The Qianlong Emperor had unlimited scenery in his life, single-handedly created and experienced the last feudal prosperity in China, and also left many wenzhi martial arts during his reign.
However, the matter of the heir to the throne made him hurt his brain, although there were many princes, but there were not many who could inherit the Ai Xinjue Luo clan, and he could only find a big one in the short, and he reluctantly chose the fifteenth son of the emperor, Lu Yan.

This election directly led to the development of the Qing Dynasty began to show a trend of decline. Although Jiaqing also implemented a number of new policies after he came to power in order to be able to govern the court and the world, after the implementation of most policies, due to the damage to the rights and interests of the royal family and countless manchu officials, Jiaqing finally lost his courtesy.
When Jiaqing first succeeded to the throne, he was very unconvinced by the old Qianlong, and he felt that he would definitely rearrange the mountains and rivers, and the most incomprehensible thing was that when the Qianlong Emperor died, Jiaqing did not even shed a tear.
Subsequently, immediately after the death of his father, he executed the person his father trusted most, this person was Hezhen, and after executing Himan, he began to pin his ideals on the "Salty and Restoration".
01. First rectify the rule of officials
However, this reform of Jiaqing did not seem to be out of the capital, he himself was quite frugal, and he was not accustomed to the vain style of those eight flags disciples, so the Jiaqing Emperor first educated all officials and ordered them to practice frugality and do practical things for the country.
When he heard that there were many theaters and restaurants in the capital, and that he had earned countless Eight Flags disciples, the emperor could not execute all the Eight Flags disciples, and simply closed all consumption places.
02. Secondly, suppress the uprising.
The class contradictions in the country were acute, and the peasant revolt was in full swing. After the Jiaqing Emperor ascended the throne, he devoted all his efforts to encircle and suppress the great peasant uprisings in Sichuan, Chu, and Shaanxi. It is easier to command the army and severely punish the generals who are ineffective in suppressing them.
Strict military deployment, the implementation of a two-handed policy of suppression and support, and the division and disintegration of the rebel army. The policy of clearing the wilderness of the fortified walls was implemented, and the ties between the rebel army and the people were severed.
03. Finally, sever diplomacy
In his diplomatic dealings, the Jiaqing Emperor advocated the strict prohibition of opium, maintained a high degree of vigilance against the harassment activities of the British invaders along the coast, and wisely and sternly refused the British demands to help the Qing Dynasty suppress the rebel army and help the Portuguese in Macao resist the French ulterior motives.
The traditional concept of closing the country to the outside world also makes it adopt a blind rejection attitude towards foreign things. The Jiaqing Emperor, amid frequent internal strife and imminent external troubles, made every effort to maintain the stability and consolidation of the Qing Dynasty.
However, the irreversible historical development trend has made the fall of the Qing Dynasty in the last years of Jiaqing completely superficial, and it has gradually declined since then.
