He Yan can be said to be the favorite of the Qianlong period, and even the relatives of the emperor at that time did not get favored by He Yan, and wang ye, belle, and the prince sometimes had to beg him. The Qianlong Emperor sometimes didn't see Hezhen for a day. From a palanquin to a generation of ministers who have power to the opposition, it is also rare in ancient and modern times. Of course, Washu is also very good at being a person.

He Yan often traveled with the Qianlong Emperor, Qianlong's favorite ten princesses also often dressed as women to follow, the ten princesses saw him and called him Zhangren, and He Yan was also very good at flattering, what the ten princesses liked, he Yan bought her what, the princess loved, and He Yan would offer anything. It is said that once, the Tenth Princess accompanied the Qianlong Emperor on a trip, and went with Yan. Came to a market, the market has a clothing shop, the clothing shop has a beautiful red coat, the tenth princess said that this dress is good, and Washu heard about it and immediately bought it and gave it to Washu. It is said that twenty-two gold was spent (twenty-two gold is about 1,000 grams, that is to say, two catties of gold, if it is more than 400,000 yuan according to the current market price). Later, the Tenth Princess married Hezhen's son Fengshen Yinde.
Of course, He yan's flattery and flattery were only in front of Qianlong, and he was not so "kind" in front of others. Pretending to be a grandson in front of the Qianlong Emperor is a grandfather in front of those ministers. Most of the people in the court were his henchmen, and many people relied on him. Of course, He Yan was also a very rich lord, in addition to doing business himself, he could also embezzle and accept bribes, and it was said that he was richer than Qianlong, which was really a veritable wealth to rival the country.
His family's wives and concubines, the number of beautiful concubines in the family is uncountable, in addition to these there are general lackeys. The so-called one person gets the Tao, and the chicken and the dog ascend to heaven. These dog-legged people could not be lawless and ran amok in the capital. It is said that once when The Imperial Historian Cao Xibao and Liu Quan, a slave of the Yan family, Qianlong sent someone to investigate, but the investigating officials said that Cao Xibao framed Liu Quan, and as a result, he was punished. Considering that a dynasty imperial history could not participate in the hezhen to get a domestic slave, it can be seen how powerful he was.
However, he was also afraid that it was said that once Qianlong wanted to abdicate and let his son Yuanyan inherit the throne, which almost scared He Yan to death, and he tried to dissuade him, but the Qianlong Emperor tried to pass the throne to his son. Although the throne passed to his son, the power was still in the hands of Qianlong, and He Yan put his mind at ease again.
However, the good times did not last long, and three years later the Qianlong Emperor died, and the good life of Hezhen was over. On the fifteenth day after the death of the Qianlong Emperor, the Jiaqing Emperor (qianlong's fifteenth son) killed Hezhen and confiscated his family property. It is said that 820 million silver was found. (At that time, the annual revenue of the Qing Dynasty was about 5,000 taels.)
