I met a Chinese girl when I was in Shanghai, I asked her if she would 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 TO NIGHT".
Wow, I'm guessing this is how Chinese woman expresses hospitality!
But then, my friend interpreted for me and told me what she really said it was: "6 6 6 1 3 6 4 2 9"
