Cao Xueqin is a spy of Kangxi. Why can't Yongzheng catch him?

Cao Xueqin is a spy of Kangxi, and Yongzheng can't help him. Mainly because after Yongzheng came to power, he formulated many policies for the national finance, and Cao Xueqin's family owed a lot of money to the country, so Yongzheng copied Cao Xueqin's family.

Speaking of Cao Xueqin, many people are familiar with it. He is the author of four classical novels A Dream of Red Mansions, and Cao Xueqin's family was once very powerful. Cao Xueqin's ancestors were originally prisoners and slaves of Nurhachi. Later, Cao Xueqin's great-grandmother became the wet nurse of Emperor Kangxi and brought him up, so for Emperor Kangxi, the wet nurse was her own relative, in order to repay the wet nurse's kindness in raising him. After Emperor Kangxi ascended the throne, he also took special care of the wet nurse family. Cao Xueqin's great-grandfather was named Cao Xi, and Emperor Kangxi put him in charge of a very important department, Jiangning Weaving, which shows that King Kangxi had great trust in Cao Jia.

It turned out that Jiangning weaving changed its management staff once a year, and Emperor Kangxi directly made the Cao family hereditary, but the fate of the Cao family was not very good. From Cao Xueqin's father's generation, they all died young. Later, Emperor Kangxi couldn't bear to see that the wet nurse's family had no heir and thought of many ways, but even so, the Cao family slowly declined.

It was not until Yongzheng succeeded to the throne that the deficit of the state treasury was first dealt with. At this time, it was found that Cao Xueqin's family also owed a lot of money to the state treasury, because Emperor Kangxi often lived in Cao's family when he was on a southern tour, and the king's trip was vast and costly. Therefore, the Cao family owed a lot of money to the country in order to receive the king and expand the palace, but with Cao's ability, it could not afford it at all. Yongzheng copied Cao Xueqin's home to show his justice in law enforcement, but he didn't have too many entanglements with Cao's family, and some even promoted them to official positions.
