After the establishment of college students in the Tang Dynasty, until the Ming Dynasty, college students were all held concurrently by the prime minister, and their positions had no real power. It is only a generous gift for the Prime Minister to remain a college student after leaving office.

After the abolition of the prime minister in the Ming Dynasty, the cabinet college students inherited the responsibilities of the prime minister and had real power. Among them, the record of university students is the same as that of prime ministers in previous dynasties. But to master power, we must unite eunuchs, otherwise it will be difficult to implement.

Although the Qing dynasty inherited the cabinet system of the Ming dynasty, the early college students were all subject to the king's deliberation meeting and did not have much real power. Later, Kangxi gradually deprived them of the right to discuss the affairs of the king, and directly used Southern Studies to manage the country. Although the cabinet university has mastered the foreign dynasty, its power has been greatly weakened. Especially after the establishment of the military department in Yongzheng, the university students need to concurrently serve as the minister of military aircraft, which is the real prime minister, otherwise it is just an honor.
