Loyal ministers strive to make the king noble in character, while sycophantic ministers strive to expand the king's territory. How to prove this? Xia Zhengshu of Chen State killed his king, King Zhuang of Chu sent troops to attack him, and the people of Chen State also obeyed the order of King Chu. After King Zhuang defeated the guilty people, he left his troops stationed in the state of Chen. All the officials of the state of Chu came to congratulate him. At that time, Uncle Shen was on a mission to Qi, but he did not express congratulations after returning home. King Zhuang of Chu asked Uncle Shen: "The rebellious ministers of Chen State were treasonous and immoral. I launched an army to attack them, quelled the rebellion and punished the guilty. All the ministers came to celebrate, but you are the only one not to celebrate. Why?" Uncle Shen said, "Someone is leading a cow. Trampling on someone else's field, the owner of the cow killed the owner and took away his cow. The person who led the cow was guilty, but such a punishment was too severe. Today, you think that the regicide of Chen Guo was a treasonous person. After sending troops to conquer, the guilty ministers were already killed, but they still sent troops to station in Chen State. When the princes heard about this, they thought that your king's purpose in sending troops to conquer was not to kill the guilty ministers, but to covet others' countries. I heard that a gentleman will not abandon morality to seek benefits." King Zhuang of Chu said, "You are right." So he withdrew the troops guarding Chen State and appointed the descendants of the king of Chen as the new king. After the princes knew about this, they all came to Chu to worship. This is trying to make the king noble. Zhang Wu gave Zhibo an idea and said: "Among the six generals of Jin, Zhongxing and Wenzi are the weakest, and they are also divided among themselves. Now is the time to attack them and expand our territory." Zhibo then followed Zhang Wu's advice. He planned to send troops to attack Bank of China and Wenzi clan. After wiping them out, Zhang Wu instigated Zhibo to ask for land from the Wei, Han, and Zhao families. The Han family and the Wei family ceded land to him, but the Zhao family refused to cede it. Zhibo then coerced the Han and Wei families to attack the Zhao family together and besieged Jinyang for three years. Later, the three families of Zhao, Wei, and Han secretly united, discussed in secret, and attacked Zhibo together, thus annihilating the Zhibo family. This is the result of striving to expand the king's territory. Try your best to make the king's moral character noble, and the king will eventually dominate the world; try your best to expand the king's territory, and the king will eventually be eliminated by others. Therefore, a small vassal state with thousands of chariots can rule the world as long as it implements virtuous governance, like King Tang of Shang and King Wu of Zhou; while a big country with thousands of chariots, if it likes to expand its territory, will eventually lead to destruction, like Zhibo. In the past, Zhi Bo was arrogant and attacked Zhongxing Wenzi and defeated them. He also coerced the monarchs of Han and Wei and cut off their lands. Still feeling unsatisfied, he raised an army to attack Zhao. The two kings of Han and Wei retaliated. Zhibo was defeated at Jinyang City and died in the east of Gaoliang City. His head was used as a drowning weapon. The country was divided into three parts and was laughed at by everyone in the world. It is the disaster caused by not being satisfied. Lao Tzu said: "If you know that you are satisfied, you will not be humiliated. If you know that it is enough, you will not be in danger. In this way, you can maintain it for a long time." This is what he meant.
