Why do most of China's classical novels focus on literati?

In the first year of Jianyuan in Liang Wudi (BC 140), Dong Zhongshu put forward in Shi Shance: "Those who are not the subjects of the six arts and masters of Confucius should try their best not to advance." In the same year, Emperor Wu of the Han Dynasty took the advice of Wei Wan, the prime minister, and deposed the sages of "Yan Shen, Shang, Han Fei, Su Qin and Zhang Yi". Wei Wan didn't directly criticize Huang Lao's words, but Dou Taihou (the grandmother of Emperor Wu), who was good at Huang Lao, strongly opposed it, and used it as an excuse to put Zhao Wan, an ancient physician who advocated Confucianism, and Wang Zang, a doctor, in prison. Although the Confucian forces were temporarily hit, in the fifth year of Jianyuan (BC 136), Emperor Wu of the Han Dynasty established the Doctor of Five Classics, and the study of Classics was more complete in the government.

In the 6th year of Jianyuan (BC 135), Dou Taihou died, and Tian Fen, who made good use of Confucianism, became the phase of Emperor Wu. Tian Fen ousted all Dr. Taichang who could not cure the Five Classics of Confucianism, excluded Huang Lao from the official school, and recruited hundreds of scholars with courtesy. This is the famous "ousting a hundred schools of thought and respecting Confucianism alone". After the exclusive respect for Confucianism, officials mainly came from Confucian scholars, who gradually developed and became the feudal orthodox people who ruled the people for the next two thousand years, becoming the most orthodox profession in China.
