There are many records about monarch education before the Western Zhou Dynasty in Confucian classics. For example, emperors, governors and their successors, governors and princes all have officials who specialize in teaching, such as "teachers", "fu" and "Bao" in the Spring and Autumn Period and the Warring States Period. Although the world is in turmoil and official studies are declining, some princes still attach importance to the education of princes. Wang Banshen (600 ~ 560 BC) of Chu * * * once reviewed his young and early heirs, and "failed to learn the lesson of teacher protection", which led to the defeat of Yanling (now Henan). The state of Jin set up "officials" to teach the children of official positions; At least in the middle of the Warring States period, the State of Qin had set up officials to protect Fu. It can be seen that Mr. Bao's teaching has institutional origins. Politicians in the early Han Dynasty paid special attention to the education of the prince. Jia Yi pointed out: "The life of the world depends on you; The goodness of the prince lies in early warning and choosing left and right. " Regard prince education as the premise of world stability. He also listed the specific contents of prince education in detail, including canon, literature, rites and music, morality, professional skills and many other aspects. Chao Cuo also suggested to Emperor Wendi that "the technique of selecting saints can be used by both the Pope and the Prince". The vast majority of emperors in the Han Dynasty, whether in the prince's stage or after they ascended the throne in their childhood, all had the experience of receiving education.
