I agree with CS Mike. When i visited China the first time I left my laptop in my hotel room just sitting in it's case beside the table. I never had any problems, everything was in it's place and nothing was stolen. The other 2 times I visited China I was staying at my wife's house so that doesn't count. Like CS Mike has mentioned, if you are in a reputable hotel there should be no problems what so ever, or just use the hotel safe if you feel afraid of getting it stolen. I usually carried my passport with me at all times, but then I decided to lock it in the hotel safe that was in my room. I never encountered any problems with my personal belongings when in China, I even left things sitting on the desk and tables in my hotel room and everything was still there when I returned. The cleaning lady would sometimes move the items when she cleaned the room and place them, that was all. The only person that can really enter your room is the cleaning lady, and I do not think she will risk loosing her job and have other implications and problems that she could face if ever she was caught stealing something from a clients room.
