Private school came into being in the Spring and Autumn Period, and Confucius' private school was the largest and had the deepest influence. At that time, the unified slave country, the Western Zhou Dynasty, gradually declined, and the ceremony collapsed and the music was bad. From "learning in the government" to "learning in the four foreigners" It turned out that the officials of the Western Zhou Dynasty went to various vassal States to seek a way out, and the private doors and even big doctors in various vassal States needed scholars to serve them, competing to cultivate scholars, and the way out for scholars gradually widened, so the "scholar" class appeared. The cultivation of scholars has become an urgent requirement, and private schools have emerged. There are various schools in the scholar class, representing the interests of different classes or classes. In order to cultivate their own talents, various factions publicize their ideas to the rulers and ask them to adopt them in order to expand their political power. Among them, Confucianism, Mohism, Taoism and France have great influence, and each has its own advantages and disadvantages academically. Basically, the feudal emperors of past dynasties did not choose only one, but integrated the skills of each family to become emperors, serving to consolidate the feudal system and the rule of each dynasty. All four families have private schools. In the Warring States period, Qin, Qi, Chu, Yan, Han, Zhao and Wei competed for hegemony. "There is no fixed relationship between countries, and scholars have no fixed masters." The price of scholars' right to speak is getting higher and higher, the atmosphere of cultivating scholars is getting stronger and stronger, and private learning is more prevalent. The wind of "teacher" is very strong, so there are more private schools, and there has been a situation of "a hundred schools of thought contend".
