In order to further ease the contradictions between the Manchus and the Han, Kangxi further encircled the scholar class in Jiangnan. From the 23rd to the 46th year of the Kangxi Dynasty, he went down to Jiangnan six times.
Kangxi went down to Jiangnan six times and actually lived in the Cao family four times. Why did Kangxi live in the Cao family? Because Cao Yin's mother was Kangxi's nursing mother, Cao Yin and Kangxi were milk brothers.
Kangxi was very kind to Cao Yin, and at the age of sixteen, he let Cao Yin enter the palace and was responsible for his car driving honor guard, and after sixteen years of training, let Cao Yin serve as a weaver in Suzhou.

After another three years as Jiangning weaving, in the Qing Dynasty Jiangning weaving is a big fat difference. It can be seen that the relationship between Kangxi and the Cao family, as well as the importance attached to the Cao family.
Although Cao Yin had a good job, when the Kangxi Emperor came, all the expenses had to be paid by the Cao family. Tossing once is OK, this toss four times, directly let the Cao family can not make ends meet, had to borrow money to live.
The Kangxi Emperor also knew that the famine pulled down by the Cao family was very large, and he gave the Cao family a fat and part-time transport, anyway, turn a blind eye, you have nothing to catch some oil and water.
When the Yongzheng Emperor came to power, why did Yongzheng raid the Cao family? First of all, when the ninth son took the wife, the Cao family bet on the wrong treasure, stood on the wrong team, and lost their political backing.
After Yongzheng came to power, he wanted drastic reforms. It is necessary to solve the empty treasury, the use of troops in the northwest, and the natural disasters of several provinces, many imperial relatives and state relatives have been pursued, and the Jiangning weaving Cao family, as the richest man in Jiangnan, is doomed.
In the fifth year of Yongzheng, Cao Xueqin's father Cao Yan was imprisoned for having a huge deficit, and the Cao family wanted to sell their property to fill the deficit. However, someone impeached the Cao family for transferring property.
Yongzheng had a special atmosphere, and in the sixth year of Yongzheng, he began to thoroughly raid Cao Mansion. After Cao Xueqin's house was raided, only 60,000 taels of silver were confiscated. The great Cao Mansion has such a little money, and no one believes it when he says it.
This money is still money in the homes of ordinary people, which is too little for Yongzheng. The Yongzheng Emperor originally wanted to make a big profit, but after seeing the list, his heart was cold and he was too disappointed.
The Jiangning weaving Cao family, the richest man in Jiangnan, has since been utterly defeated, and after Yongzheng raided the Cao family, it did not uproot and retain the Cao family's residence and slaves in Beijing, so that Cao Xueqin had a basic living security.
After the Qianlong Emperor came to power, he did not let the Cao family fill the deficit. Cao Xueqin served as a pen-paster in the Ministry of Internal Affairs, and at this time Cao Xueqin began to write "Dream of the Red Chamber", and a great masterpiece was born.
