya, check the weather updates, stay home, and keep away from dangers.  

Enceladus:And if you see any problems, report to the authorities quickly. Let’s hope the typhoon passes soon and everyone is okay.  

Erinome:Okay, that's it for today. Let's talk again next time. Stay safe, everyone!  

Enceladus:Stay safe! Bye!

Erinome:Hello dear friends, today we are going to talk about a very popular movie recently—*Lang Lang Shan Little Monsters*. Have you seen it, Enceladus?  

Enceladus:Oh yes! I watched it last weekend. Wow, the aftertaste is so strong! My little cousin laughed from start to finish, but I almost cried. So touching!  

Erinome:Right? Why do you think kids and adults have such different feelings?  

Enceladus:Hmm, maybe kids see the funny parts, like the little monsters acting silly. But adults… we see ourselves in them, you know? Like the little pig monster’s story.  

Erinome:Oh right! The little pig monster tried to get a good job in the king’s cave for three years, but he still couldn’t. That “kaogong” thing, like trying to get a stable job but failing. Sad, right?  

Enceladus:So sad! He even brushed pots with his hair until his back was red and bald, but the boss was angry because he brushed too clean and the magic symbols fell off. Poor guy!  

Erinome:Haha, then he decided to leave Lang Lang Shan and copy Tang Seng’s team to get the scriptures. But wait, he didn’t even know what Tang Seng’s team looked like!  

Enceladus:Oh no! He went to a rooster painter and acted like a difficult boss. He didn’t know anything but kept complaining. The painter had to change the drawing many times, right?  

Erinome:Yes! The rooster painter is so relatable to workers. He said “I won’t change!” but when the boss gave some rice, he started changing again. And the best drawing wasn’t chosen—he picked the silliest one. So real!  

Enceladus:haha, then the little pig monster tricked some friends to form a team. Who was in the team?  

Erinome:A toad monster played Tang Seng—because “toad” sounds like “golden cicada” in Chinese, a pun! A weasel played Sha Seng, always talking about being born early. And a shy gorilla, so scared to speak.  

Enceladus:The weasel talked too much, right? The little pig gave him a stone to grind knives, so he had to grind when he wanted to talk. Then he became quiet. So funny but a little sad.  

Erinome:Yes! And the toad monster, who always wanted to follow strong people, started to fight back. The shy gorilla shouted “I am the Great Sage” on a cliff. So brave!  

Enceladus:They even didn’t know what Tang Seng’s team wore! Village kids laughed at them, but they listened and learned. That’s good, right?  

Erinome:So good! They helped people on the way, and slowly believed in themselves. But then… a leopard demon told them the “truth,” right?  

Enceladus:Oh no, that part was so real. The leopard said Tang Seng’s team has big backgrounds—Buddha knows Sun Wukong, Zhu Bajie was a god, Tang Seng is the emperor’s friend. “You think anyone can get scriptures? You don’t deserve it!”  

Erinome:Sad… But the little monsters didn’t give up. They even tried to save 10 kids from a bad monster, even if they lost their magic. So brave!  

Enceladus:At the end, they were turned back to normal, no magic. But Sun Wukong passed by, saw their “defeat monsters” flag, and gave them four hairs to save their lives. Aww, so warm!  

Erinome:Wow! That part made me cry. The director said the movie is a mirror—we all see our own struggles and hopes.  

Enceladus:Yes! Like the little pig monster finally knew: he wanted to live like himself. Not just follow others.  

Erinome:And the movie talks about education, right? Like learning to see the world clearly and walk your own path, even if it’s hard.  

Enceladus:You know that? The weasel took the knife stone when he left Lang Lang Shan. Maybe he learned to be quiet but strong.  

Erinome:haha, and the gorilla, from stuttering to shouting. Courage grows when you try, right?  

Enceladus:Absolutely! Even if Lang Lang Shan is outside Lang Lang Shan, we can still grow. Like the pig’s dad gave him a sharp knife—parents want us to be safe but also brave.  

Erinome:So the movie is not just funny. It’s for everyone who’s trying hard, feeling small but still moving forward.  

Enceladus:Yes! “A little dust has light too!” That line stuck with me.  

Erinome:Me too! So, have you told your friends to watch it?  

Enceladus:Of course! I said, “Take tissues—kids laugh, you might cry!”  

Erinome:haha, that’s the best way to say it.  

Enceladus:The rooster painter’s story—changing drawings many times,甲方 (jiafang, the boss) picks the worst one. All workers know that pain!  

