As the central reflection of a nation’s value, one culture not only embodies the whole of a nation’s civilization and wisdom, but also implies the genres of a nation’s development in the future. Once a nation’s culture is threatened and aggressed, a deep cultural and national crisis is brought to the nation itself, which consists of the whole meaning of cultural security of a country. The economic globalization stimulates the development of "cultural imperialism" which has become a new form of capital plunder and put threats to the cultural security of our country as well as other developing countries. Therefore, it is our task to build our system of cultural security and to safeguard our culture.
