The history book Zuo Zhuan Xiang Gong Twenty-six Years records the suggestion of collusion adopted by Bozhou Plough, Taizai of the State of Chu in 547 BC.
When the State of Chu attacked the State of Zheng, Dr. Chu took Kangdi of the State of Zheng alive with a seal, and King Chu's younger brother tried to take Kangdi away as his own meritorious service. He argued with the seal, and it was difficult for everyone to make a decision. King Chu Kang asked Bozhou Plough to judge right and wrong. Bozhou Li said, "Prisoners of war are people with status in Zheng, so we know who will catch them." It is to let the emperor stand in the court and let his son stand opposite the emperor with a seal. Bozhou Li raised his hand and said, "This is Gongzi Wei, a widowed gentleman and your brother." Then let go and said, "This man wears a seal and is also a county magistrate outside Fangcheng (the Great Wall in northern Chu in the Spring and Autumn Period). Who captured you? " Seeing this, the emperor replied that he was captured by the childe. Soon, the emperor was released and returned to China.
When Bozhou Plough asked the emperor about the exploits of Chu, he deliberately indicated to the emperor the identities of the two exploits, and hinted to the emperor with different "collusion" gestures that he wanted to please the dignitaries before the seal. It seems that Huang Jie got the news of Bozhou plough through hints. As a prisoner of Chu, he longed to be released. In order to please the authorities in Chu, he listened to the hint of Bozhou Plough and was forgiven.
Hinting is a special "language" way adopted by the actor to convey some secret meaning to the other party when there is a third party. In the implementation of the proposal law, the existence of a third party is undoubtedly an obstacle to the exchange of ideas between the actor and the trustee. However, every successful suggestion method, the third party present actually played a cover role in conveying the actor's hidden feelings. For example, with Qin Kanggong present, the Qin people would not doubt that the scholars accepted some explanation of the defense and cooperated with it; With Dai Feng present, it is difficult for him to point out that Bozhou Plough deliberately misled the emperor. The actor hinted a secret feeling to the right person, and they didn't want anyone to know that they had an exchange of ideas. Because successful suggestion is always hidden from the third party present, the presence of the third party just covers up the exchange of ideas between them and plays a very good role in covering up their behavior.
Hint is to express a normal idea in an abnormal way, so its object should be a wise man to some extent. Formal hinting means may include staring at the foot, gesture induction, language prompt and so on. No matter what form it takes, it always conforms to the specific implied situation, so that the other party can understand it accurately and not let the third party see through it.
However, Bozhou Plough did not please him, although he courted him. Later, the son usurped the throne around his nephew and was called King Chu Ling. He didn't trust Bozhou plow and killed him. After King Ling was overthrown by King Chu Ping, his son Wan was reused.
