What are the cultural concepts that China should abandon?

Our history teacher said that the biggest drawback is the feudal system and feudal thinking, which has bound the talents, and the Ming Dynasty's imperial examinations and the eight-legged essay were influenced by the feudal system. For example, in The Analects of Confucius, there is the saying that "The teacher must follow the teacher's steps, and the student must follow the teacher's tendency", which means that the student must obey the teacher absolutely. Chinese traditional culture requires absolute obedience: "The king is the program of the minister, the father is the program of the son, and the husband is the program of the wife", which means absolute - right - obedience - from! -This traditional culture requires absolute obedience! This kind of feudalism led to the "old-fashioned" thinking of the Chinese people, and "superstition" was also derived from this, that is, the people absolutely obeyed the will of the gods. (Yuan Shikai used Confucius' "absolute obedience to the monarch" to consolidate his presidency, which is why he honored Confucius and restored the past)

Ritualism, that is, some of the red tape, is also about absolute obedience and the three principles and five rules.
