Although Zheng Guo was under the governance of Zheng Zhuang Gong. The national strength is very prosperous, and it occupies the first place in the competition for hegemony among the princes in the early Spring and Autumn Period, but as the so-called "prosperity must decline", so after the death of Zheng Zhuang Gong, several sons competed for the position of monarch. Fight to the death, and the doctors in it can not worsen the situation, Song, Wei and other countries were not really with Zheng Guo, seeing Zheng Guo in such a situation, they have made a big move against Zheng Guo, in the 22 years of turbulent situation, Zheng Guo finally established the hegemony evaporated like a flash in the pan.

To be honest, the reason why Zheng Guo's civil strife was already in the period of Zheng Zhuanggong, Zheng Zhuanggong accepted many wives and concubines, and Zheng Zhuanggong doted on his children very much, so the sons were all legal heirs. In the face of the reality of the collapse of etiquette in the Spring and Autumn Period, there were not many reliable guarantees, when Gongzi was ordered by Zheng Zhuang Gong to assist the Qi State in repelling Beirong. Duke Qi planned to marry his daughter to Gongzi Hu, but Gongzi Hu refused, and at that time the priest did not approve of this move, and he once persuaded Gongzi to agree to this family affair in order to gain the support of Qi in the future competition for the throne of the king. However, Childe did not follow his advice after all, and this decision did adversely affect him in the future.

After the death of Zheng Zhuang Gong, under the auspices of the priest Zhong, Gongzi Hu succeeded to the position of Zheng Guojun, known as Zheng Zhaogong in history. But the position has not been done too long, and Zheng Zhuanggong is the other one. Son Gongzi Tu, his mother is the daughter of the Yong family of the Song State, the Yong family, deeply favored by the Duke of Song Zhuang, has a lot of influence in the Song State, the Yong family originally expected Gongzi Tu to ascend the throne and be able to expand the sphere of influence of the dominant family, but Gongzi Hu's succession to the throne made their wishful thinking empty.

So they instigated the Song State to try to deceive the sacrifice Zhong and Gongzi Tu to the Song State and imprisoned them, while threatening the sacrifice Zhong with death, forming an alliance with the Song Dynasty and supporting Gongzi Tu to succeed Zheng Guojun, and at the same time asking Zheng Guo to pay a large amount of money, at this critical moment the sacrifice Zhong was greedy for life and afraid of death, not to alarm Yao, so he could only agree to the request of Song Zhuang Gong, under the escort of the Song army, the sacrifice Zhong brought Gongzi Tu back to Zheng Guo, and established Zheng Li Gong as the monarch. Zheng Guo's sacrifice was very weighty, and there was Song Guo as a backer, so naturally no one openly opposed this decision, and Zheng Zhaogong had no choice but to flee to Weiguo.

After Zheng Ligong succeeded to the throne, Song Guo Yan regarded himself as a benefactor, and frequently asked Zheng Guo for property, many times, Zheng Ligong naturally couldn't bear it, and the relationship between Zheng Guo and Song Guo gradually deteriorated, and at this time Lu Guo wanted to mediate. He made an alliance with Song Hui in the hill of sentence and persuaded Song Zhuang Gong to reconcile with Zheng Guo, but who knew that Song Guo resolutely refused.

After that, Lu Guo met with Song in Xudi and Guidi respectively, but Song Zhuanggong still refused to change his attitude. Lu Guo, who felt that he had lost face, was angry and formed an alliance with Zheng Guo in Wufu to jointly crusade against the Song State. In the second year, Zheng and Lu united with Ji and sent troops to attack Song, while Song united Qi, Wei and Southern Yan to resist.

