In the Qin Dynasty and the early Western Han Dynasty, the prime minister was always an important position of "taking charge of the emperor and assisting him in handling state affairs". At this time, the powers possessed by the prime minister are: leading the court officials forever, presiding over the major policies of the DPRK, convening the proceedings of the DPRK, deciding the country's military and political affairs, refuting imperial edicts, appointing and removing officials, presiding over county and state plans, impeaching officials for exams, admonishing them and punishing them, and so on. Power is stronger than ever.

As the deputy prime minister, the imperial envoy is responsible for supervising officials and has an extremely lofty position, which is called "serving first". Responsibility is in charge of imperial books; Handle the throne presented to the emperor and carry out the imperial edict; Supervise all officials in the world, supervise the management of foreign governors to counties and countries, and try illegal cases of officials at central and local levels. I am in awe of the officials.

Qiu assisted the emperor in handling national military affairs, but it was only the highest honorary position of a military commander, not permanent. The emperor mainly used Qiu Lai to decentralize power to prevent the prime minister from getting his hands on the army (Qin and Han Dynasties).
