Teaching culture is very important because it contains of worthy morale values of life. People can learn how to interact with others, to behave properly in a new society, to appreciate and understand others' culture and the way of life by knowing the culture. Besides, by learning the culture, people also will learn the language, the people, the politics, and so on. If the young generation are rich of knowledge about their own, they will appreciate and keep the culture alive, however, otherwise, the culture will die, and it will losen one history of one culture and its people. In addition, by learning culture, the young will behave properly.
I also want to say, in absorbing foreign culture, the one needs to filter it, take the good one and leaves the bad one.
