In June of the fifth year of King Jian of Zhou (581 BC), Jin Jinggong, the overlord of the princes and the monarch of the Jin State, died (the specific death process will be introduced in detail later), and the prince of Jin Zhou Pu succeeded to the throne, that is, the twenty-seventh Marquis of Jin - Jin Ligong; The historical process of the Jin Kingdom has entered a new chapter.

During the reign of Jin Jinggong, he reused and trusted the doctor Bozong who gave him advice and repeatedly offered wonderful plans; And Bozong, who was reused by the monarch, also contributed all his talents and wisdom without reservation, and advised the Jin State and the Jin Jinggong to be loyal and solve problems.

Now, Jin Jinggong, who admired Bozong, died suddenly, and the prince of Jin, Zhou Pu, under the support of the chief ruling secretary - Luan Shu, the general of the Chinese army and the ruling doctor, and the second secretary, and the Zhongjun Zuo Xun Geng (Zhongxing Geng), successfully inherited the position of the monarch of the Jin State, and the Jin State had a new monarch.

The new monarch Jin Ligong and Bozong did not have much personal friendship, that is, an ordinary relationship between monarchs and ministers; Therefore, after the succession of Duke Li of Jin, the position of the old minister Bozong in the court of the Jin State was inevitably impacted and neglected; But at this time, the focus of Jin Ligong and other extravagant families is still on the external strong enemies - Qin State and Chu State, for a half-outdated old minister (Bozong), to be honest, Jin Ligong and Luqing really don't care much and attach much importance to it.

Under normal circumstances, Bozong in this environment should know each other and take the initiative to tell the old man (or rein in his edge and be a low-key person); However, Bozong's past career was too smooth and smooth, and the 'self-satisfied and proud' spirit in his heart still failed to turn the corner in time; after the succession of Jin Ligong, Bozong couldn't control his 'sharp teeth' mouth, and still relied on his proud 'vision and knowledge' in the court of things and people, and constantly expressed his views on many internal and foreign affairs, foreign affairs, and military affairs of the Jin State, and did not know the rank of the monarch and ministers, and gave many admonitions to the new monarch Jin Ligong, asking him to pay attention to some ' The high-ranking and powerful 'extravagant family (that is, in the Dark Yin family).

Such a low-key, restrained approach and attitude made Jin Ligong hate Bozong more and more; In the end, Bozong finally fell into bad luck and lost his life, and his family disappeared from the court of the Jin Kingdom (fortunately, his son went into exile and continued to work in another place, which caused great trouble to the Jin Kingdom).

The direct reason for Bozong's unfortunate death was that Zheng Guo, the current ally of the Jin State, brazenly sent troops to attack Xu without the consent of the alliance leader, which caused the intervention of the southern overlord Chu State, and the king of Chu sent troops to attack Zheng; Later, when the monarchs and ministers of the Jin court discussed and debated whether to send troops to aid Zheng immediately, Bozong, who attended the meeting, sprouted and said some inappropriate words, which caused the anger of the Duke of Jin Li and other ministers.

In addition, during the time before and after, Bozong also consciously or unintentionally repeatedly advised the Duke of Jin Li to be careful of the clans (that is, the Yin clan) who held great power, but the Duke of Jin Li, who was dissatisfied with Bozong, deliberately told the Yin clan these words in private; Angry and angry, 'Sanhe' came forward to frame Bozong for being suspected of 'Tongchu', plus despising the monarch, slandering the government, and slandering important ministers.

In the end, Bozong was arrested and imprisoned by Jin Ligong and 'Sanhe', and humiliated; Bozong was unwilling to be humiliated, and driven by his super self-esteem, he committed suicide in prison, and the Bo clan of the Jin State withdrew from the political arena of the mother country (Jin State) (of course, the descendants of Bozong were able to go into exile and survive, and later turned the clouds and rain in other countries and showed their talents, which is a later story).

Bozong's follow-up story will be put aside for the time being, and here is an introduction to the reasons for the 'Zheng and Xu two countries' that led to his final killing. In fact———— at the beginning, under the mediation of Hua Yuan, the Zhengqing of the Song State, the Jin and Chu countries reached the (first) 'Soldiers' Meeting in Shangqiu, the Song capital, in May of the seventh year of King Jian of Zhou (579 BC), and both sides sent representatives to participate in this oath, declaring a formal truce between the two countries and jointly maintaining friendly relations between the princes.

