why do you think culture is important?Give me some ideas.Thanks a lot.And tell me what your culture are you most proud about

Yes,that's very important.People can get enough information about one's talent,education level and character through the culture he or she has.Especially,so far as I know,for a leader or manager of some groups,the culture of the person is significant.It shows so much for a person.
But for me,i really don't know which aspect of my culture is what i am most pround of.However,i attach much importance to that.
