Some people say that without the Manchu Qing Dynasty, China would not have such a large territory now. The reason why China has so much territory is due to the Manchu Qing Dynasty. Some people say that even without the Manchu Qing Dynasty, China would still be closed to the country, control its thoughts, be surpassed and bullied by the West, and even become a colony of the West. Some people say that it was not the Manchu Qing Dynasty that misunderstood China, but China mistook the Manchu Qing Dynasty... But what would China have been like without the Manchu Qing Dynasty? No one can know, and no one can know! Because history has happened and it cannot be repeated. History cannot be changed, but we can deduce history based on history - do not use history that has already happened to infer history, otherwise you will always be firmly trapped by history that has happened. We must look at history, evaluate history, and infer history from a developmental perspective.