As the so-called "hundred-legged insects, dead but not stiff", although Zheng Zhuanggong died and Zheng Guo had civil strife, Xiaoba Yu Wei still existed. The two armies fought, and the Zheng Luji coalition army actually won a complete victory. Since then, the alliance between Zheng and Lu has become closer, and the two sides have made two more alliances. However, it didn't take long for the Song State to make a comeback, gathering Qi State, Wei State, Chen State, and Cai State to attack Zheng together. The two fists were finally invincible to the four hands, and this time Zheng Guo was outnumbered and suffered heavy losses. The alliance of the five countries invaded Xinzheng, burned the city gate, and looted when the troops retreated, and even the timber of the ancestral temple of Zheng Guo was demolished back to build the city gate of the Song State. After this battle, Zheng Guo not only lost the land of the cow's head, but more importantly, the country's image was greatly humiliated, even the ancestral temple of the ancestors was demolished by other countries, what a shame that era was, and the era of Zheng Guo as the overlord is gone.

However, Jeong's bad luck is far from over. Before recovering from the fiasco, Zheng Guo had another civil strife. The doctor is a veteran of the two dynasties, with huge power and meritorious support, so he is inevitably autocratic. This made Zheng Ligong very dissatisfied, so he came up with the idea of getting rid of the priest.

In the twenty-third year of King Huan of Zhou (697 BC), Zheng Ligong wooed Yongjiao, the son-in-law of Sai Zhong, and the two secretly discussed, intending to invite Sai Zhong into the palace in the name of a banquet and kill him at the banquet. The plan has been decided, but unexpectedly, Yongjie is not secret, and tells his wife Yongji about it. When Yongji learned about this, she was in a dilemma, so she asked her mother, "Which is more important, father or husband?" In ancient times, filial piety was the greatest, so my mother replied, "There are many men, but there is only one father." You tell me? Yongji told Zheng Ligong's plan to the priest Zhong. The priest then killed Yongjie and threw him out of the city. Zheng Ligong saw that nothing could be done, so he had to flee to Cai Guo. The priest welcomed Zheng Zhaogong back to Zheng Guo to restore the throne.

However, Zheng Zhaogong's ascension to the throne this time was still not long. When Zheng Zhaogong was still a son, he didn't like the doctor Gao Qumi, and he had repeatedly suggested that Zheng Zhuanggong be estranged from him. Although Zheng Zhuanggong did not listen to Gongzi Hu's opinion, Gao Qumi developed hatred for Gongzi Hu because of this. After Zheng Zhaogong was reinstated, Gao Qumi was worried that he might attack him, so he attacked first, pretending to invite Zheng Zhaogong to go hunting, and killed the latter on the way.

Gao Qu Mi and Sai Zhong, who succeeded in killing the monarch, helped Zheng Zhuanggong's other son, Gongzi, to the throne of the monarch. In the second year, Qi Xianggong met at the first end of the defense of the country and invited Zheng Guo to participate. Because Gongzi had a fight with Qi Xianggong, who was also a prince at the time, during the alliance when he was young, and they were not on good terms with each other, the priest suggested that Gongzi refuse it. However, Gongzi decided to go because he thought that this alliance could avoid giving the princes support to Zheng Ligong, who was still in exile. The priest who failed to dissuade himself said that he was ill, and Gao Qumi accompanied him as a courtesy. As a result, the facts once again proved the foresight of the priest: Qi Xianggong asked Gongzi to apologize for the past when he met the alliance, but the latter refused, and Qi Xianggong, who was furious, set up an ambush and killed Gongzi Shu, and Gao Qumi was also split by the car.

After the death of Gongzi, Sai Zhong had no choice but to welcome back Zheng Guoguo as the monarch of the country. However, at this time, Zheng Ligong gradually gained the support of the princes and gradually became stronger. It didn't take long for Zheng Ligong, who had fled to Cai, to return to Zheng and occupy Liyi, and gain the support of Lu. The state of Lu has met with the princes twice, and organized a coalition army to attack Zheng several times, in an attempt to support the restoration of Zheng Ligong. Although it was always fruitless, Zheng Guo was trapped in continuous civil strife and was no longer Zheng Ligong's opponent.

