At the beginning, King Wen of Chu took advantage of the fact that Marquis Cai and Marquis Xi were attacking each other, destroyed the State of Chu, snatched Hou Xi's wife Concubine xi as his wife, attacked the state of Cai, and imprisoned Marquis Cai in the state of Chu until his death. Since then, the State of Cai has submitted to the State of Chu, and the sphere of influence of the State of Chu has reached the border of the State of Zheng.
After that, although the State of Chu fell into a situation of doubt due to the unexpected death of King Wen of Chu, its Ling Yin Ziyuan still launched an attack on the State of Zheng. However, it was also the internal instability of the Chu State, and the Chu State's attack on the Zheng State was fruitless. But this was enough to shock Zheng Guo.
Next, after King Cheng of Chu killed his brother and seized the throne, he sent several troops to attack the State of Zheng, hoping that the State of Zheng would submit to the State of Chu. However, at this time, it was the time when Qi Huan was dominating the princes of the Central Plains, and Zheng Guo, as one of the princely states of the Central Plains, did not dare to renege on the covenant of the Duke of Qi Huan. For the offensive of the State of Chu, Zheng Guo could only endure in silence except to report to Qi Abroad.
Duke Huan of Qi was also dissatisfied with the Repeated Attacks of the State of Chu on the State of Zheng, so he summoned the princes to prepare to discuss and teach the State of Chu a lesson. However, before the alliance began, the Duke of Luzhuang died, and the State of Lu fell into the Rebellion of Qing father. Duke Huan of Qi could only temporarily put aside Zheng Guo's affairs and concentrate on dealing with the chaos in the State of Lu.
Just at this time, the Di people invaded the state of Xing and the state of Wei, and the Duke of Qi Huan was immediately anxious, and he could not help the Chu state for the time being.
The State of Chu did not miss this opportunity, attacking zheng twice in succession, imprisoning a nobleman of the state of Zheng and annexing his fiefdom. Zheng Wengong was very afraid of this, and gradually had the intention of turning his back on Duke Huan of Qi and submitting to the State of Chu.
Although Duke Huan of Qi did not know Zheng Wengong's thoughts, he was really anxious about Zheng Guo's affairs, after all, if Zheng Guo submitted to the State of Chu, it would be a major blow to the hegemony of the State of Qi.
As a result, duke Huan of Qi immediately summoned the princes to deal with the State of Chu after settling the civil strife between the remnants of the xing and wei states and the state of Lu.
It was at this time that Cai Guo would send the concubines sent back to Cai Guo by the Duke of Qi Huan to marry someone else. Duke Huan of Qi took this as a name and led a large army of princes to attack the State of Cai. After teaching the Cai kingdom a lesson, the princes' armies approached the border of the Chu state, who expected that the king of Chu Cheng had already chen soldiers on the border and was waiting for him.
When King Wen of Chu saw that the princes' armies were coming, he sent emissaries to ask Duke Huan of Qi why he attacked the State of Chu. Guan Zhong, the chancellor of the Duke of Qi Huan, replied: "The State of Chu has not paid tribute to the Zhou royal family for a long time, and the State of Qi, as the prince Fang Bo appointed by the Zhou Royal Family, has the right to requisition the State of Chu for this purpose." He also said that he wanted to ask the cause of death after king Zhou Zhao's death after cutting down Chu.
This envoy of the State of Chu said that it was indeed the fault of the State of Chu that there was no tribute to the Zhou royal family, and that the State of Chu would resume the act of paying tribute to the Zhou royal family in the future. As for the cause of King Zhou Zhao's death, the emissary asked the princes to ask the people by the river. Because King Zhou Zhao, after the victory of Chu, fell and drowned while crossing the river.
Seeing that the Chu state was properly prepared, the princes did not rush to attack, but continued to march towards the Chu state and stationed themselves in The Land. When King Wen of Chu saw that the princes' army would not give up, he sent Qu Quan to lead his army to Jingdi to confront the princes' army.
Seeing that the Chu army was not weak, and if they really wanted to engage in battle, they might not be able to take advantage, so they withdrew to Zhaoling. Invite Qu Quan to the camp of the princes, hoping to intimidate him with the princes' army, in order to end with dignity. It is not expected that after bending down, he is not afraid of the military power of the princes and confronts the princes tit-for-tat. In the end, the two sides reached an agreement, signed a pact, and then withdrew their respective troops. This is the Alliance of Summoning Tombs.
The alliance of zhaoling made Zheng Wengong feel the power of the Chu state and the weakness of the princes even more. This made Zheng Wengong more inclined to the Chu state.
The following year, Duke Huan of Qi summoned princes to support the Zhou crown prince Zheng in succeeding to the throne. King Hui of Zhou was very dissatisfied with this, and he liked the prince belt and wanted him to inherit the throne. Therefore, King Hui of Zhou summoned Zheng Wengong and made him obey the State of Chu and unite with the State of Jin to undermine the appeal of Duke Huan of Qi.
Zheng Wengong originally wanted to submit to the State of Chu, but it was only because the prestige of Duke Huan of Qi was too great among the princes that he had to submit to the State of Qi. Now that he heard King Hui of Zhou say this, he would not go to the alliance meeting convened by The Duke of Qi Huan.
The following year, the State of Qi led a large army of princes to attack the State of Zheng and attack Zheng Guo's betrayal. At this time, Zheng Guo's new eldest brother Chu Guo attacked Xu Guo, forcing the princes to stop attacking Zheng Guo and rescue Xu Guo.
As soon as the princes' army arrived, the Chu state withdrew. At this time, the great army of princes not only lost their vigor, but also did not inherit the grain and grass, and they all withdrew and returned to China.
After the princes retreated, Xu Guo's ruler Xu Gong personally went to the Chu state and submitted to King Cheng of Chu.
Later, the State of Qi attacked the State of Zheng, causing the State of Zheng to submit to the State of Qi again. However, Zheng Guo only did this because of the situation, and the alliance of ZhaoLing had long allowed Zheng Guo to see the rise and fall of the hegemony of the Chu state and the prosperity and decline of the hegemony of the state of Qi.
