Reading & gt notes, why did Guan Gong read Chunqiu?

I suddenly had an idea today. I read Zuo Zhuan because I am not satisfied with my reading habits in the past ten years. Many books are just general, and I don't need every book to be like this. But this is my recent time, and I want to have a systematic summary of China's ancient classics, so as to clear my chaotic brain. I want to see the charm of the words of the sages. But in the process of reading, I have a new idea. And when I didn't delve into it, it did change. At first, especially in the first chapter, I really felt this way again. Because, this chapter is the place I remember most clearly when I read Zuo Zhuan before, and it is also the chapter I agree with most. However, at the end, I began to have great differences with Zuo Qiuming's ideas and comments on some of his characters. According to legend, the art of war of Emperor Taizong of the Qing Dynasty is a Romance of the Three Kingdoms, a novel adapted from history, which contains great art of war. The Three Kingdoms are famous troubled times in the history of our country. Heroes of all walks of life show their magical powers, and good generals and heroes emerge one after another, and their strange tricks are staggering. Guan Gong is one of the representatives of this era. But Guan Gong couldn't understand The Romance of The Three Kingdoms. Maybe he read Zuo Zhuan for another purpose. The Spring and Autumn Period and the Warring States Period are also famous troubled times in China. How to survive in troubled times is the most critical. When Guan Yu and Liu Bei conquered the world, they always drifted around at first. Running around. In the early days of the Three Kingdoms, Guan Yu was just a valiant soldier and didn't show much talent. Maybe there is no chance. But Liu Bei used Guan Yu only for his bravery and didn't see his plan. Guan Yu passed five passes and beheaded six generals, and read the Spring and Autumn Period under the moon. At that time, he was desperately fleeing. Reading Spring and Autumn Annals is not necessarily learning Confucianism, but more likely he is creating his own art of war. During the Spring and Autumn Period, many military strategists' thoughts were formed at this time. This era is even worse than the turmoil in the Three Kingdoms and the demand for political power. Many classic battles and strategies are models for future generations to learn, which can be said to be a book comparable to The Romance of the Three Kingdoms. I study in peacetime.