In the second year of King Xi of Zhou (680 BC), Zheng Ligong attacked Zheng Guo, fought with Gongziyi in Daling, and captured the doctor Fu Fang. In order to save his life, Fu Fang was coerced and lured by Zheng Ligong and expressed his willingness to return to Zheng Guo as an internal officer. Sure enough, after returning to China, he took advantage of Gongzi's unpreparedness and killed the latter and his two sons. Zheng Guo was in turmoil again, and Zheng Ligong took the opportunity to return to China and re-ascended to the throne of the monarch.

This is the end of Zheng Guo's turbulent situation. After decades of internal strife and external troubles, as well as the rise of the Qi State, Zheng Guo at this time has almost lost the status of "Xiaoba". However, Zheng Ligong is still a promising king, and under his leadership, Zheng Guo will also leave the last glory on the political stage in the early Spring and Autumn period.

Although the situation of Zheng Guo's small hegemony is over, the Zhou royal family, which has been suppressed by Zheng Guo for a long time, has not been given a chance to breathe. On the contrary, with the collapse of the patriarchal system, the contradictions within the Zhou royal family were also extremely acute, and the "Prince Decadence Rebellion" that broke out in the early years of King Hui of Zhou made the status of Zhou Tianzi fall into an unprecedented trough again.

Wang Zi is the concubine of King Zhuang of Zhou, and he is deeply favored by King Zhuang. However, since the ancient dynasty has always practiced the primogeniture system, he has no inheritance right. After the death of King Zhuang, he was succeeded by his eldest son, Prince Hu Qi, who was the king of Zhou. Who knew that within a few years, King Zhou Xi also died. His son Lang succeeded to the throne as King Hui of Zhou. And Wang Ziqi became Zhou Tianzi's uncle. Although you are an uncle of the king, he has lost the position of the son of heaven that may have belonged to him, and watching his nephew, who is about the same age as himself, become the co-ruler of the world, the prince is obviously angry about this.

After King Zhou Hui ascended the throne, he was not only unaware of the prince's dissatisfaction, but was busy begging for land and buying palace properties for himself. As soon as King Fu of Zhou Hui ascended the throne, he relied on the power of the Son of Heaven to forcibly seize the garden of the country of Dafu and take it for himself, and then requisitioned the residence of the doctor Bian Bo and changed it into a palace.

King Zhou Hui's actions inevitably caused dissatisfaction and complaints among the courtiers. What's worse is that the country is no one else, but the teacher. So under the contact of Jiang Guo, these doctors got together and discussed supporting the prince as the son of heaven. And this plan was secretly supported by the doctor Su. During the reign of King Huan of Zhou, he once exchanged the twelve cities of the Su clan with Zheng Guo for fields. This practice not only angered Zheng Zhuanggong, but also made Su quite angry. So he conspired with the five doctors to rebel.

In the second year of King Hui of Zhou (675 B.C.), Jiang Guo, Bian Bo, Zi Yu Zhu Knee, Zhan Father, and Shan Fu jointly raised troops to attack King Zhou Hui, but unexpectedly the division was unfavorable, and the five doctors were defeated by King Zhou Hui, so they had to flee to Su's fiefdom Wen, while Jiang Guo served the prince and fled to Weiguo. The prince said that he moved Wei Guo to support him, so Wei Guo united with Nanyan State to raise troops and attack the Zhou royal family. This time, King Zhou Hui suffered a defeat and had to run. The prince then returned to Chengzhou and was proclaimed the Son of Heaven by the five doctors.

The civil strife in the Zhou royal family gave Zheng Ligong, who had just been reinstated, a chance to regain his prestige and status. After Zheng Ligong was reinstated, in order to end the turmoil caused by the long-term civil strife, he spent a lot of effort to re-establish his authority. He first killed Fu Fang, who had supported him, on the charge of killing the king, and then forced the old minister Yuan Fan to death on the grounds of not supporting himself. Subsequently, he executed and punished Gongzi Yan, Qiang Jun and others, and eliminated the influence of the dead priest Zhong in Zheng State. After the domestic stability was stabilized, Zheng Ligong set his sights on King Zhou Hui, who was trapped by the prince's rebellion.