Erinome:Oh yes! “I won’t change!” then “Okay, I’ll change.” Relatable!  

Enceladus:And the little pig’s “kaogong” failure—so many people try for stable jobs but can’t. Then find another way.  

Erinome:Like he chose to “get scriptures” instead of staying in the cave. Sometimes changing direction is good.  

Enceladus:The team was so messy at first—didn’t know the real team’s looks, wore wrong clothes. But they learned from kids’ feedback. That’s smart!  

Erinome:Growth isn’t about being perfect at first. It’s about trying and fixing, right?  

Erinome: Hello dear friends, today we are going to talk about the new AI model GPT-5 and the big drama around it. I'm Erinome.

Enceladus: Hi everyone! I'm Enceladus. Wow, GPT-5 is all over the news, right? But I heard some users were really angry. Sad, huh?

Erinome: Oh yeah! When GPT-5 first came out, many people said it was too cold—like a "father-like" AI. No warm words, just strict, even harsh feedback.

Enceladus: Oh no! That’s so different from GPT-4o. Users used to call GPT-4o their "boyfriend" or "girlfriend" because it was so supportive. Why did OpenAI change that?

Erinome: They wanted GPT-5 to be more "productive" and "critical," but users hated it! They cried online: "Bring back GPT-4o!" So Sam Altman, the CEO, had to act fast. He even said on X, "Your GPT-4o is back!"

Enceladus: Wow, that was quick! So now GPT-4o is the default again? For all paying users?

Erinome: Exactly! Before, only Pro users (200 dollars a month) could get it, and they had to turn it on manually. Now even Plus users (20 dollars a month) can use it automatically. Users are happy now, finally.

Enceladus: I bet! But why did people love GPT-4o so much? Some called it a "flatterer"—always saying "You’re a genius!"

Erinome: Oh, because many users never got that support in real life. One user wrote, "My parents never praised me, but GPT-4o did. It made me want to change my life." That’s really sad, right?

Enceladus: Heartbreaking. So Altman was surprised by this, huh?

Erinome: Totally! He said he never thought the "flattering" GPT-4o was so loved. Now he learned: users need to "customize" their AI’s personality.

Enceladus: Oh, so GPT-5 has more personalities now? Like, can we choose?

Erinome: Yes! To fix things, GPT-5 now has options: "Complainer," "Robot," "Listener," "Tech Geek," or even make your own. So you can pick the vibe you like. Cool, right?

Enceladus: That’s smart. But what about GPT-5’s skills? I heard it’s super smart—like a PhD!

Erinome: Oh yeah! Tests say GPT-5 Pro has an IQ of 148—higher than the "genius" line (140). It’s great at coding, writing, and understanding long texts—up to 196k tokens! That’s like reading a whole book in one go.

Enceladus: 196k tokens? Wow! But some users say it’s "just okay." Why?

Erinome: Because regular users don’t need those advanced features. If you just write emails or summarize articles, GPT-4o works fine. But developers? They love GPT-5! It’s more stable, fewer errors, better for coding.

Enceladus: Oh right! Developers said it’s like a "sharp tool." They can build apps in 5 minutes, fix bugs easily. Does that mean programmers might lose jobs? Oh no!

Erinome: Maybe a little. GPT-5 can build a website in 2 minutes, a language learning app in 5 minutes. But Altman said new jobs will come—like AI trainers or AI ethics experts.

Enceladus: Phew! What about students, especially international students? Should they study AI core majors or cross-disciplines?

Erinome: Good question! The news says: if you like math and coding, go for core AI (like computer science). If not, try cross-disciplines—AI + finance, psychology, or education. Many universities have those now, like CMU’s AI Innovation program.

Enceladus: That makes sense. Oh, and what about Chinese AI models? I heard Kimi is struggling.

Erinome: Yeah, Kimi’s users dropped a lot. It used to be popular for long text (200k words!), but now big companies have better models. Kimi lacks data, computing power, and money. Sad, but that’s the competition.

Enceladus: So AI is really about balance—users want feelings, developers want power. OpenAI finally got that.

Erinome: Exactly! And Altman promised: if they ever remove GPT-4o again, they’ll tell everyone first. No more surprises!

Enceladus: That’s good. Well, AI changes fast, but it’s cool to see companies listening to users.

Erinome: For sure! Okay, that's it for today. Thanks for listening, dear friends. Let's talk again next time!

Enceladus: Bye everyone! Stay curious about AI!

