The word "nave" originated in the Tang Dynasty, and the prime minister worked in the yamen of Zhongshu Province, so the prime minister in the Tang Dynasty was nicknamed nave. After the Ming dynasty, the cabinet college students were called the central hall.

The evolution of nave authority. Until the Ming Dynasty, this system had undergone earth-shaking changes. Zhu Yuanzhang, the emperor of Ming Dynasty, officially abolished Hanshu Province by using the case of Prime Minister Hu, and took all the rights of the country into his own hands.

However, not all the emperors of later generations were as diligent as Zhu Yuanzhang, so gradually there was a cabinet college student to take care of the emperor's political affairs. Although the nominal "prime minister" of the cabinet university was severely weakened, it was still called "main hall" in later generations.

Unfortunately, these nominal "stalls", the so-called cabinet junior college students, have only five qualities. Although there is some embarrassment, it has gradually risen to a position consistent with power. After the Qing Dynasty, the cabinet college students continued to be in charge of state affairs, and their status gradually improved, becoming a civilian with one product and two products and becoming the norm.

Of course, the name "main hall" continues to be used by Cabinet University. The awkward position of the "middle temple". Before Yongzheng ascended the throne, the cabinet college students could barely be called "prime minister", but after Yongzheng established the "military department", the power of the cabinet college students was weakened again. Although it was still called "nave" at that time, it was seriously out of name.

Although Liu was honored as "Liu" and barely called "Prime Minister of Thick Ink", in fact, only officials who were both cabinet university students and military ministers were qualified to become real "Prime Ministers" in this period. Just like Liu Yong's father, Liu Tongxun, who is highly regarded, is the real prime minister.

Nave is not good at this because Nave is already a big official in essence, and many of them are officialdom leaders. Although he is a leader, this leader is not easy to do because he is sandwiched between the emperor and the whole officialdom. Sometimes the emperor and officialdom have contradictions and need these naves to reconcile.
