What do you think of Emperor Qianlong of the Qing Dynasty?

Emperor Qianlong has his own evaluation and is called the perfect old man. During his long-term rule, the whole Qing Dynasty maintained unity and stability and safeguarded the independence of the country. Secondly, from the comparison of historical development, China's feudal system undoubtedly began to part ways with the contemporary West during the Qianlong period. Although the feudal system did not immediately show backwardness in wealth accumulation, it was greatly uncomfortable and backward in the military, political, social and diplomatic fields in the future, which led to China's backwardness for a century. As for the feudal emperor, we can't blame him personally, but as a feudal system, we must criticize him.