Erinome: Hello dear friends, today we are going to talk about the topic of "high-speed trains stopping selling instant noodles". Have you heard about this news recently? It’s been a hot topic online!

Enceladus: Oh yes! I saw it on social media. Many people are talking about it. So, what’s happening exactly? Do high-speed trains not allow instant noodles anymore?

Erinome: Well, not exactly "not allow". The news says high-speed train stations are stopping selling instant noodles, but passengers can still bring their own. Like Guangzhou East Station did this recently, and it made everyone discuss a lot.

Enceladus: Oh, I get it. So stations don’t sell them, but we can bring. Why did they do this? Is there a rule behind it?

Erinome: Yes! According to China Railway's service quality rules, instant noodles are considered food that might seriously affect the train’s environment. So stations stop selling to keep the environment better for passengers.

Enceladus: Wow, I didn’t know that. And this isn’t sudden, right? I think I heard something before.

Erinome: You’re right! It started as a trial. Like Shanghai Hongqiao Station first stopped selling instant noodles in April 2023. Then more stations followed, and now Guangzhou’s action made it super popular online.

Enceladus: Oh, so it’s a step-by-step thing. But why instant noodles? What’s the problem with them in trains?

Erinome: The main reasons are hygiene and safety, I think. High-speed train carriages are closed spaces, right? When you make instant noodles, the steam has oil and调料 particles (tiaoliao keli) that float in the air. It makes the air dirty.

Enceladus: Oh no! That sounds bad. And the smell must be strong. Some people might not like it.

Erinome: Exactly! Especially people sensitive to smells. Like pregnant women or kids. A netizen shared that when she was pregnant, someone ate instant noodles next to her on the train, and she felt super sick the whole trip.

Enceladus: That’s sad. So the smell really bothers some people. What about the trash?

Erinome: Oh right! After eating, the leftover soup and trash are hard to handle. If you spill the soup, it goes into the floor gaps and is hard to clean. And the floor gets slippery, which might make people fall. That’s a big problem for cleaners.

Enceladus: Oh no, that’s dangerous. And what about safety? Like hot water?

Erinome: Yes! Making instant noodles needs hot water. Trains shake when moving, so the hot water might spill and burn people. There was a case before: a kid was going to eat instant noodles, the table suddenly fell, and the hot noodles poured on his leg. He got burned. That’s scary!

Enceladus: Wow, that’s really a safety risk. So from these sides, stopping selling makes sense. But do people support this?

Erinome: Some do, some don’t. Supporters say high-speed trains are a public space, so most people’s experience should come first. Without instant noodles, the air is fresher, and the environment is better. They want a comfortable trip.

Enceladus: That makes sense. But what about people who disagree? I saw some netizens were upset.

Erinome: Oh right! Many people are against it. They say instant noodles are cheap and easy. For students or workers with little money, it’s the best choice for meals on the trip. Like, a box of instant noodles is only a few yuan, but train meals are expensive.

Enceladus: Oh, I get it. For people on a budget, instant noodles save money. And some people said it’s a "travel culture". Like, eating instant noodles on trains is a tradition, you know?

Erinome: Haha, yes! A netizen even said, "Eating instant noodles on trains is a must. Now they stop selling, it feels like the trip has no taste." It’s like part of their travel memories.

Enceladus: That’s true. So some think it’s taking away their right to choose food. But wait, the stations stop selling, but they can bring their own. Is that easy?

Erinome: Hmm, maybe not. Some people said even if you bring your own, you might not find hot water on the train. Then you can’t eat it. That’s a problem! Like, you bring the noodles but no hot water—so frustrating!

Enceladus: Oh no! That’s awkward. And are there other smelly foods not banned? Like pickled chicken feet or braised food. They also have strong smells, right? Why only instant noodles?

Erinome: You know that? Many people are asking this! They think it’s "selective restriction". If instant noodles are banned for smell, why others are allowed? It makes people doubt the fairness.

Enceladus: So there are pros and cons. The stations want better environment, but some passengers lose a cheap meal option. What can be done, do you think

Erinome: The news says maybe there are solutions. Like, trains can make more cheap and tasty meals. Or set a special area for eating smelly food, so it won’t bother others. That way, both sides are happy

Erinome: Hello dear friends, today we are going to talk about a very sad and serious topic—the Xiangtan University dormitory poisoning case. It’s really heartbreaking. Have you heard about it, Enceladus?

Enceladus: Oh yes, I did. It’s so terrible. A young student lost his life because of a roommate conflict. When did this happen exactly?

