Re:

I met a Chinese girl when I was in Shanghai, I asked her if she could escort me for a city tour and asked for her mobile number, so I could call her.

She got excited and said: "sex sex sex, want free sex for tonight"

Wow, I'm guessing this is how Chinese women express their hospitality!

But then, My friend interpreted for me & told me what she really said: 666136429.

I don't understand. What should I do with this number and who is she ?
