I read the Left Transmission seventy (653 BC) for the seventh year of Lu Qigong

Zheng Guo became the protagonist of this year, but he showed a weak and incompetent side of the wall.

First, it had been allied with the State of Chu for less than a year, and had rebelled against Chu and returned to Qi. In the spring, the State of Qi attacked the State of Zheng, and Zheng Guo sent a representative of the State of Qi, Uncle Kong, to suggest surrendering to the State of Qi, saying: "As long as you are not high-minded and far-reaching, there is no excessive worry, if you want to be strong, you cannot be strong, and you are not willing to be weak, so there is constant trouble, we only have to lower our stature, put ourselves in the right position, and concentrate on relying on the State of Qi!" Zheng Wengong was still thinking about waiting to see if Chu Guo could come to save himself, and Uncle Kong said, "It's too late, I can't wait any longer." So Zheng Wengong decided to rebel and return to Qi.

Second, Shen Hou, the second villain of the Spring and Autumn Period, was killed. In 656 BC, after the Battle of Zhaoling, Marquis Shenhou of zhengguo stabbed Chen Guofu with two sides and three swords, offered tribute to the Duke of Qi Huan, and was given the title of Caiyi (蔡邑), resulting in the princes cutting down Chen and the capture of Yuantao. After Yuan Tao was released, he was angry in his heart, but he did not show it, but acted as if he were no one else, and still interacted with Shen Hou. Once, YuanTao said to Shen Hou: "The terrain of Tiger Prison Pass is precarious, if you can further strengthen the city pool and then do some greening and lighting, it will certainly be famous, the merit is in the contemporary era, and the benefits are in the thousands of autumns." Shen Hou was happy to listen. YuanTao turned his face and said to Zheng Wengong, "Shen Hou reinforces the Tiger Prison Guancheng Pool, this is to rebel!" Zheng Wengong was forced to give the Tiger Prison to Shen Hou, and he hated Shen Hou even more. In the same year, in Xia, Zheng Wengong killed Shen Hou to please Yu Qi, because Qi Huan Also knew that he had been deceived by Shen Hou.

Third, Prince Hua committed treason against the country. Prince Hua of Zheng was sent by Zheng Wengong to attend the alliance of princes, and the princes discussed whether to accept Zheng Guo's surrender and let Zheng Guo rejoin the alliance led by Qi. Guan Zhong's opinion was to treat all the princely states according to morality and etiquette, then everyone would consciously unite around the state of Qi. Prince Zheng privately approached Duke Huan of Qi and said, "The main people who oppose the State of Qi in our country are the three families of the Huan, Kong, and Zi clans, and if you help get rid of these three families and let me become the monarch of the State of Zheng, I am willing to become a vassal state of the State of Qi." Qi Huangong was very attractive when he heard it, and was ready to promise him. Guan Zhong said: "We meet the princes with a letter of courtesy, and Zihua violates his father's orders for personal gain, and is rude and untrustworthy. Qi Huangong said: "We dispatched so many troops, but we did not achieve complete victory, and now there are contradictions within Zheng Guo, so we will take advantage of the opportunity to take it, can't we?" Guan Zhong said: "Use virtue to appease, use justice to teach, if he does not listen, he will command the princes to fight, then Zheng Guo will soon be destroyed and cannot take care of other things, and he will be afraid and surrender." If you condone a traitor like Prince Hua, then Zheng Guo will be justified, and he will not be afraid; the organization of the alliance of princes is based on the premise of morality, and now using the traitors to opportunistically, what will future generations think? The joint actions of many countries, moral, criminal, ceremonial, righteous and other acts will be recorded in the history books of various countries, and if the traitor is supported as the monarch, then the status of our country's ally will not be guaranteed. If you do something bad that cannot be recorded in the history books, you are not moral! If you don't listen to Prince Hua's bad idea, Zheng Guo will immediately submit to us. In the winter, Zheng Guo went to the State of Qi to ask to join.
