One of the manifestations of the collapse of etiquette in the Spring and Autumn Period was the internal strife within the Zhou royal family and the public offices of various countries, and the civil strife between Zheng Guo and the Zhou royal family had just subsided, and the civil strife in Wei had recurred. After the rebellion of Wei Guo in Zhouhu, he welcomed back the son Jin who was exiled in Xing State and ascended to the throne of the monarch for Wei Xuangong. However, this Duke of Wei Xuan did not lead Wei Guo to gain the upper hand in the battle of the princes of the Central Plains, and watched Zheng Guo sit on the position of overlord. Not only that, in the last years of his reign, Wei Xuangong brought a civil strife to Wei Guo that made Wei Guo collapse.

Most of the struggles involving inheritance rights are related to the failure to repair the palace, and the defense of the country is naturally no exception. As early as when Wei Xuangong was a son, he had an affair with his father, Wei Zhuanggong's favorite concubine Yi Jiang, and gave birth to a son, named Qianzi - also known as Lingzi. That is, to cuckold his father, and this news was only known to everyone after Wei Xuangong succeeded to the throne. After the end of the Zhou Hu Rebellion, Wei Xuangong returned to China to inherit the throne and established Yijiang as the main room, and the son naturally became the eldest son. In fact, long before Yi Jiang, Wei Xuangong had already married the daughter of Xing Guojun as the main family, and Yi Jiang was his father's favorite concubine, so Wei Xuangong's move not only violated Zhou etiquette, but also suspected of incest.

However, Wei Xuangong's incest did not end. After the anxious son became an adult, Wei Xuangong married Xuan Jiang, the eldest daughter of the Duke of Qi, as his wife - this Xuan Jiang is the sister of Wen Jiang mentioned above. However, when the bride came to Weiguo, Wei Xuangong saw Xuanjiang's beauty, and he was so moved that he thought of replacing him. used to cuckold his father, and now he has to cuckold his own son, but also, his own son was also brought out by him with a green hat for his own father, which was a big laughing point in the countries at that time.

Wei Xuangong used the excuse to send an urgent son to the Song Kingdom, but he set up a new platform in Qihe and married Xuanjiang as his stepfamily. This is the famous "Xintai story".

After returning to China, he was not dissatisfied with his father's move. However, when you sit behind closed doors, disaster comes from heaven. After Wei Xuangong and Xuanjiang got married, they actually gave birth to two more sons, namely Gongzi Shou and Gongzi Shuo. Originally, the position of the prince of the anxious son benefited from Wei Xuangong's favor for Yi Jiang; At this time, Xuanjiang was favored, Yijiang was neglected, and the position of the prince of the anxious son became increasingly unstable. In addition, in order to make his son a monarch, Xuanjiang blows the pillow wind in front of Wei Xuangong every day, dividing the relationship between Wei Xuangong and Yi Jiang and Anxious Zi. After a long time, Wei Xuangong actually had the intention of killing people and destroying his mouth, and wanted to get rid of the anxious son and set up another son of Xuanjiang.

Although Wei Xuangong had such thoughts, he did not dare to act openly due to the pressure of public opinion, so he discussed a plan with Xuanjiang: first pretended to order the anxious son to send an envoy to the Qi country, but secretly sent assassins to ambush in advance on the road that the anxious son must pass, giving people the illusion of encountering robbers on the road. Anxious did not doubt him, and happily went. However, Xuan Jiang's poisonous plan was known to his son Gongzi Shou.

Although Gongzishou is Xuanjiang's child, he grew up under the care of Wei Xuangong's two younger brothers, known as Zuo and Right. When the anxious son was born, Wei Xuangong, who was exiled, also handed him over to the left and right sons to raise. Therefore, the relationship between the two is very good, although the age difference is very far away, and they are half-brothers, they are still brothers, friends, and brothers, and they are very harmonious. Gongzishou knew that his mother wanted to get rid of the anxious son, so in a hurry, he hurriedly went out of the city in the starry night, caught up with the anxious son who was unaware and gladly sent the envoy, told him what happened, and asked him not to go to Qi and flee to other countries for refuge.

