What are some of the unwritten rules of China?
Grainne O’Reilly ： Do not mention the three ‘T’s’, that is Tiananmen Square, Tibet and Taiwan. These are very delicate subjects for many Chinese people and it is best not to get drawn into any conversations about these subjects and certainly not to bring them up. The West’s view of Communism is often vastly different from the day to day experience of living in a Communist country, so be aware that what is commonly known, understood and expected may not necessarily be so!
Eamon Dan ： When a man asks a girl out, man should pay the bills.
When you see senior people standing on public transportation vehicles, you should give out your seat.
In northern China, if you ask your friend to join dinner/lunch with you, you should pay the bill. And they should return you the favor at next time you guys eat together.
Girls don’t wear clothes which can not cover their cleavages no matter how hot the weather is.
Don’t be obsessed with your private space. China is very crowded.
It is ok to negotiate with government officials when you make mistakes, police officers won’t cuff you nor shoot you.
Don’t criticize the government if you don’t know the people you are talking to very well. Very few Chinese people distinguish people/country/government.
Jamie Cawley ： As advised elsewhere avoid political topics related to China because you will be very misinformed about them – a failing of the west is to think that reading occasional news articles on China (many themselves absurdly misinformed) entitles then to be confident of their political views. If someone Chinese asked you what your views are on slavery in the US – does it still exist covertly? – you would be irked.
正如其他人所建议的那样，避免与中国政治有关的话题，因为你会对他们产生误解 – 西方的失败是认为偶尔阅读有关中国的新闻文章（许多人自己荒谬地误导），他们有权对自己的政治观点充满信心。如果有人问你对美国奴隶制的看法是什么 – 它是否仍然秘密存在？- 你会生气的。
Anonymous ： Having a foreign friends is cool, especially make friends with European or American people. It means the Chinese person is good at English or get a good chance to practise English.
Katie Pedro ： Unwritten rules, originally mean sex exchange for favor from those who are in power.
Andy Lee Chaisiri ： PRC and Taiwanese political parties are like an American fraternity, drinking hard is a requirement and most of the important decisions are done while drunk. A guy I know has worked as a journalist for both the CCP and KMT and recalls how he’s watched countless interns pass out into oblivion trying to keep up with the fat old dudes running their respective nations.
Jean-Louis DeMontaron ：
When invited for dinner, do not eat the rice brought at the end of the meal, the host is showing that he hopes you have had enough to eat but the rice proves he still has food left, eating the rice will shame the host.
Never stick your chopsticks into your bowl of rice, this is reserved for the dead.
The Chinese promote the drinking of hot water as very healthful. My wife drinks hot (boiled) water all the time.
