I'll answer this question. I feel that your question is quite novel. Ask Liu Che, emperor of the Han Dynasty, and Yang Guang, emperor of the Sui Dynasty, what are their similarities. Supposedly, these two emperors have nothing in common, because Emperor Wu of the Han Dynasty was a brilliant emperor in ancient China. During his reign, he crusaded against Xiongnu five times, relieved the threat of northern minorities to the Central Plains Dynasty, and made great contributions in the history of China, so his reputation even surpassed that of Liu Bang, the founding emperor of the Han Dynasty. As for the words of Emperor Yang Di, we all know that he is a tyrant. Under his auspices, the once brilliant Sui Dynasty II passed away, which is very regrettable.
Regarding the similarities between the two of them, it should be said that they are both emperors first. Second, both of them are brilliant, not to mention the brilliant talent of Emperor Wu of the Han Dynasty, who also made some remarkable historical contributions. Yang Guang, Yang Di of Sui Dynasty, was actually a brilliant emperor, because he changed his career at the beginning of his reign. He also wanted to do something, but his shortcoming was that he did not sympathize with the people's strength, and then he dug a canal to build the eastern capital. There are too many projects that consume manpower and material resources, including the three signs against North Korea, which finally led to the tragedy of national subjugation.