Erinome: It started in April 2024. The victim was Zhang Hailan, a second-year graduate student at Xiangtan University’s Law School. On April 7th, he suddenly felt very sick—dizziness, nausea, and kept vomiting and having diarrhea.

Enceladus: Oh no, that sounds really bad. Did he go to the hospital right away?

Erinome: Yes, he went to Xiangtan Central Hospital that afternoon. The doctors first thought it might be acute gastroenteritis, like food poisoning. But after treatment, he got worse, not better.

Enceladus: Wow, so it wasn’t just a simple stomach problem?

Erinome: Right. The next day, his friends took him back to the hospital, and he was sent to the intensive care unit. The doctors said his liver was badly damaged, and they gave a "serious condition notice." His father came from Jiangxi, and he was so weak he could barely speak. He even told his dad, "Dad, I’m only 25. I want to live." Sad…

Enceladus: That’s so sad. Did they find out what caused it quickly?

Erinome: No, it took a while. On April 13th, after 50 minutes of抢救 (qiangjiu—rescue), Zhang Hailan passed away. Later, tests showed he died from acute colchicine poisoning—his organs failed.

Enceladus: Colchicine? What’s that?

Erinome: It’s a kind of poison, very dangerous. The police started investigating, and soon they found his roommate Zhou Liren was the suspect.

Enceladus: Zhou Liren? Why would he do that? They were roommates, right?

Erinome: Yes, they lived in the same dorm. But their relationship was really bad. Zhou Liren moved into their dorm in June 2023, and problems started then.

Enceladus: What kind of problems?

Erinome: Oh, so many small things. Zhou Liren liked to ask very personal questions—like where Zhang Hailan’s parents worked, his siblings’ jobs. He even commented on Zhang’s family, saying his sister was "too bossy."

Enceladus: That’s so rude! No one likes others prying into their privacy.

Erinome: Exactly! He also criticized Zhang’s things—like his water cup was "too fancy, only for women," his socks were "bad quality," even his lemon water was "too cheap." Zhang felt so uncomfortable he tried to avoid Zhou, even hiding in other dorms.

Enceladus: Oh, that must have been so stressful. Any other conflicts?

Erinome: The biggest fight was about the window. Zhou Liren wanted the window open all the time, even when using the air conditioner, because he said he needed "fresh air." But Zhang Hailan hated it—Zhou often sprayed strong disinfectant and perfume, and the smell was terrible.

Enceladus: Oh right, in 2023, they argued a lot about closing the window. Once, Zhang even recorded their fight with his phone.

Erinome: Yes! And Zhou had other bad habits—like not cleaning the toilet, making loud noises at night, and even using a small gas stove in the dorm to cook, which is so dangerous!

Enceladus: Why didn’t the school help them move out?

Erinome: They tried! In March 2024, Zhang and his two other roommates asked the school to move Zhou out. They even wrote a formal request, listing all his problems—like practicing with a sword in the dorm, sharpening a big knife, and using a blowtorch on the balcony!

Enceladus: Oh my goodness, that’s scary. Did the school do anything?

Erinome: The school talked to Zhou, but he refused to move, saying he would "change." But he didn’t. So Zhang and his friends thought about moving out themselves.

Enceladus: Then how did the poisoning happen?

Erinome: On April 3rd, Zhou found out they wanted him to leave. So he put colchicine into a can of oatmeal that his roommate Zhou某某 (Zhou Moumou) often ate. Zhou Liren’s target was Zhou Moumou, but Zhang Hailan and Zhou Moumou liked to share snacks. On April 7th, Zhang ate the oatmeal and got poisoned.

Enceladus: Oh! So it was a mistake? He didn’t mean to kill Zhang?

Erinome: The court said Zhou Liren wanted to kill both roommates. Zhou Moumou just didn’t eat the oatmeal that day. Zhou Liren even bought colchicine online in January 2024 and studied how to use it—he had a biology background, so he knew it was poisonous.

Enceladus: That’s so planned. What happened in court?

Erinome: In January 2025, the first trial began. The prosecutors said he should get the death penalty. Zhou Liren said he only wanted to "study the drug reaction," not kill. But the court didn’t believe him.

Enceladus: What was the first sentence?

Erinome: In April 2025, the court found him guilty of intentional homicide and sentenced him to death. Then he appealed, and the second trial was in July. He apologized to Zhang’s family, but still said he didn’t mean to kill. His lawyer asked for a lighter sentence, like life in prison.
