Zheng Ligong's forbearance and strategy

Zheng Guo's military victory did not last long, and in 701 BC (the eleventh year of Lu Zhigong), Zheng Zhuanggong died, and four of the eight sons he left behind participated in the struggle for the throne. Until 680 BC (the fourteenth year of the Duke of Luzhuang). Three of the four people who participated in the struggle for the throne were killed, and until Zheng Ligong re-entered the country, for 22 years, civil strife had been plagued by Zheng Guo, leaving it with no time to take care of the outside world, and the favorable situation created by Zheng Zhuanggong was naturally lost.

At this time, the minister who manipulated zheng guo's power was Ji Zhong. After the death of Zheng Zhuanggong, it was he who made the crown prince Zheng Zhaogong. Another son of Duke Zhuang, Gongzi Tu, was born to the Song dynasty daughter Yong Shi. The Yong clan was very powerful in the Song Kingdom and was deeply favored by the Duke of Song Zhuang, and they lured Gong Zhong to the Song Kingdom and forced him to set up Gongzi Tu, and Gong Zhong had to agree to make Gongzi Tu the Prince of Jin, for Zheng Li Gong. Matsuri returned to China with Li Gong, and Zhaogong fled to Weiguo for refuge.

One of the purposes of the Song people in establishing Li Gong was to get more money and property rewards, after the Li Gong, the Song people continued to seek, Zheng Guo could not stand it, in 699 BC (the thirteenth year of Lu Huan Gong) united with Lu and Ji to fight a battle with Song, Qi, Wei, and Yan (Southern Yan) and won a great victory. The following winter. The State of Song also united with Qi, Wei, Chen, and Cai to take revenge. The Song forces burned the gates of Zhengdu city and attacked the city, and the Song people removed the beams on the roof of the Zhengguo Ancestral Temple and transported them back. The coalition forces also cut down the eastern outskirts of Zheng and captured Niushou (牛首; northeast of present-day Xutong County, Henan). The Zheng people suffered heavy losses in this war.

The losses of external military defeat have not yet recovered, and internal contradictions have arisen again. Because of his support for li gong, he practiced dictatorship in the country and did not pay attention to the monarch. Li Gong was a relatively capable figure and could not tolerate such arbitrariness. In 697 BC (the fifteenth year of the Duke of Lu Huan), he wanted Touhou's son-in-law Yong Gui to take advantage of the banquet to kill Himzhong. This matter was known to Yong Jiao's wife, Yong Jiao, whose father and husband were her relatives, and did not know how to deal with this matter, so she went to ask her mother; "Which of the father and husband is closer?" replied Yong Jiao's mother; "Any man can be your husband, but there is only one father, how can it be compared?" After Yong Jiao heard this, he told The Priest about Yong Jiao's conspiracy with Li Gong. Matsuri immediately killed Yong And threw the body in a pool outside the city. Zheng Ligong saw that the incident had been leaked, so he fled to Cai Guo with Yong Gui's body. Soon after, he infiltrated Liyi (栎邑, in present-day Yu County, Henan) on the southern outskirts of the State of Zheng, and instigated the Yi people to rise up and kill the shouyi governor Tan Bo. After Li Gong fled, Duke Zhao took the opportunity to return to China to restore the throne, and Li Gong was opposed to the Zhao Gong regime according to Shou Li Yi.

When Zheng Zhaogong was crown prince, he did not like the chancellor Gao Qumi, and after The Restoration of The Duke of Zhao, Gao Qumi was afraid of being killed, so he took the initiative and killed the Duke of Zhao in 695 BC (the seventeenth year of the Duke of Lu Huan) and established the brother of the Duke of Zhao. Qi Xianggong, who wanted to be the overlord, intervened, and in the autumn of the following year, he met with the first base of the Wei state (present-day southeast of Sui County, Henan) and booby-trapped and killed his son Gao Qumi. Ji Zhong, knowing that Duke Xiang of Qi might be in trouble and said that he was sick, soon took back Ziyi (also known as Zi Bao, Baby Ci) in the Chen Kingdom and established him as the monarch.

In the 14th year of Ziyi's reign (693 BC –680 BC), in the last year, Zheng Ligong organized a force to march to the capital at Liyi and captured Ziyi's doctor Fu Feng in the land of Daling, who told Li Gong; "If you let me go, I will help you return to china to become the monarch of the country," Li Gong let him go. Sure enough, when he returned, he killed Ziyi and his two sons and welcomed Li Gong back to China. After Li Gong returned to China, the first thing he did was to kill Fu Feng, a capricious villain. This is also his popular move.

In 680 BC (the fourteenth year of duke Luzhuang), when Zheng Ligong, who had been in exile for 18 years, was restored to the throne, it had been six years since Duke Huan of Qi came to power, and the situation had changed greatly, which was unfavorable to Zheng Guo. However, Li Gong still seized the banner of "King Qin", putting Zheng Guo in a favorable position for a time. In 675 BC (the nineteenth year of the Duke of Luzhuang), the Zhou royal family had a rebellion of princes. Prince Huan rebelled with the support of Huan Guo, Bian Bo, Zhan Father, Zi Fowl, Zhu Kneel (known as the Five Great Masters), and Su Shi. Because the Zhou royal family took in Duke Huigong Wei's political enemy, Prince Qianmu, Wei Guo also joined forces with Southern Yan to aid Prince Hui, expelled King Hui of Zhou from the capital, and established Prince Hui as king.

The following year, Zheng Ligong intervened to mediate the royal rebellion, so he captured the emperor of the Southern Yan state, Zhongfu, and placed King Hui of Zhou in Zheng's Liyi, and later entered Chengzhou. The following year, while Prince Hui and his gang were drinking celebratory wine, Zheng Ligong and Duke Yu jointly attacked Wang Du, killing Prince Hui and his gang and sending King Hui of Zhou back to Wangcheng. In order to thank Li Gong, King Hui gave the royal land east of Tiger Prison to Zheng Guo.

Among the several successors of Duke Zhengzhuang. Li Gong has the most to do. In 714 BC (the ninth year of the Duke of LuYin), Beirong went south to attack Zheng, Zheng used vehicles to fight, and Beirong used infantry, and Zheng Zhuanggong was worried that chariots were not as flexible as infantry and were not easy to deal with. At that time, Li Gong, who was still a prince (sudden), based on the weakness of the Rong people in fighting a war, "did not give in to victory, and did not save each other from defeat", proposed to ambush in three sections, using light pawns to lure the Rong soldiers to make them win small victories and compete for the spoils of war, and the Zheng army then made an ambush attack strategy, and defeated The Northern Rong. This shows that Li Gong has a great military mind and creative spirit. In the Oak Days, Li Gong was supported by the People of The Yi and finally returned to the country and was restored. Kill Fu Flaw and win the trust of the people. In the five or six years of the restoration, the royal rebellion was quelled and the Hui King was stabilized, and his merits to the royal family were not inferior to Qi Huan and Jin Wen. Just when he could use the merits of "Qin Wang" to compete for the throne of the princes, he died in May in 673 BC (the twenty-first year of the Duke of Luzhuang), otherwise the hegemony of the Duke of Qi Huan would not have been so smooth, and the banner of "Zun Wang" might have been waved by Zheng Ligong for a period of time. Zheng Ligong's mistake was that he wanted to get rid of the powerful ministers and improperly employed people, and eventually he was forced to live outside for a long time and spent years.
