In the history of our country, the image of the king, which was once quite successful, was excessively distorted by the later winners. The most famous three are Shang Zhouwang, Wang Mang and Yang Di.

Shang Zhouwang was the first recorded emperor in the history of China who was publicly discredited by later victors, which also made people think that Shang Zhouwang was a real bad king for thousands of years. But the first person who questioned whether Shang Zhouwang was a bad king was Zi Gong, a student of Confucius.

And Zi Gong's suspicion is not unreasonable. Shang Zhouwang was a very powerful man. After he ascended the throne, he extended the sphere of influence of Shang Dynasty to Jianghuai area. Thus, Shang Zhouwang was a very successful king. However, after the establishment of the Zhou Dynasty, the King of Zhou continued to vilify Shang Zhouwang to consolidate his rule, thus establishing a fair name for himself.

Wang Mang is a very magical person in history. Some people say that he is a traveler, because many things he put forward are very similar to our current ideas. At that time, people thought Wang Mang was a usurper. At that time, the economy of the Han dynasty was already very poor, and Wang Mang's usurpation of the throne actually followed the trend. Wang Mang insisted on abolishing slavery, which was of great help to the social system at that time. But it is a pity that Wang Mang's many actions made the Western Han Dynasty on the verge of bankruptcy, offended the nobles at that time, and was finally ousted.

Emperor Yang Di Yang Guang was also a great tyrant in history, but Yang Guang did many great things in real history. Emperor Yang Guang of Yang Di perfected the imperial examination system and opened the Grand Canal, which few people could do.
