The Chinese culture is very interesting, and very different from American culture. American culture is very diverse. America was founded on foreigners. Many aliens migrate to America every year.
Chinese culture is very uninfluenced. This is, because China was closed off for many years without trading and not being influenced by other cultures. While I was in China there were many misconceptions of American culture and Chinese culture.
I found Chinese women find profane and derogatory language very offensive. Some will even go as far as asking you not to speak that way in front of them. In America some women will swear more than men. I would not call them sheltered, but I would say that have not been exposed to that type of environment like most Americans have.
In America it is become more and more acceptable to have premarital sex. This is very uncommon for a woman in China, and it is very unacceptable. It is more acceptable for a man obviously, because there are no physical changes that occur.
In America, if someone does something rude that is clearly from another culture, it is disrespectful to comment on it or reject them, because it is clear they do not know. I have seen this in China more than I have in America that Chinese less understanding and less relaxed than Americans. They want you to understand their culture, practice their culture, but are not very interested in your culture. I am by no means saying this is all Chinese people or no Americans do this, but it is more common in Chinese than Americans.
