I used to work in China for 2 years (Shanghai to be exact) and I've seen what goes around there with my own eyes. I used to call Shanghai "Sin City" with good reason. China is a place where your faith, conviction, core believes are put to the ultimate test and I have seen many fail miserably to stand firm and be faithful.
I'll give you a real life story of a male friend who came to visit me while I was there. Upon arrival, from the airport he took the subway then bus to get my place. Purely just by asking around for directions, and holding a map, he had no less than 3 girls approach him and by the time he reached my place he had 3 phone numbers !!!!! That's how scary that place is.
