Duke Huan's Gu Qiu would be a league
During the Spring and Autumn Period and the Warring States Period, many leagues and meetings were mostly very happy, and the topics of the meetings were also confirmed. In the Spring and Autumn Period, there was an alliance meeting, three back and forth, the specifications were quite high, the two monarchs personally met, but the alliance did not achieve the purpose in the end, but instead triggered a war. This is not something that the two monarchs can think of.
This matter also talks about the contradiction between Zheng Guo and Song Guo. Duke Zhuang of Song of the State of Song supported the sudden return of Prince Zheng to the throne for the sake of Duke Li of Zheng. Zheng Ligong once promised the Duke of Song Zhuang to become the king of the State of Zheng and then cede the three cities, and gave Bai Bi and gold, and gave the Song Kingdom Tribute Valley every year. It was only when Zheng Ligong successfully returned to China that he repented of his promise, so he asked Lu Huan to reconcile.
This Duke of Lu Huan was a warm-hearted man, and when Zheng Guo's envoys came to visit, Duke Lu Huan "personally went to song and sought solutions for Ru Jun". The State of Lu sent Gongzi Rou to the Song Kingdom to agree on the date of the alliance, and the State of Lu was still quite appealing among the princely states at that time, and the princely state that zhou tianzi was weakened and then truly mastered the pure zhou rites was the state of Lu. Therefore, Song Zhuanggong could not be sloppy, saying, "Since Lu Jun has words and promises, and the widow should bow down to create the Lu Realm, how can he be bothered by the emperor and insulted?" "Judging from the beginning of the alliance, this alliance seems to be a good omen.
The first meeting between the Lu people and the Song people was in the land of fuzhong, and the real protagonist did not appear, perhaps because the Duke of Song Zhuang sent people to Zheng Guo many times to ask Zheng Ligong to fulfill his promises, and the diplomatic relations between the Song State and the Zheng State were in a relatively tense period. Therefore, there was "Lu Hou dai Zheng said thank you, and asked for forgiveness", but the negotiation process was not so smooth. As far as Song Zhuanggong was concerned, the Song State spent national strength and financial resources to support Zheng Ligong, and Zheng Ligong was ungrateful and could not fulfill his promises, which was a big mistake.
In fact, Zheng Ligong did not completely tear up the covenant, but hoped to replace the city with a golden jade valley and temporarily compensate the Song state first. But the contradiction between Zheng Guo and Song Guo is not a substitute for wealth. When Zheng Zhuanggong sent a large army to attack the Song Kingdom, he also sent the Ding of the Song State Sect Temple to the State of Lu, which was a great shame for the Song State. Therefore, when Song Zhuanggong had the opportunity to seize zhengguo city pool and humiliate him, of course, it was the best purpose to occupy Zheng guocheng pool. Even though Duke Lu Huan "could guarantee the ability of a widow" to prove that Zheng Ligong would not renege on his promise, Duke Zhuang of Song asked Duke Lu Huan to persuade Zheng Ligong to cede the three cities as soon as possible, saying that "only the king had already planned for the widow", and the first meeting of Lu Huangong was "remorseful".
For Lu Huangong, this meeting has already given Zheng Guo great face. However, Zheng Guoren's obsession with land was very heavy, and he could not agree with the fact that Zheng Guo ceded land to the Song State, so he took out the Zongmiao Instrument Shang Yi. This Shang Yi was the one who took the initiative to pay tribute to zheng guo in order to negotiate with Zheng Guo in order to obtain a position of scruples. Zheng Guoren took out this thing and prepared to ask Lu Huangong to "return the Song Mansion Treasury to be the Three Cities." In fact, Duke Huan of Lu was already in conflict at this time, but it is estimated that Duke Huan of Lu himself was a monarch who would not refuse, and was entrusted by Zheng Guozhi to personally come to the Song Kingdom and meet with the Duke of Song Zhuang for the second time in the land of Guqiu.
In Zheng Ligong's view, the return of the temple artifacts of the Song Dynasty is equivalent to showing the greatest sincerity, which is determined to establish a long-term alliance with the Song State. But where Song Zhuanggong was the kind of person who gave up, at that time, he was "suddenly discolored" and "his cheeks were red", after all, it was Gu Zuo who talked about him. At this time, the Yan people came to the Song Kingdom again and asked to join the Song State in requesting a request with the State of Qi to protect the society, and it was obvious that the State of Yan wanted to ask the State of Song to be a peacemaker and resolve the contradiction between the State of Yan and the State of Qi. Duke Zhuang of Song took advantage of this to disregard the affairs of Duke Huan of Lu, but instead discussed with the State of Yan. Duke Huan of Lu was of course a wise man, and seeing that Duke Zhuang of Song had no intention of forgiving Zheng Guo, he thought that the State of Qi had a good time to change the subject, and the second Gu Qiu alliance became an alliance between the three kingdoms of Lu, Song, and Yan, and had nothing to do with Zheng Guo at all. It is equivalent to Zheng Guo submitting the agenda, and the result is completely rejected.
After that, The Duke of Song Zhuang did not pay any attention to Lu Guozhi's request, and the supervision of Zheng Guozhi became even more intense, and the Chronicle of the States of the Eastern Zhou Dynasty stated: "Endlessly in the Tao". Zheng Guoren did not have any way after all, and finally looked for Lu Huangong. The biggest problem with Lu Huangong as a person is that he refused once and refused twice, and his face as a monarch has been lost, so there is a third time that Lu Huan Gong should no longer take the initiative to make an alliance with the Song Kingdom. However, Duke Huan of Lu "also asked The Duke of Song to meet in the realm of the false turtle to decide on zheng's affairs." Duke Lu Huan was like this, so was Duke Zhuang of Song, and the two great monarchs seemed to be working Zheng Guo's affairs, Song Gong did not arrive, but only sent envoys to tell Lu Huan Gong: The widow and Zheng have made a pact, and the king should not be with Wen Keye. "This means that there was an agreement between Song Guo and Zheng Guo long ago, and you Lu Guo should not mix." This angered the Duke of Lu Huan, who and Zheng Bo would meet in the land of Wu Father and agree to send troops to conquer the Song Kingdom.
