Why do some people on the Internet say that the prosperous time of Kanggan is a fake and a joke? But I watched the video that the Qing economy rose to the first place in the country during the Qianlong period of Yongzheng! 1652, Shunzhi 9 years, the total population of the country is 14483858. 10 years ago, the population at the end of the Ming Dynasty exceeded 100 million.

Where are the 90 million Han people who disappeared? Died by the butcher's knife of Manchu Tatars.

It has a vast territory with a population of less than15 million. Under such a premise, as long as the so-called "national peace and security", it will naturally be touted as "prosperous times"! ! !

Another example is the rule of Zhenguan: the population dropped from more than 50 million in the Yang Guang period to 30 million in the Li Shimin period. The disappearance of nearly half of the population means that nearly half of the cultivated land is ownerless. Therefore, during the period of Li Shimin, the grain price reached the only lowest point in China's history: four to five pence per barrel (this is the grain price in Chang 'an, which is cheaper in the county).