Therefore, the Duke of Jin attached great importance to the matter of the "truce covenant" of Jin and Chu, and after the two countries reached an oath, he also specially summoned the kings of Lu, Zheng, Wei and other allies to meet in Zoze (Daming County, Handan, Hebei), and personally read to them the alliance of Jin and Chu's "meeting of soldiers", and specially warned them to abide by this covenant; and the other side of the state of Chu will also ' The results of the 'Soldiers' were relayed to their allies, namely the vassal states of Cai, Xu, and Chen, and they were also required to abide by the 'Covenant of Soldiers'.

However, for their own interests, the two overlords of Jin and Chu could temporarily choose a truce to restore their national strength, in order to compete for hegemony in the future, but their allies (junior brothers) did not fully follow this covenant; Less than two years after the end of the (first) 'meeting between Jin and Chu's soldiers', Zheng Guo, an ally of the Jin State, used the incident of the 'Gongzi Ban Rebellion' that happened that year as an excuse to send troops twice in August of the eighth year of King Jian of Zhou (578 BC) to attack the Chu State's ally Xu Guo, once again provoking a war between the two camps.

And the matter of Zheng Guo's war against Xu was caused by an old grudge between the two countries in that year - in June of the 21st year of King Zhou Ding (586 BC), because of mutual resentment and mutual vigilance, there was a 'Zheng and Xu dispute', and Xu Linggong, the monarch of Xu Guo, ran to the Yingdu of Chu and reported Zheng Guojun Zheng Mourning Gong to the alliance leader Chu Gongwang; The 'black case' not only made Zheng Mourning Gong reprimanded and humiliated by the King of Chu, but even Zheng Dafu Huangxu and Sima Ziguo (that is, Gongzifa, one of the Seven Mu of Zheng Guo, and Zheng Mourning Gong's uncle) who went to Chu with him to distinguish and explain, were detained by Chu in Yingdu, and Zheng Guo's face was lost. Therefore, Zheng Mourning Gongcai, who was slapped in the face by Xu State, changed from belonging to the Chu State to the Jin State in a fit of anger.

According to the records of other historical books, the then prince of Zheng Guo and the current monarch of Zheng Guo (referring to the reign of Zheng Guojun in the eighth year of King Jian of Zhou) - Zheng Chenggong, the younger brother of Zheng Miangong, was appointed by his brother Zheng Miangong to accuse Zheng Guo when Xu Linggong went to Chu State to accuse Zheng Guo, and was appointed by his brother Zheng Miangong to go to Chu State as a "debate" envoy to defend and dispute with the king of Chu Gong. imprisoned Zheng Guogong's younger brother 'Xuan'.

Later, after the unremitting efforts of Zheng Guojun and his ministers, and a large number of gold silk offerings, Gongzi was released from Chu State; Although he was under house arrest by the Chu people, the Chu state was powerful, and there might be an alliance in the future, so Gongzi did not dare and could not hate the Chu people; But the Xu Linggong who made a small report and sued the black case, Gongzi remembered it firmly, and if there was a chance in the future, Gongzi would definitely take revenge and revenge on Xu Guo.

But the initial reason for the bad relations between Zheng and Xu was actually a long, long time ago - at the beginning, during the reign of Zheng Zhuanggong, the 'Spring and Autumn Xiaoba', because he coveted the fields and people of the neighboring country - Xu Guo, Zheng Zhuanggong deliberately found an excuse, and united Lu Yin Gong and Qi Duke to attack Xu Guo on the grounds that Xu Guo did not listen to the orders of the Son of Heaven.

Xu Guo's strength was weak and he could not defeat the Three Kingdoms Alliance, so he was defeated without surprise; After the defeat, Xu Zhuanggong, the monarch of Xu Guoguo, had to abandon the country and flee to Weiguo to hide, and later Xu Zhuanggong also died in Weiguo, and Xu's land was almost occupied by Zheng Guo's army, and was actually on the verge of annihilation.

Fortunately, not long after this, Zheng Zhuanggong, who was preparing to forcibly annex Xu Guo, died of illness, and Xu Guo finally escaped; As soon as Zheng Zhuang Gong died, Zheng Guo soon fell into a chaotic situation of internal strife among the princes, and Xu Mugong, the successor of Xu State, with the help of Qi State, took the opportunity to return to China, expelled the Zheng army that occupied the country, and restored Xu Guo Sheji.

