wǒ xiǎng qǐng jiào nǐ yī gè wèn tí 。

我想请教你一个问题。

I'd like to ask you a question.

shén me wèn tí ， nǐ shuō a ， wǒ zhī wú bù yán 。

什么问题，你说啊，我知无不言。

What question? Split it. I'll tell you everything I know.

wǒ qián liǎng tiān hé yī gè nǚ hái biǎo bái ， tā shuō wǒ men shì lǎo tiě ， shén me yì sī ？

我前两天和一个女孩表白，她说我们是老铁，什么意思？

I confessed my love to a girl couple of days ago, and she said we were "Lao tie" or "old iron". What did she mean?

lǎo tiě jiù shì hǎo gē men de yì sī ， kàn lái nǐ bèi jù jué le 。

老铁就是好哥们的意思，看来你被拒绝了。

"Lao tie" means good buddy or close friend. It looks like you've been rejected.
