There are different customs in different countries. let me tell you some customs in China.

Firstly, people are supposed to shake hands when they meet for the first time instead of bowing or kissing. Secondly, It' s important to be on time in China, but it' s OK if you arrive a bit late because of something special. And We usually make plans to visit a friend's house. Finally, it is necessary for you to learn about the table manners in China. If you're invited for dinner, you're not supposed to start eating first if there are older people at the table. It's impolite to point at anyone with your chopsticks . Also, you shouldn' t stick your chopsticks into the food. It's polite of you to say something good about the dishes while eating.

Hope you have a great time in China.
