Seven ministers and eight teeth are dynasties in history.

It is an anecdote during the Yongzheng period of the Qing Dynasty.

In order to compete for the throne, Yongzheng absorbed a large number of talented people in the rivers and lakes for future use. After Yongzheng acceded to the throne, fearing that others would not listen to him, he set up secret detective teams in various provinces and made great efforts to rule by secret agents. Infernal affairs is everywhere.