However, although Xu Guo successfully restored the country, the successive monarchs of Zheng Guo did not give up on Xu Guo, and always wanted to send troops to annex Xu Guo again; In this way, the hatred between the two countries ended from generation to generation, and finally there was the act of Xu Linggong who went to the king of Chu to 'complain' and accuse Zheng Miangong of 'attacking'; the unlucky Zheng Miangong was also reprimanded by the alliance leader Chu Gongwang and imprisoned the doctor next to him as a punishment (it is also said that the king of Chu Gonggong imprisoned Zheng Miangong's younger brother Gongzi - that is, Zheng Chenggong later).

In June of the first year of King Jian of Zhou (585 BC), Zheng Miangong, who had reigned for two years, died; Because Zheng Mourning had no queen, his younger brother 'Gongzi' inherited his elder brother's position as Zheng Bo, which was the thirteenth and fifteenth monarch of Zheng Guo - Zheng Chenggong.

After Zheng Chenggong succeeded to the throne, he was bent on dealing with the 'informer' Xu Linggong, sending troops to attack Xu, and 'seeking justice' for the country and himself; but at this time, Zheng Guo had already been attached to the Jin State Alliance (that is, it was in alliance with Chu State), so Chu State, who thought that he had lost face, hated Zheng Guo's betrayal of the alliance, and sent troops to attack Zheng every year for two years, and every time Zheng Guo relied on the Jin army's southward rescue to relieve himself; therefore, Zheng Chenggong really did not have extra energy at present, to fight with Xu Guo again.

Later, the Duke of Jin Jing moved the capital to Xintian, and designed with the Luan clan and the Zhongxing clan to exterminate the Zhao clan (Dazong), a powerful minister of the Jin State; And there was such a big mess in the alliance leader's country, which made Zheng Chenggong's mind immediately lively; Taking advantage of the internal strife in the Jin State and the lack of external control, Zheng Chenggong secretly went to Dengdi (Yancheng County, Luohe, Henan) in February of the fourth year of King Jian of Zhou (582 BC) to meet with the representative of the king of Chu, Gongzi Cheng of Chu, and resumed exchanges between the two countries. However, Zheng Chenggong still kept an eye on it at that time, and did not immediately swear an oath with the representative of the Chu State, but only promised verbally, and the two countries exchanged contacts and shared news in advance.

Zheng Chenggong's 'betrayal of the alliance' behind the back of the alliance leader (eldest brother) and secretly contacting the Chu State in private was soon learned by Jin Jinggong; Jin Jinggong was naturally furious and disgusted with the traitor (Zheng Chenggong) by repeatedly riding the wall and eating inside and out, so Jin Jinggong was determined to find an opportunity to find Zheng Chenggong to settle the score.

In the autumn of the fourth year of King Jian of Zhou (582 BC), Zheng Chenggong wanted to go to the Jin State to make a pilgrimage to the lord of the alliance, Jin Jinggong, so he led his cronies and close ministers to leave the national capital Xinzheng and marched to Xintian, the capital of Jin; Zheng Chenggong had just left Zheng Guo and arrived at Tonglu (Changzhi Qin County, Shanxi) in the Jin Kingdom, Jin Jinggong, who had been prepared, sent an army to directly capture Zheng Chenggong on the spot, and escorted him back to Xintian and locked him in a prison cell; As a result, Zheng Guo temporarily lost his monarch.

After Zheng Chenggong was detained and imprisoned, Jin Jinggong, who was still angry, immediately sent Luan Shu, the general of the Chinese army, to lead the army to attack Zheng, so as to warn and beat other allies (junior brothers) - the fate of betraying the alliance leader is like Zheng Guo.

At this time, in order to make amends to the Jin State and ask the Jin Jinggong to release the monarch, the ruling ministers of the Zheng State Ziliang and Zihan (both of whom were members of the Seven Mu and the uncle of Zheng Chenggong) and others, sent Zheng Guo's doctor Bo Gong to the Jin State to apologize to the Jin Jinggong in person and ask for peace, asking the alliance leader to forgive Zheng Guo's mistakes and let Zheng Chenggong return to China; If the alliance leader forgives Zheng Guo, then Zheng Guo promised to cut off his personal relations with Chu and continue to stay in the alliance of princes led by Jin State.

The unabated Jin Jinggong did not accept Bo Yan's apology, and deliberately made the situation bigger, so as to threaten and deter the Chu State that dug up his own walls; Therefore, Jin Jinggong ignored the diplomatic etiquette at the time and ordered the execution of Zheng Guo's envoy Bo Bei who came to ask for peace, as a punishment for Zheng Guo's betrayal of the alliance leader.

