1, the country is divided, the power is divided, the war continues, and the people are miserable. For example, the Spring and Autumn Period and the Warring States Period, the late Qin Dynasty and the early Han Dynasty, the late Han Dynasty and the early Tang Dynasty, the separatist regime in the late Tang Dynasty and the late Song Dynasty, the replacement of the Yuan, Ming and Qing Dynasties and the Republic of China until the early days of the founding of New China;
2. The people suffered greatly from the wrong line, principles and policies implemented by the Central Committee. For example, in the last years of the dynasties, the taxes and corvees were imposed, the power and people were abused in the Qin Dynasty, the witch chaos in the Han Dynasty, and the ethnic division in the Yuan Dynasty. , including the Cultural Revolution in New China;
3. When foreign enemies invade, civilians suffer. After the Opium War, foreign powers carved up China, such as two Opium Wars, Russia and the later Soviet Union split and annexed our territory, and Eight-Nation Alliance invaded China, among which the period of Japanese full-scale aggression against China was the most symbolic. Compared with Japan, the Netherlands, Portugal, Britain, France, Germany, the United States, Russia and other countries, it is really dwarfed! )
It can be inferred that the so-called "dark period" includes thousands of years. In contrast, our life today can be compared with that of the Tang Dynasty! (Only in the heyday of the Tang Dynasty, there were not so many powerful countries around! ... there is still a long way to go to return to the ranks of great powers! )
