The Qing Dynasty has always been a controversial dynasty, and if there had been no Wu Sangui's defection at that time, perhaps the Qing Dynasty would not have existed. But history is already a fact, and now it can only be learned from history. The change of dynasties is already a very ordinary thing in China, and perhaps it is also a way to promote social development. In The history of China, there are countless dynasties, and the emperor is also a big grasp. But there are very few who can be called accomplished. In addition to the Qin Emperor Han Wu and Tang Zong Song Zu in a poem, who else can say about their great achievements? If there is, Qianlong should count as one.

Qianlong ascended the throne as emperor at the age of 25, and was valued by his grandfather Kangxi at an early age, allowing him to study and live in the palace. Qianlong Hongli should be the last famous emperor in China's feudal dynasty. He reigned for sixty years and ruled the Qing Dynasty for sixty-three years. The greatest merit of Hongli's reign was to reach the peak of the Qing Dynasty's Kangqian dynasty and further realize the multi-ethnic unity of China on the basis of his grandfather and father. On many occasions, the world's money and grain were exempted, the burden of peasants was reduced, agricultural production was protected, and the national treasury was increasingly enriched; the Qing Dynasty's territory was the largest in quelling the border rebellions, perfecting Tibetan rule, and unifying Xinjiang.
Now let's talk about the three major records he left to future generations, which reflect the glory of the Qing Dynasty under his rule from the other side, but also see the future development of the Qing Dynasty.
One: His reign can be said to be the first in the world. As the longest-lived emperor in Chinese history, he began to take power at the age of 25 and did not hand over the emperor's throne until sixty years later, and it is estimated that his sons could not wait, but this does not mean that his time has passed. Sixty years of power did not satisfy him, and after more than three years as emperor, he still exercised the highest power of the country. Therefore, Qianlong's reign lasted for sixty-three years, and there was no one in the world who lasted longer than him.
Second: During his reign, he maximized the territory of the Qing Dynasty. In order to consolidate the rule of the border, Qianlong repeatedly suppressed the border areas. He stressed that war should be in line with the royal way, and that it is necessary to fight against internal chaos and violence to ensure the country's long-term peace and stability; for remote areas and foreign countries, "intimidate and intimidate," that is, use force to deter or if necessary, send troops to requisition, resist foreign insults, appease the borders, and safeguard the unity of the country's territorial and sovereignty. He repeatedly stated that his "ten perfect martial arts" were not an act of exhaustive military force, otherwise it would not ensure the community of Jiangshan and consolidate the situation of great unification that his father and ancestors had founded. Hongli flourished in martial arts, made great achievements in quelling rebellions in the border areas, maintained the unity of the country and expanded the territory, and improved the rule of Tibet, occupied Xinjiang, and officially incorporated Xinjiang into the territory of China, thus maximizing the territory of the Qing Dynasty.
Third: After the maximum rights are reached, they begin to enjoy. In the later period, he also began to learn from his grandfather to go down to Jiangnan, but instead of micro-serving private visits like Kangxi, he was exceptionally high-profile, thinking that he had made such a great contribution to the Qing Dynasty, he began to make great achievements and began to build a large number of civil engineering. After six trips to Jiangnan, the country's manpower and financial resources were consumed, many officials also took this opportunity to embezzle and accept bribes, and the imperial court began to become corrupt, and the entire Qing Dynasty began to decline from the prosperous era of Kangqian.
At the same time, the Qing Dynasty's closed-door policy also reached its peak after Qianlong, but at that time, the Western countries had begun the industrial revolution, and the Qing Dynasty regarded their science and technology as "strange tricks and tricks", blindly only knowing how to strengthen the imperial rule, which eventually led to China's science and technology becoming more and more backward, and The emergence of China's century-old shame.