After learning that the Jin State had detained Zheng Chenggong and killed Zheng Guo's invitation and envoy, of course he couldn't sit idly by and ignore this matter (Zheng Guojun was detained by the Jin State and the envoy was killed, which was the excuse for the war between the Chu State and the Jin State); Therefore, the state of Chu was ready to send troops to intervene and fight with the state of Jin again. However, the king of Chu Gong is relatively 'honest' (or pedantic), and he doesn't want to have a direct military conflict with the Jin State because of his 'secretly digging into the wall', which cannot be put on the table, in that case, the self-proclaimed 'great power demeanor' of the Chu State will be publicly slapped in the face.

So, at the end of the fourth year of King Jian of Zhou (582 BC), Chu Guo, the king of Chu Gong, ordered Yin Zizhong to lead his army to go on an expedition, and successively invaded the allies of the Jin State, Chen State and Ju State, in order to warn and threaten the Jin State, so that Zheng Chenggong could be released (as for whether this has any effect and whether Zheng Chenggong will not be released, the King of Chu Gong does not care, anyway, the attitude of 'aiding Zheng' has been expressed).

Just when the Chu army was attacking Chen and Ju, Jin Jinggong inadvertently met Zhong Yi, the 'Yun Gong' of Chu State, who was imprisoned here, in the official warehouse (military mansion) where military supplies were stored in Xintian, the national capital, during an inspection of the national capital Xintian, which led to an interesting story.

Two years ago, that is, in the second year of King Jian of Zhou (584 BC), when the state of Chu sent troops to attack Zheng (at that time, the state of Zheng had just been attached to the state of Jin, so the state of Chu wanted to attack Zheng), it was defeated by the army led by the army of Zheng Guo's doctor Gongzhong and Hou Yu, and the general of the Chu army, 'Duke Yun' Zhong Yi, who was the rear guard of the whole army and covered the retreat of the whole army, was also captured by the Zheng army, and then was regarded as ' The spoils of war were presented by Zheng Chenggong to Jin Jinggong, the alliance leader who led the army to rescue Zheng, and then when the Jin army withdrew, he also brought Zhong Yi back to Xintian, the national capital, and imprisoned him in the warehouse of the military government, so far he has been a 'Jin prisoner' for two whole years.

When he met Zhong Yi and talked with him, Jin Jinggong admired his demeanor and knowledge very much, so the conversation was very pleasant; At this time, Jin Jinggong was already interested in easing relations with the Chu State.

So, after ending the conversation with Zhong Yi, Jin Jinggong summoned Shi Xie, a general of the Shangjun, and relayed his conversation with Zhong Yi to Shi Xie, wanting to hear Shi Xie's opinion on this matter.

After listening to the monarch's relay, Shi Xie also praised Zhong Yi's demeanor, saying that he was a noble gentleman with good character, and persuaded Jin Jinggong to release him back to Chu and let him serve as an envoy between the two countries to promote the relaxation between Jin and Chu and the resumption of friendly exchanges.

Jin Jinggong followed Shi Xie's advice and soon released Zhong Yi and asked him to return to Chu to serve as an envoy for peace negotiations between Jin and Chu.

After Zhong Yi returned to the state of Chu, he reported to the king of the Chu Gong that the prince of Jin Jinggong intended to ease relations with the state of Chu and the desire of a truce between them; The king of Chu Gong couldn't ask for it, so he appointed Chu Dazai's son Shang (Gongzichen) to go to the Jin Kingdom to respond to Jin Jinggong's truce proposal. In June of the fifth year of King Jian of Zhou (581 BC), Jin Jinggong, the overlord of the princes and the monarch of the Jin State, died (the specific death process will be introduced in detail later), and the prince of Jin Zhou Pu succeeded to the throne, that is, the twenty-seventh Marquis of Jin - Jin Ligong; The historical process of the Jin Kingdom has entered a new chapter.

After Zhong Yi returned to the state of Chu, he reported to the king of the Chu Gong that the prince of Jin Jinggong intended to ease relations with the state of Chu and the desire of a truce between them; The king of Chu Gong couldn't ask for it, so he appointed Chu Dazai's son Shang (Gongzichen) to go to the Jin Kingdom to respond to Jin Jinggong's truce proposal.
