The prosperous period of Kanggan was the last one in the history of China, and it was a relatively prosperous period in China. In its heyday, Kanggan was ruled by emperors Kangxi, Yongzheng and Qianlong. Yongzheng reigned for the shortest time, only thirteen years, and Kangxi Qianlong reigned for sixty years, which was also one of the longest reigning emperors in China history. Their achievements are different, including the best period of national conditions and the crisis in its heyday.

Kangxi is one of the most outstanding emperors in the history of China. He ascended the throne at the age of eight and came to power at the age of sixteen. The most famous event he did was to outwit Ao Bai, consolidate the imperial power, recover Taiwan Province Province, expand the territory of the country, and greatly safeguard the rule of the Qing Dynasty with the victory of the Russian War. But in his later years, officials were seriously corrupt and the state treasury was empty. In addition, the heir has not been established, so there has been a phenomenon of nine sons taking the office, which is also a historical comparison.

Yongzheng has always been a controversial emperor in history. Some people think that Yongzheng's accession to the throne changed Kangxi's legacy, while others think that Kangxi always wanted Yongzheng to ascend to the throne, but there was no decree. When Yongzheng ascended the throne, the treasury of the Qing Dynasty was empty, and Kangxi left him with a mess. Officials began to slack off and corruption was serious. However, after Yongzheng ascended the throne, he carried out reforms such as streamlining institutions and rectifying official management. Thirteen years in office, rich second generation. ?

When Qianlong ascended the throne, because of the considerable treasury left by his father Yongzheng, Qianlong was able to do a big job and bring the Qing Dynasty to the peak. However, in his later years, he began to crave pleasure. He spent a lot of money on several trips to Jiangnan, and the state treasury gradually became empty, leaving a mess for his son Jiaqing. So among san huang, Kangxi made the greatest contribution, followed by Yongzheng, and then Qianlong.
