Well, the time that I got a problem and worked hard on it according to the Internet, was all about how to book the hotel in another city of my country, when I was doing the arrangement of my long journey. You know, the main problem was that I was not sure if I could find a proper place or hotel to live in, especially in such a super big city, you know, it has large population by the way, 10 million I suppose. For my part, it could a big challenge to make reservations or do something in advance. more importantly, I haven't been to the city of Peking before, certainly, I was a bit worried and nervous if I could solve it on my own. Thanks to the Internet and related online travelling forums, I got hundreds of useful advice. Some kind-hearted net pals who grew up in Beijing, really did a big favor for real. We talked online, texted messages on the forums as well. Not very long, but in 2 days, we worked it out. I was like a bit shocked since I haven't imagined that things went on so smoothly. The Internet is now playing an increasingly important role in my personal life. That is it.
