At a travel agency in Shanghai, I asked the Chinese girl behind the counter if she could escort me on a city tour and asked her for her mobile number so I could call her to make arrangements.
She gave me a big smile, nodded her head and said, "For sex sex, wan free sex, for tonigh free."
I replied, "Wow, you Chinese women are really hospitable!"
A guy standing next to me overheard, tapped me on the shoulder and said, "Don't get excited. What she said was: 466 136 4293!"
