The general trend of the world is that if it has been divided for a long time, it must be united, and if it has been united for a long time, it must be divided. The seven kingdoms fought over the weekend and merged with Qin. After the fall of Qin, Chu and Han fought separately and merged with Han. The Han Dynasty revolted after Emperor Gaozu killed the White Snake and unified the world. Later, it was revived by Guangwu and spread to Emperor Xian, and it was divided into three kingdoms. The cause of the chaos probably started with Emperors Huan and Ling. Emperor Huan imprisoned good people and respected eunuchs. When Emperor Huan died, Emperor Ling ascended the throne, and General Dou Wu and Grand Tutor Chen Fan assisted each other. At that time, the eunuch Cao Jie and others took power, and Dou Wu and Chen Fan plotted to kill him. However, the matter was not kept secret, and he was harmed instead. Zhongjuan became more and more tyrannical from then on...
When Jie and Zhou lost the world, they also lost their people; when they lost their people, they also lost their hearts. There is a way to win the world: if you win its people, you will win the world; if you win its people, you will have a way: if you win their hearts, you will win the people.
Mencius said that the people are the most valuable, the country is the second most important, and the king is the most important. Therefore, the people of Qiu became the emperor, the emperor became the princes, and the princes became the officials. If the princes threaten the country, they will change their positions. The sacrifice is completed, the rice is abundant and clean, and the sacrifice is timely. However, if there is a drought and water overflows, it will become a state of affairs!
