What do you mean by "three fair"?

The three most prominent official positions in ancient China. This word was already used in the Zhou Dynasty, and according to The Great Biography of Shangshu and The Book of Rites, the writers of the Western Han Dynasty thought that these three names meant Sima, Situ and Sikong (see three things). According to Zhou Li, the classical scholars in ancient China believed that teachers, teachers and Taibao were three kinds of public officials. There were no three fairs in the Qin Dynasty. At the beginning of the Western Han Dynasty, the people who inherited the Qin system and assisted the emperor in governing the country were mainly prime ministers and censors. There is also the highest military attache Qiu, but I don't buy it often. Since Emperor Wudi, influenced by Confucian classics, Prime Minister, Imperial Advisor and Qiu have been called "Three Fairs".

In order to strengthen centralization of authority, Liu Che weakened the power of the prime minister. During the reign of Zhao Kuangyin, Huo Guang served as assistant minister of General Fu. Later, important officials in power, such as Zhang Anshi, Scofield and Wang Feng, all held the post of General Fu. So the great Sima Quanling rode above the Prime Minister. In the first year of He Sui (the first eight years), He Wu's suggestion was adopted, and the scholar in the imperial examination was changed to Dasikong, and the salary of Fu and Dasikong was raised to be equal to that of the prime minister, thus establishing a three-metric system in which Fu, Dasikong and the prime minister were the three pillars. I loved Emperor Yuanshou for two years (1), and the name of the Prime Minister was changed to Da Situ, which is exactly the same as the three names mentioned in this article. And put the original Taifu and the newly added Taifu and Taibao above the three fairs, with high titles and no real power. Although there were three pillars at the end of the Western Han Dynasty, Fu was still the most important. Dong Xian and follwed, for example, both held this position and were good at politics. In the new era, the three metric systems of the Western Han Dynasty were used.

There were three officials in the early years of the Eastern Han Dynasty. In the twenty-seventh year of Jianwu (AD 5 1), it was rebuilt to Qiu, Da Situ and Gai Situ. Each of the three fairs has a history of thousands of stones, and each has dozens of people. Take Taiwei as an example. Cao, Cao Dong, Cao Hu, Cao Zou, Cao Ci, cao thief and Cao Cang are in charge of everything. Sangongfu was referred to as Sanfu for short at that time. Taiwei still ranks first in the three fairs.

Liu Xiu, Emperor Guangwu of Han Dynasty, carried out a more extreme centralization of imperial power, and did not make power belong to ministers. In name, he set up three senior officials, but the real power gradually returned to Shangshutai. The emperor, the golden palace, consorts and eunuchs changed their authoritarian power. Dou Xian and Liang Ji, consorts, are all worshipped as generals, and generals have official positions, ranking three. The three fairs not only surrendered to ministers, but also to consorts and eunuchs, and some even their confidants. According to scholars, the prime minister assisted the emperor in managing Yin and Yang, and when arranging the four seasons, both the emperor and the prime minister would blame themselves for all kinds of disasters. In the Eastern Han Dynasty, the emperor put the blame on Sangong, so whenever disasters such as floods and droughts occurred, Sangong was often exempted. Therefore, Zhong Changtong said that the three fairs exist in name only, and they are just "staff members".

At the end of the Eastern Han Dynasty, Dong Zhuo was the prime minister, ranking above the three fairs. In the 13th year of Jian 'an (208), Cao Cao went to Sangong to buy off the Prime Minister and imperial envoys, and Cao Cao became the Prime Minister himself. The three metric system, which lasted for 200 years, was implemented in the Han Dynasty and ended from then on.

Cao Wei restored the three public systems. During the Wei, Jin, Southern and Northern Dynasties, Sangong was still in the best position, and the government set up aides. However, the real power was further transferred to the Shangshu institution. In the Sui Dynasty, the three official positions were no longer open, and all the assistants were revoked, which completely became a virtual position or "upper position". After the Song Dynasty, they were often called Taishi, Taifu and Taibao, but the nature of their virtual titles remained unchanged and gradually evolved into adding officials and giving them away. Ming and Qing are the same.
