China is a country with a long history, and Chinese social manners are very different from English ones. Let me tell you some of them.
Firstly, you should shake hands when you meet someone for the first time. Secondly, you should bring a gift when you go to a party or visit a friend and be sure to arrive on time or a few minutes earlier. Thirdly, when you eat meals with others, it's rude to point at others with your chopsticks. And don't make any noise when you have your soup. You should know the rules so that both the guests and hosts are comfortable at table.
