Household registration reform

In the seventh year of Kangxi (1668), the compilation of yellow books was stopped, and the annual increase and decrease of fixed-mouth books were formulated and sent by various localities, and books were compiled every three years.

In the fifty-first year of Kangxi, Emperor Kangxi felt that the existing taxes were sufficient and implemented the policy of "prosperous time breeds population and never increases taxes". This is a major turning point. For the first time, household registration is completely decoupled from taxation. During the Yongzheng period, the poll tax was completely abolished and only the land tax was collected, which completely separated the household registration from the land.

Cut off Ao Bai.

In the eighth year of Emperor Kangxi (1669), Emperor Kangxi conspired with a near minister, Suodetu, to control Ao Bai's cronies (mainly military generals and police backbones) in Beijing, and then arranged for them to master the command of the garrison in Beijing. When Ao Bai entered the DPRK, Kangxi secretly ordered the teenagers in front of the imperial court to take him alive and put him in prison (Buku is a wrestling game of Manchu), and announced 30 counts of Ao Bai's crimes, which should have been dismissed and beheaded, but Emperor Kangxi saw his past merits and saved himself from death. With the fall of Ao Bai, Ao Bai's interest groups were also destroyed. This process did not lead to military bloodshed or major social unrest. Therefore, some people commented on Kangxi's handling of the Ao Bai case and said, "It is unbelievable to be quiet and do everything except evil."

Draw a map

1680, Kangxi organized western experts and scholars, spent 10 years drawing the best and most scientific map of China in the world at that time, and published his own scientific paper "Trigonometric Algorithm Theory" [2].

Compile books

Organized and compiled books such as Integration of Ancient and Modern Books, Quantang Wen, Kangxi Dictionary, and Lvliyuan [2]. I personally wrote a collection of scientific works, which is a collection of things in my leisure time [2].
