Chinese civilization has been vast for five thousand years. How many heroes have been silent in history, and how many proud men have criticized Fang Qiu in the history books. From the founding of the Han civilization by Liu Bang, the founder of the Han Dynasty, to the Han culture that can be seen everywhere in today's history, as Yang Shen said, the rolling Yangtze River passes eastward, and the waves wash away the heroes. Right and wrong, success and failure are all gone, but the green mountains are still there. The sunset is red several times, and the white-haired fishermen and woodcutters on the river are used to watching the spring breeze, a pot of turbid wine, and happy encounters. Many things in ancient and modern times are all talked about and laughed at. It is wise to read history, not to chew it carefully, but to hope that readers can gain something from it.
