When Qianlong was 84 years old, there was another uprising in Miaojiang, and after the imperial court had a hard time quelling the rebellion, Qianlong gradually became tired of political affairs, and he decided to take the throne and enjoy the blessings of being the emperor of Taishang. He tried to stop Qianlong from taking the throne, but Qianlong did not listen to him. In the first month of the following year, at the gate of the Qianqing Palace, hundreds of officials knelt down to listen to the announcement, and Qianlong officially announced to the world that Zen was located for his son Jiaqing. At this time, at the age of 46, he continued to serve as the minister of the Upper Study and the Military Aircraft Department, and still received the favor of the Emperor Taishang.
Although Jiaqing was proclaimed emperor, he still paid tribute to his father every day in the major affairs of the imperial court, and sometimes his suggestions were interfered with by his father, and He yan was sandwiched between father and son, often assisting Qianlong to reprimand Jiaqing. Jiaqing was very upset in his heart, and even sometimes, He Yan directly bypassed him as the emperor and reported directly to the Emperor Taishang, causing Jiaqing to be very passive. Once, the prefect of Hangzhou broke the law, and He Yan accepted a bribe and directly interceded with Qianlong, and Qianlong summoned Jiaqing to come and ask him to exempt the prefect. Although Jiaqing agreed, after investigation, this prefect was extremely evil and did not meet the conditions for pardon, so there was no pardon. He Yan met with the Emperor Taishang again and said that Jiaqing had not yet released the prefect. Qianlong was furious and directly rebuked Jiaqing, who was as earth-colored as he was, and he quickly prostrated his head and confessed his mistake, although he let go of this prefect, but his heart was very hateful and hateful.
Since then, Jiaqing has learned to be patient, and he is also very respectful to adults, often thinking of himself as a junior. Paralyzed he, and after three years, the Emperor Taishang died, and he immediately ordered Hezhen to go to guard the spirit, and on the grounds that the former emperor trusted Hezhen the most, he could not stay in the spirit shed for more than ten days, which was a complete tie to Hezhen. During this period, Jiaqing joined forces with Wang Jie, the chancellor of the study, Zhu Gui, the teacher, and others to secretly investigate and investigate, and immediately after the evidence of the crime was collected, he immediately ordered the raid on the house and arrested. This powerful Qing Dynasty minister, from being found to giving death, was completed in just 5 days. Many of Hezhen's colleagues and protégés did not have any psychological preparation for the fall of Hezhen, and even had no time to discuss countermeasures with each other.
At that time, the chancellor of hezhen, named Wang Jie, when he raided the hefu, except for the ten princesses (he yan's daughter-in-law) mansion was not raided, the mansion of the two brothers and sisters copied a total of 1 billion silver, gold and treasures. At that time, the annual income of the imperial court was only 70 million, which was equivalent to the revenue of the National Treasury of the Great Qing Dynasty for 15 years. Jiaqing hated this, and did not expect that the imperial court was tightly financed, and He Yan had so much property. And in Hefu copied out a large number of letters with the national henchmen, Jiaqing immediately ordered the arrest of Hezhen's henchmen, and the list listed by Wang Jie at that time totaled 3,000 people who were "lishang" with Hezhen, or the protégés of Hezhen, and the number was almost all over the government and the opposition.
At this time, an 80-year-old old minister came with a cane and trembling, and When Wang Jie and other ministers saw this person, they immediately performed the ritual, and this person was Liu Yong, who was the former Shangshu of the Punishment Department and now the Crown Prince Taibao. During the Qianlong period, the prestige of Liu Tongxun and Liu Yong's father and son was very high. Liu Yong said to Jiaqing: "Long live, Wei Chen and He Yan have no friendship, nor have they come to intercede for him, but He Yan's henchmen are all over the world, and if they are eliminated one by one, they are bound to cause turmoil." The White Lotus Sect and other mobs will definitely take the opportunity to riot, and I am afraid that it will be difficult to clean up at that time. Jiaqing listened to Liu Yong's words, thought about it for a while, and ordered Wang Jie to burn all the letters exchanged with He yan and tell the world that anyone who had bribed He Yan would not be blamed for the past as long as he had repented from today onwards. At that time, if he did not learn the lesson of Hezhen and continued to violate the laws of the land, he would be severely punished. In this way, Liu Yong's words saved more than 3,000 people.
Although most of these 3,000 people were corrupt officials, Jiaqing put Jiangshan Sheji as the most important thing, and in order to avoid causing turmoil, he did not kill the ring, and Liu Yong's words were indispensable.