Who knows that the anxious son is benevolent and filial by nature, although he knows everything, he is not willing to disobey his father. He didn't even care about his father forcibly taking his wife, so how could he run away casually? So he rejected Gongzishou's proposal and planned to go to Qi as originally planned. Gongzi Shou, who was eager to save his brother, had to pretend to be a trip for his brother, drunk him in the middle of the banquet, and he rode the convoy of the anxious son and went to death.

Sure enough, when the assassins sent by Wei Xuangong saw Wei Guo's convoy, they mistook Gongzishou for a hurry, and rushed up to kill Gongzishou. And after the anxious son woke up, he found that Gongzishou and the convoy were gone, and he immediately guessed what was going on. So he hurried to the scene of the incident, and saw that the assassin had just killed Gongzishou and was about to leave, so he said loudly: "You have killed the wrong person." I'm the one who is in a hurry! When the Assassin saw this, he simply killed the Anxious Son. I went back to defend the country and returned to my life.

Seeing this, everyone must have felt oh my God, their own brother has given his life for his own brother, and this brother doesn't care about his brother's sacrifice at all, seeing that someone is mourning for this good brother after all.

Because of this oolong incident, Wei Xuangong's conspiracy was still exposed. The spirit of mutual friendship and death of the two sons of the country has also been written into the Book of Poetry by the people of the country and will be sung by future generations, which is the famous "Book of Songs, Wei Feng, and Boat". When Wei Xuangong learned of this, he was moved by the behavior of Anxious Zi and Gongzishou, deeply regretted his actions, and soon died in grief. This event is known in history as the "Xuanjiang Rebellion".

In the Xuanjiang Rebellion, the only one who got the benefit was Xuanjiang's other son, Gongzi Shuo. Due to the accidental death of his brother Gongzi Shou, the identity of the heir of the monarch of the country naturally fell to him. After the death of Wei Xuangong, Gongzi Shuo succeeded to the throne as Wei Huigong. However, because the people of the country were grateful for the virtues of the two sons, most of them did not support Wei Huigong, and the left and right sons, who had raised the anxious son and the son's longevity, hated Wei Huigong deeply, and the two were determined to unite to overthrow Wei Huigong.

Three years later, the left and right sons united with the doctor Ning Kneeling to launch a coup d'état, and supported the succession of Gongzi Qianmu, the brother of the son. The unpopular Wei Huigong had no choice but to flee in a hurry and flee to his mother's country, Qi, to seek refuge. At this time, the monarch of Qi was Qi Xianggong, the son of Qi Xianggong, although Qi Xianggong was shameless, but he was quite ambitious, and he knew that this was a good opportunity to intervene in the affairs of the country and gain benefits and prestige for the Qi country. So he took in his nephew Wei Huigong, and a few years later, he gathered the princes and killed the Weiguo under the banner of Zhou Tianzi. Wei Guo, who had repeatedly experienced civil strife, could not compete with Qi at all, so Wei Huigong regained the position of monarch with the support of Qi Xianggong, and the second son of the left and right was killed, and the son Qianmu escaped for his life because he was the son-in-law of the king of Zhou, and was driven to Chengzhou.

However, Qi Xianggong knew that Wei Huigong's throne was still unstable and there was still a possibility of overturning. In order to bury the power of Qi in Weiguo, Qi Xianggong actually came up with a ridiculous method: he claimed that Xuanjiang was originally going to marry a hurry, but it was only because Wei Xuangong regretted it halfway that it could not be implemented, although so, the marriage contract was still there. Now that the anxious son is dead and Wei Xuangong is no longer alive, this marriage contract should be fulfilled by the other brother of the anxious son, that is, let the prince marry his stepmother Xuanjiang.

In the face of this proposal, which was close to incest, Gongzi resolutely refused, but Qi Xianggong relied on the power of Qi and took advantage of Gongzi's drunkenness to forcibly stuff Xuanjiang to Gongzi and make cooked rice, and the helpless Gongzi had no choice but to obey. Later, the descendants of Gongzi Yan really became the monarch and maintained a close relationship with the Qi State.

It can be said that the ethical relationship in the Spring and Autumn Period and the Warring States Period was too chaotic. First, the daughter-in-law was robbed by her father-in-law, and later her father-in-law's other son married his stepmother. The relationship is too complicated.

