How to better understand that Ming and Qing Dynasties are the prosperous times in China's history?

First of all, I think the Qing Dynasty is not a prosperous time, but the most backward period in China's history. The so-called prosperous period of Kanggan has always been controversial in China. Yan Chongnian and a professor from HKU planned to collaborate on a paper entitled "The Golden Age of China History-the Prosperous Age of Kanggan", but in the end, the expert committee failed because most of the committee were westerners, because westerners thought that Kanggan was a dark age rather than a golden age.

When talking about the Ming dynasty, the Netherlands and Britain in the west had entered capitalism, but they were still in the early stage, and their industries were basically in the primary stage. At that time, there was not even a steam engine. The Ming Dynasty belonged to the declining era of feudal society, and the Ming government was not particularly strong, especially in the middle and late period, which was often invaded by ethnic minorities. But economy still occupies a very important position in the world, not to mention agriculture. As far as handicrafts are concerned, since Huang Daopo introduced cotton spinning technology, the manufacturing technology has been greatly improved. Moreover, capitalism sprouted in the Ming Dynasty, and Jiangsu and Zhejiang provinces were extremely rich. Even ordinary people wear brocade. Holland, Spain, needless to say. Later, the strongest sun never set in Britain, and it also entered industrialization in the18th century. However, Britain has limited local resources, small land area, small population and insufficient economic aggregate. I think these have fully explained China's position in the world at that time.

The Ming dynasty was the most powerful in all fields during the first three emperors. Economically, Zheng He 7 went to the Western Seas. Militarily, all the navies in contemporary Europe can't win the Ming navy together. So, of course, the Ming Dynasty was the strongest in the world at that time.
