On the third day of the first lunar month in 1799, the Qianlong Emperor died, and the Jiaqing Emperor ordered the funeral of The First Emperor, but just ten days later, on the thirteenth day of the first month, the Jiaqing Emperor suddenly declared the twenty major sins of Hezhen, ordered the raid on the house, and copied 800 million taels of silver, that is, the so-called "Hezhen fell, Jiaqing was fed". On the eighteenth day of the first month, Jia Qingshi and Yan committed suicide in prison.

He Yan's death penalty deserved it, but there was a counterintuitive point: after Qianlong passed on the throne to Jiaqing, he became emperor for three years and sheltered He Yan for three years, but since Jiangshan was sooner or later the Jiaqing Emperor, it was reasonable to say that He Yan was a wise man, why did he not take the opportunity to curry favor with Jiaqing in these three years?
The story of the "Nine Sons And Nine Sons And Concubines" must be known to everyone, and the Yongzheng Emperor at that time learned the lessons of the Nine Dragons Conquest in the Kangxi Era and adopted the method of secretly establishing a reserve. The so-called secret reserve is to write the heir on the holy will, and then put it in duplicate, one behind the "Zhengda Guangming Plaque" in the Qianqing Palace, and one copy of his own collection, declaring that the prince of the group has been established and determined. Once the current emperor dies, then the minister will take out two copies of the Holy Will, and after merging them into one, the new emperor can be proclaimed.
After Qianlong succeeded to the throne, he also adopted this method of secretly establishing reserves. In 1773, Qianlong secretly made his fifteenth son Yongyan crown prince, and no one except Qianlong himself, including Yongyan and Heyan, was known. It was not until 1795, when the minister took down the secret will after the Zhengda Guangming Plaque of the Qianqing Palace, and compared it with the secret instructions collected around Qianlong, people knew that Yongyan was the crown prince.
Therefore, even if Hezhen wanted to tie the knot, at least until Jiaqing succeeded to the throne, he would not be able to tie the knot. After all, Washu had no idea who the future emperor would be. So since you can't tie the knot before succeeding to the throne, why don't you stammer after the succession? After all, Qianlong had been emperor for three years, and during these three years, although Jiaqing was not in power, he had already ascended the throne after all.
First of all, after Qianlong Zen let Jiaqing, it was still in power, and Jiaqing could only handle some political affairs in the corners and corners. After Qianlong abdicated, he still lived in the Yangxin Hall to control the government, and on the 19th day of the first month of 1796, Qianlong summoned the envoys of the subordinate state and bluntly said, "Although the government is returned to the emperor, I still handle major affairs." Moreover, Qianlong often went to the court to preside over the government, and He Yan stood next to him and Jiaqing, and Qianlong was the one who really made up his mind.
Therefore, Qianlong controlled the government, controlled Jiaqing, and also controlled the fate of Hezhen, which made Qianlong dare not betray Qianlong to curry favor with Jiaqing. Secondly, He yan is a vested interest, and he is also blindly confident in himself, thinking that he can escape jiaqing's hands.
After Qianlong Zen ascended to the throne of Jiaqing, he was not willing to delegate power, and often participated in court meetings, and ordered He Yan to stand next to him and Jiaqing when he went to the court. Because Qianlong was already more than 80 years old at the time, others could not understand what Qianlong said, and only He yan, who was often with Qianlong, could understand. Therefore, He yan was like a regent, he "listened" to Qianlong's speech, and then made his own judgment, thus controlling the government, at that time the Qing people called He yan "second emperor", as for Jiaqing on the side was only "three emperors".
Therefore, He Yan was very confident in himself, believing that even after Qianlong's death, his own family could still control the imperial court, and Jiaqing had no choice. Therefore, He yan and Jiaqing are naturally opposed in terms of power interests and cannot be integrated.
What do you think about that?
