What does ancient Confucianism include?

Confucianism was founded by Confucius, a thinker at the end of the Spring and Autumn Period, and has gone through nearly 1700 years of China civilization history. Confucianism founded by Confucius has formed a complete ideological system on the basis of summarizing, generalizing and inheriting the traditional culture of respecting relatives in Xia, Shang and Zhou Dynasties. During the Eastern Zhou Dynasty, China society was in an epoch-making historical change. The royal family declined in the Zhou Dynasty, and the feudal patriarchal hierarchy was greatly destroyed. Feudal lords fought for hegemony and social unrest. At this time, intellectuals representing the interests of all walks of life are extremely active and become an important social force. They have stepped onto the historical stage, written books and put forward solutions to practical social problems, forming a prosperous situation in which a hundred schools of thought contend. Among them, Confucianism, Legalism, Taoism and Mohism have the greatest influence. They each designed a set of plans for the emerging landlord class to end the separatist regime and realize reunification, which laid the foundation for the choice of social governance ideas after Qin and Han Dynasties.