From the Zhouhu Rebellion to the Xuanjiang Rebellion, there was frequent domestic turmoil in Weiwei, and it was repeatedly harassed by hostile vassal states, and gradually declined under internal and external troubles. However, the doom of Wei Guo was not over, after the death of Wei Huigong, under the rule of his son Wei Yigong, Wei Guo experienced another disaster of annihilation, although with the help of Qi State to restore the country, but also became a vassal of the great vassal states.

The civil strife of the patriotic country is inextricably linked to the state of Qi. This vassal state, which was located in a corner in the early Spring and Autumn Period, gradually emerged during the reign of the Duke of Qi and began to actively participate in the situation of hegemony in the Central Plains.

On the Shandong Peninsula in the early Spring and Autumn Period, in addition to the Qi State and the Lu State, there was also a vassal state called the Ji State. Although Qi and Ji are neighbors, their relations with each other are very bad. It turned out that as early as the reign of King Yi of the Western Zhou Dynasty, the then monarch of Ji Guo said bad things about Qi Aigong to Zhou Tianzi, and Zhou Tianzi believed it to be true, so he boiled Qi Aigong to death, and set up his younger brother Gongzi Jing as the monarch, which was for Qi Hu Gong. In order to escape the persecution of Ji Guo, Duke Qi Hu even moved the capital for a time. Since then, the two kingdoms of Qi and Ji have formed a deep feud. In the early Spring and Autumn Period, the State of Qi gradually became stronger, and in order to achieve hegemony, it was natural to first target the State of Ji.

At this time, although the country of Ji has gradually been reduced to a small second-class country, the country of Ji, who knows the thoughts of the state of Qi, did not sit still, but actively carried out diplomacy to deal with the state of Qi. In order to protect himself, Ji Guo and Lu Guo became sons and daughters, and later formed alliances many times, trying to take advantage of the contradictions between the two great powers of Qi and Lu to move around. Not only that, but the monarch of Ji Guoguo sacrificed his daughter to Zhou Tianzi to become the queen, trying to suppress the Qi State with the help of the authority of the Zhou royal family. However, in the face of the powerful Qi State, Ji Guo's various diplomatic efforts had little effect.

When the Duke of Qi was in power, the state of Qi began to expand outward. Duke Qi once tried to form an alliance with Duke Zheng Zhuang to jointly crusade against Ji Guo, but for some reason he was unsuccessful, but Duke Qi did not give up. After the death of Zheng Zhuanggong, Zheng Guo fell into civil strife and had a dispute with Song State. Zheng united with the state of Lu, which wanted to mediate the dispute between Zheng and Song, and the state of Ji fought and won the war with the states of Song, Wei, Nanyan, and Qi. In fact, the State of Qi, which stood on the side of Song Wei in this war, originally had an alliance relationship with the State of Zheng, and the reason why he participated in the war was probably mostly due to the reasons of the State of Ji. In the twenty-second year of King Huan of Zhou (698 BC), the ambitious Duke of Qi died with regret of annexing the Ji Kingdom, and his son Gongzi Zhu'er ascended the throne as the Duke of Qi Xiang.

With the political legacy left by his father, Qi Xianggong continued to devote himself to the cause of hegemony. He saw that under the protection of the Lu State, the Ji State could never be destroyed, so he turned against the Lu State. At the beginning of Qi Xianggong's accession to the throne, Lu Huan Gong once wanted to mediate the contradictions between Qi and Ji, so he summoned Qi Xianggong and Ji Guojun to form an alliance, but Qi Xianggong did not buy it, not only did not reconcile with Ji Guo, but immediately sent troops to attack Lu State, and the two sides fought a battle in Xidi. Immediately afterwards, Duke Qi Xianggong invited Duke Lu Huan to go to Qi to officiate at the wedding on the grounds that he would marry the daughter of the same son of Zhou. Lu Huan Gong happily went, but he didn't expect that this trip would cost him his life.

Although Qi Xianggong was quite politically talented, he was extremely inappropriate in his private life. Duke Qi had two daughters, Xuan Jiang and Wen Jiang. Xuanjiang was taken away by Wei Xuangong, triggering the Xuanjiang Rebellion; And Wen Jiang once planned to be married to Zheng Zhaogong, but failed; Later, there was a civil strife in the Lu State, and Lu Yingong was killed by Gongzi Hui, and Lu Huan Gong ascended the throne. In order to stabilize the situation and make friends with other countries, Gongzi Hui expressed his willingness to marry Qi State, make decisions for Duke Lu Huan, and marry Wen Jiang.

