When you travel to any Asian country, you need to know that things are a little different there, and you have to accept the cultural differences. In China, you need to be ultra-vigilant on these, because some actions (even if you don't want them to be) are considered rude for some reason. Do not ever leave the chopsticks stuck in rice when having meals with a Chinese restaurant, because that is considered rude. Also, no matter how generous you are, do not tip at any restaurant or a hotel, because that's also considered rude and impolite. Remember not to point at people or things when you are there too – as this is considered rude too!
