It is indeed an unchanging truth to read history to make sense of it. Among the ancient books, "Zizhi Tongjian" is one of the best. Since the completion of this masterpiece by Sima Guang of Song Dynasty, how many generations of Crown Princes were required to read "Zizhi Tongjian". To this day, this book has an important role to play. It teaches us the truths of faith, wisdom, courage and perseverance. Here, I'll pick the one I feel most deeply about. During the reign of Emperor Wu of the Han Dynasty, Huo went to the right place as a young man and became a general. He was the Hussar General of the Han Dynasty, with great achievements, and was a leader in killing the enemy. However, he was not a rich son who could appreciate the hardships of soldiers. Every time he fought, there were several large carts of reserve supplies specially prepared for him, and often there were still supplies left after the battle. However, ordinary soldiers could be hungry and cold. On the contrary, Li Guang, the general of the same period, everyone knows his great battle achievements, and the Xiongnu were even more fearful of him. But what is more worth learning is Li Guang's love and consideration for his subordinates. It was this kind of superior who really integrated into the masses that gained the true support and trust. Although Li Guang was never able to be a marquis for various reasons, he was more like a great general in the hearts of many people. In contrast, Huo went on to become since he was able to have the courage and strategy to be blessed with heaven. Li Guang's benevolence, Li Guang's Strategies, Li Guang's courage, Li Guang's ability created this general who has been known for centuries. If we become a leader in the future, we must not only have the ability, but also know the art of getting along with subordinates. Cooperation, assistance, win-win, mutual understanding are what we have to learn. From a small person to a large country, "Zizhi Tongjian" provides us with a typical example to learn from, so let's read it sometime to understand the history of our country and learn from it the truth of being a person and even governing.
