Great conversation topics with your Chinese host are family, children, football or other sports, food or industry. With the topics you can build up a closer relationship with your host. Please try to be open about your own personal life also, this is very much appreciated.
If you are talking with Chinese please be very careful when talking about Tibet, Taiwan, Japan or Chinese politics. Chinese do not like to talk about these subjects, but also they are very easy offended with these conversation topics. Try not to mention these topics or keep a neutral opinion.
Avoid discussing Diaoyu Island
Diaoyu Island has been a cause of conflicts between China and Japan for decades. This is the one of the most concerned political issues in Chinese society. The Japanese culture has a great influence on younger generation of China, but politically, the hatred towards the Japanese among Chinese citizens has never diminished since WWII. Such emotions are still easily provoked when it comes to politics. Therefore, it is not advised to talk about these issues with Chinese people.
