To sum up, private schools in the Spring and Autumn Period and the Warring States Period have the following characteristics: free teaching, each with its own characteristics. Most of the founders of private schools are prestigious academic dog teachers in Gao Zhuo. The teaching contents, methods and principles are all drawn up and innovated by ourselves. If the educational viewpoint is reasonable, it can be established as a teacher. The History of Art and Literature in the Han Dynasty records that Confucianism "wandered between the Six Classics, paid attention to benevolence and righteousness, and the ancestors recited Yao and Shun, charting civil and military affairs". Taoism emphasizes "self-discipline" and "the skill of the monarch". Yin and Yang stress astronomical phenomena; Mohism advocates frugality, benevolence, Shang Tong and destiny, and attaches importance to the teaching of applied science and technology; On the other hand, legalists domesticate scholars with the art of criminal names. All these show a characteristic of private schools. It is the basis of various schools of thought. During the Spring and Autumn Period and the Warring States Period, most famous thinkers gathered their disciples to give lectures, and private school masters also gave lectures mainly on their own knowledge. "Lu Chunqiu Persuasion" said that "the teacher teaches, and does not dispute the dignity, but seeks the Tao." That's what I said. Private schools have become forums and bases for various schools to publicize their ideas and "argue". Generally speaking, the more distinctive a school's theory is and its social prestige is, the more students it attracts, and the more students it attracts, the more influence it can expand. The combination of thinkers and educators is one of the main characteristics of private schools in this period.
