Tips when visiting China

1. Don't wear shoes inside someone else's house.
2. Don't put toilet paper in the toilet if there is a bin next to the toilet. The paper goes in the bin. Not an issue in hotels. (The pipes will get clogged)
3. Don't do drugs or have a gun in China. If you are lucky they will deport you. If you are unlucky you will go to jail.
4. Don't tip unless you really really want to or if you are in a high end hotel/restaurant. They will generally run after you with the change and be confused.
5. Don't be an ignorant tourist. There are common scams in each city listed on most travel sites and guides. China is safe (unless you are driving, or walking near people who are driving, or trying to breathe anywhere near a city) but there are lots of scams like the art student scam, the tea house scam, etc.
