As the political adviser and the highest staff of the emperor, the cabinet college students were responsible for drafting imperial edicts and reviewing the memorials, and their authority was roughly equivalent to that of the Tang Dynasty in China. The right of the cabinet college students to "draft a ticket" is the right of the calligraphers in the Tang Dynasty to "participate in the discussion of chapters". The rank of cabinet university students is lower than that of China calligraphers in Tang and Song Dynasties, but at its peak, their power is equivalent to that of China calligraphers in Tang and Song Dynasties.
