What do you know about traditional Chinese culture?

Culture is a poorly defined concept, encompassing both the material and spiritual wealth of human social and historical practices. In terms of social ideology and the systems and organizations that go with it, it also encompasses many elements. With regard to traditional Chinese culture, I agree with three main categories: material and technological culture, ethical culture, and expressive culture. The first one is about science and technology, tool invention and so on; the second one is about ethics and morality, laws and regulations and so on; the third one is about literature, art, music and religion, and so on and so forth. From the hierarchy, it is "big tradition" and "small tradition", that is, the upper culture, official discourse system, and the lower culture, folk discourse system.
