There was this Chinese girl at a travel agency 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 to make arrangements.
She got excited and said:
"sex sex sex, wan free sex for tonigh"
Wow, I'm guessing this is how Chinese women express their hospitality!
But then, my friend, who’d been to China before, interpreted it for me and told me what she really said : 666136429
