Yan Zi set up a bureau: let Qi Jinggong invite three warriors to reward the three of them with two precious peaches; and the three people could not divide the two peaches equally, yan Zi proposed a coordinated method - three people compared to merit, and the greater merit could take a peach. Gongsun Jie and Tian Kaijiang both reported their own exploits first, and each took a peach. At this time, Gu Yezi thought that his merit was greater, and he was angry enough to draw his sword and accuse the former two; and After Gongsun and Tian Kaijiang heard Gu Yezi report their merits, they also felt that they were not as good as they were, and after being ashamed, they gave up the peach and committed suicide. Despite this, Gu Yezi was ashamed of the ugliness of humiliating others and making others sacrifice themselves, so he also drew his sword and killed himself--in this way, relying only on two peaches, he removed three threats without bloodshed.
In 354 BC, the Wei army besieged the capital of the Zhao state, Handan, and the Zhao state asked the state of Qi for help. The King of Qi then sent Tian Ji as a general and Sun Zhen as a military division, leading 80,000 troops to save Zhao. Tian Ji planned to go directly to the battlefield of Handan, while Sun Zhi suggested that he lead an army directly to the capital of the Wei state of Daliang, forcing the Wei army to return to the division to save itself, and the siege of Handan was lifted. The Qi army set up an ambush in the Guiling area of the Wei army's inevitable route, in order to wait for labor, and eventually defeated the Wei army. The beauty of this is that even if Wei Guo and Pang Juan saw Sun Zhen's purpose, they had to "plan", because they did not dare to gamble, and once the beam was lost, no matter how big the victory they fought, it would not help.
During the period of Emperor Wu of the Han Dynasty, the power of the princes was not only extremely large in land area, but also strong in strength, and often did not obey the dispatch of the imperial court. Therefore, the main father Yan thought of a plan for Emperor Wu of Han, that is, to order the princes not only to pass on the eldest son, but also to divide the titles for those second sons and concubines, and to have fiefs for all sons, which was called "Tui En Ling". The beauty of the Tuien Order is that once the Tuien Order is issued, the princes will not carry it out, the princely states will be divided or civil strife, the kingdom will be divided after the death of the old king, and if the Tuien Order is not implemented, the eldest son of the concubine is happy but not long-lasting, because after the death of the old king, the other sons will fight among themselves and kill each other, and if the last line will be extinguished, the kingdom will be taken back by the imperial court, and if you want the descendants to be stable, the only way to implement the Tuien Order is to be safe! Let you divide one side, the imperial court a paper "push grace order", your power "big become smaller, small change nothing" your young sons still have to thank me, willingly help me implement the policy, it is really wonderful!
"Holding the Heavenly Son to Order the Princes" was actually a suggestion given to Yuan Shao by Frustrated, and Mao Jiu's advice to Cao Cao was "to serve the Son of Heaven to order not to be subordinate, and to cultivate and plant with livestock and military resources", in addition, the earliest Jia Xu also proposed to Li Dai to "serve the country to conquer the world". Through the "signboard" of Tianzi, Cao Cao not only won Dong Zhao, Zhong Xuan and other former Han courtiers, but also won the hearts of a large number of scholars, Xun You from Jingzhou and Guo Jia from Yuan Shao to Cao Cao's command, to avoid the chaos of Jiangnan Du raid, Zhao Yu also returned to Xuchang the following year. Moreover, the great princes such as Yuan Shao, Ma Teng, Han Sui, Sun Ce, lü Bu and other great princes also had to choose to follow the edicts, for example, although Lü Bu actually owned Xuzhou, he had to send someone to ask Cao Cao, hoping that the imperial court would officially appoint himself as Xuzhou Mu. Although Liu Biao, the mu of Jingzhou, defended himself from his stronghold, he still had to submit to the Han court controlled by Cao Cao, and his contributions were endless. Cao Cao successfully mastered the "great righteousness of the world" through "feng tianzi to order not to be subordinate", and in the face of the edict issued from Xuchang, even if the princes knew that this was Cao Cao's intention, they could only choose to accept it helplessly. Because once you choose not to obey the commandment, then you become a real "Han thief", not only will be beaten by the group, but also lose people's hearts, which is the power of the "Tianzi signboard".
