1. What I want to say is 1 this person, you should all be familiar with him. He is Zhao Kuo, the protagonist often mentioned in our primary school textbooks. Zhao Kuo could read many famous books when he was very young, even his father Zhao She couldn't beat him. So he was very confident when he was a child. As he grew older, he read a lot of art books and learned a lot about war. But in the end, due to lack of actual combat experience, Zhao finally lost. Therefore, although Zhao Kuo could read all the books about war, he was finally asked to lead a group of soldiers to fight because he had no real combat experience. There is still a big gap between reality and ideal state, which can be said to be a classic example of scholars' mistakes in their country.
2. Zhu Speaking of Zhu, many people will think, how can it be Zhu? As an outstanding scholar who spread Chinese Confucian culture in Tang and Song Dynasties, how did Zhu become a scholar who brought disaster to the country and people? Although Zhu made a great contribution to the inheritance of Confucianism in China, it was precisely because of this that Confucianism prevailed in the Song Dynasty, which made Confucianism not well suited to the national conditions of the Song Dynasty at that time, which led to the weakness of the whole country and no one could stand up in time to help the Song Dynasty solve the crisis of national subjugation. Therefore, it is precisely because Zhu created an inappropriate theoretical theory at an uncertain time that later scholars were completely imprisoned by Confucianism and could not open up new ideas, which led to the lack of their own thinking and ignorance of reading all their lives.
Generally speaking, there should still be many examples of literati committing treason, because in the past dynasties, many of those traitors were senior intellectuals, but they did not use their knowledge to help the country become richer and stronger, but used their own culture to defraud the emperor's trust to satisfy their own selfish desires.