Like Xuan Jiang, Wen Jiang was also a famous beauty, and as early as before she got married, she had an incestuous relationship with her brother, Qi Xianggong, who was still a son at the time. The poems "Nanshan", "Edict" and "Zaiqi" in "The Book of Songs: Qi Feng" record this situation.

After Wen Jiang married to the Lu State, he naturally broke off contact with Qi Xianggong and had no contact for more than ten years. Qi Xianggong invited Lu Huan Gong to visit Qi this time, on the one hand, there may be a political strategy of fighting and pulling, and on the other hand, it cannot be ruled out that he will take this opportunity to reunite with Wen Jiang. Wen Jiang naturally knew this, so he not only instigated Lu Huangong to go, but also asked to go with him in the name of Guining. Lu Huangong naturally didn't know the inside story, and was blown by Wen Jiang's pillow wind, so he agreed to Wen Jiang's request. As a result, the brother and sister hooked up again in the country of Qi. Wen Jiang simply didn't return home at night, so he lived in the palace of Qi Xianggong.

When Lu Huan Gong learned of this, he was naturally furious, reprimanded Wen Jiang, and decided to leave the Qi country. Wen Jiang cried to Qi Xianggong about his previous relationship, and Qi Xianggong was angry with his sister and lover, so he didn't do anything and moved to kill people. So, when Duke Qi Xiang said goodbye to Duke Lu Huan, he drunk the latter at the banquet, and ordered his uncle Peng Sheng to drive for him, and took the opportunity to kill Duke Lu Huan on the way. In order to cope with Lu Guo's accountability, Qi Xianggong put all the charges on Peng Sheng's head and killed him as a scapegoat.

Lu Zhuanggong, who succeeded to the throne, was really helpless in the face of this unreasonable uncle, and he had no choice but to acquiesce to the fact that Wen Jiang had left home and never returned. A palace was built for Wen Jiang in the land between Qi and Lu, and Wen Jiang has lived there ever since. What's even more ridiculous is that in order to reconcile with the State of Qi, Duke Lu Zhuang went to the State of Qi again and presided over the wedding of Duke Xiang of Qi and Wang Ji. My own uncle is married to my own mother, oh my God, and this is supported by this mother's own son. In the end, it's all about profit.

The State of Qi had the upper hand in the open and secret battle with the State of Lu, and the so-called cold lips and teeth, Ji Guo was naturally not immune. Seeing that Lu Zhuang Gong had just come to power, Qi Xianggong was too busy to take care of himself, so he freed up his hands to deal with Ji Guo. A year after the death of Duke Lu Huan, the Qi army invaded and occupied the three towns of Ji. Under the pressure of the Qi State, there was also a split within the Ji State, and Ji Ji, the younger brother of the monarch of the Ji State, surrendered to the Qi State and sacrificed the land.

At this time, Lu Zhuanggong still wanted to protect Ji Guo, so he planned to form an alliance with Zheng Guo to fight against Qi State. But at this time, the relationship between Zheng and Lu has long been worse than before. In the civil strife after the death of Zheng Zhuang Gong, the prince who was supported by Gao Qu Mi was killed by the latter during the alliance due to a personal grudge with Qi Xianggong, and even Gao Qu Mi was not spared. At this time, Zheng Guo was in turmoil, and Gongziyi succeeded to the throne not long ago, so he naturally would not rashly settle a grudge with Qi State, so he refused Lu Zhuanggong's request. At this time, Ji Guo was completely cut off, and after another year, the Qi army broke through the capital of Ji Guo, Ji Hou fled, and Ji Guo was declared extinct.

The territory of Qi that annexed Ji increased dramatically, and it suddenly became a powerful force. Under the governance of Qi Xianggong, Qi successively interfered in the internal affairs of Weiguo, sent troops to overthrow Gongzi Qianmu, and forced Gongzi to marry his concubine Xuanjiang, and installed the power of Qi in Weiguo. Later, Qi Xianggong united with the Lu State to attack the Yu State, and became the overlord for a while. However, Qi Xianggong's dream of hegemony did not come true, and it came to an abrupt end because of the outbreak of civil strife. The hegemony of Qi has to be left to future generations to complete.
