Qianlong told Jiaqing: Let go of Hezhen, Jiaqing did not listen to persuasion, and after 15 years he began to "regret"
In everyone's eyes, Hezhen is a huge greed, ranking first in China's history. In real history, Hezhen was indeed very greedy, and there is a saying that Hezhen fell, and Jiaqing was full. The wealth of a single person can fill the treasury. Before Qianlong died, he told Jiaqing not to kill Hezhen, and Jiaqing immediately executed Hezhen after he ascended the throne, but he regretted it after 15 years.
When he was young, he was also considered to be from a famous family, but after the family's decline, he's family property was taken away. Since then, he has aspired to stand out, he is familiar with the Four Books and Five Classics, he is full of poetry, and he is proficient in Manchu Chinese and Tibetan. Speaking of Ji Xiaolan, Liu Yong and a series of assassin-headed literati, they were all dead set on the Qianlong Emperor. Qianlong, who knew the way of the imperial court so well, he was well aware of the usefulness of Hezhen for the Qing Dynasty.
The most important point is that Hezhen has no ambitions, and people who are too capable will always be wary of the imperial power and nobles, while Hezhen has his own means, although he is a big corrupt official around the emperor, but he can do not be greedy at all in terms of disaster relief funds and imperial examination funds. Because he knew where Qianlong's bottom line was. He also never cared about the military, and was able to get things done completely. This also made Qianlong trust him very much.
He knew that there was no crisis for him. And he is not only good at accumulating wealth, but also good at financial management, and his shrewdness and ability deeply convince Qianlong. Later, before Qianlong died, he also specifically instructed Jiaqing not to embarrass him, let alone kill him. However, the young and vigorous Jiaqing Emperor did not listen, did not heed the instructions of the former emperor, and as soon as he came to power, he was anxious to attack Hezhen. However, after he died, he truly regretted his behavior, when the finances were stretched to the limit, and although the DPRK and China were civil and military officials, they were unfavorable and blamed each other. He had to sigh that there was no one in the DPRK who stood up in a time of crisis like Kazuma.