In the third year of King Hui of Zhou (674 BC), Duke Zheng Li said that he wanted to mediate the civil strife of the Zhou royal family, hoping to restore King Hui of Zhou at the cost of pardoning the crimes of the prince. But the powerful prince refused the offer. Seeing that the matter could not be done, Zheng Ligong sent troops to attack the Zhou royal family and captured the king of the Southern Yan Kingdom, Zhongfu. Later, he welcomed the exiled King Zhou Hui to his former base of Liyi and settled down. Later, he crusaded against the prince again, broke the Zhou army, and snatched back the tools that had been passed down from generation to generation of the Zhou royal family and could only be used by the Son of Heaven and presented them to King Zhou Hui.

Although the usurper prince is not Zheng Ligong's opponent, if you want to completely eradicate the prince and support the restoration of King Zhou Hui, it is far from enough to rely on Zheng Guo's power alone. Both Wang Zi and Zheng Ligong knew this deeply. This winter, he felt that Zheng Guo had nothing to do, and the prince who sat firmly on his throne had a big banquet to reward the five doctors who supported him. The scene was extremely luxurious and grand, and the "Zuo Biography" recorded that the scene at that time was "happy and danced", that is, the ritual music of the Yellow Emperor, Yao, Shun, Xia, Shang, and the Six Dynasties was used to help the banquet.

In the Zhou ceremony, the ritual music of the six generations can only be enjoyed by the Son of Heaven, and it is an extremely solemn and serious matter, and the informal sacrificial ceremony cannot be taken lightly. And the prince, as the usurper of the throne, enjoyed it with the doctor, which is undoubtedly a serious act of rebellion. Zheng Ligong seized this opportunity and sent an invitation to the Kingdom of Yu to jointly crusade against the prince. He personally met with the monarch of the kingdom of Qiu, saying that the prince's tireless singing and dancing was a sign of trouble, and it was better to take this opportunity to support the restoration of King Hui of Zhou. Yu Guo and Zheng Guo were originally the secretaries of the Zhou royal family and had a very close relationship with the Zhou royal family, so they did not hesitate to agree to Zheng Guo's request.

In the spring of the following year, Zheng Guo and Yu Guo met in Yidi, and then besieged Cheng Zhou in two ways. Duke Yu entered through the north gate, and Duke Zheng Li escorted King Zhou Hui through the south gate. In the face of superior forces, the prince and his party were attacked by the enemy, and they were powerless to resist, and they could not escape for their lives in the defeated army, and all of them died. This was the end of the three-year-long "Princely Rebellion".

King Hui of Zhou, who re-ascended the throne of the Son of Heaven, was naturally grateful to Zheng Guo and Yu Guo. In order to reward Zheng Guo, King Zhou Hui also invited Zheng Ligong and the monarch of Yu Guo with six generations of ceremonies, and gave them a large amount of treasures, and even gave Zheng Guo all the land east of the Tiger Prison. However, as the so-called happiness begets sorrow, when King Zhou Hui rewarded the two, he gave the queen the sword used by the queen, that is, the mirror, to Zheng Ligong, and gave the lord he used, that is, the wine glass, to the king of the kingdom of Yu. Jue is a more valuable thing than Jian, Zheng Ligong thinks that his hard work is high, but the utensils he received are not as good as the kingdom of Yu, so he complained to King Zhou Hui. The relationship between Zhou and Zheng, which has just improved, is about to deteriorate again.

The life of the Zhou royal family did not improve because of the end of the prince's decadent rebellion, and the Zhou royal family, which had been hit politically, lost a large area of land because of King Zhou Hui's swollen face and fat man's behavior, and since then its power has been declining, and it can only continue to be played by powerful princes. However, Zheng Ligong did not have time to retaliate against the Zhou royal family. Not long after King Hui of Zhou was reinstated, Zheng Ligong died, and the last glory of Zheng Guo completely disappeared with the death of Zheng Ligong. Since then, Zheng has gradually become a second-rate vassal state. On the stage of the Spring and Autumn Period after Zheng Guo, a vassal state from the East rose rapidly, and the Spring and Autumn Period entered the era of the five hegemons.
