Hey, I am going on a trip to China this Saturday and have been reading/hearing a lot of stuff about it. Both good and bad. Most of it has been good, but I am still concerned with the bad parts. Can someone give me any insight on the following: Do not drink water if its not bottled Do not leave valuables in your hotel room as maids will steal them Street vendors will rip you off You will be pick pocketed The air quality is very bad Any tips on how to secure my belongings? thx
