Almost every dynasty is doomed, and there will be a period of chaos, such as the early Warring States, the peasant uprising at the end of Qin Dynasty, the scuffle between the three countries at the end of Han Dynasty, and later the five lakes and sixteen countries. But the most chaotic period was from the Taiping Rebellion to the Republic of China and then to the Japanese invasion of China in the late Qing Dynasty.

The previous wars were only internal struggles of the Japanese people, but in the late Qing Dynasty, it was a large-scale invasion by foreign enemies, such as Eight-Nation Alliance's invasion of Beijing, "burning the Yuanmingyuan", the "Russo-Japanese War" in the northeast, and finally the Japanese aggression almost destroyed our country.
