At a time when the state of Qi was thriving, the state of Lu fell into civil strife, and this civil strife had something to do with the daughter of Duke Qi Huan, Mourning Jiang. After the death of Lu Zhuanggong, Lu Zhuanggong's younger brother Qingfu killed two Lu monarchs, so it was called the "Qingfu Rebellion".

As the monarch of Lu State, Duke Lu Zhuang is an alternative. Lu is a country that abides by and pays attention to Zhou etiquette, and after Lu Zhuanggong took office, he did not act according to the etiquette system, breaking the tradition of Lu Guo abiding by Zhou etiquette, which made the Chinese people unconvinced. In the twenty-third year of Lu Zhuang Gong (671 BC), Qi broke the Zhou rites and held a ceremony to worship the gods. The next year, Duke Lu Zhuang went to Qi again, this time he married the daughter of Duke Huan of Qi. In the process of this wedding, Lu Zhuang Gong once again broke the etiquette system, and even painted the pillars of Lu Huan Gong's temple red, and according to the Zhou ceremony, the pillars in front of the temple can only be black.

Before Lu Zhuang Gong married Ai Jiang, he met Meng Ren. Meng Ren is the daughter of the Dang family, Lu Zhuanggong met Meng Ren by chance, and was immediately fascinated by Meng Ren's beauty, so wherever Meng Ren went, Lu Zhuanggong followed. It can be said that he is a person who is the supremacy of beauty, Meng Ren returned home, and Lu Zhuanggong also followed Meng Ren's house, and then Lu Zhuanggong and Meng Ren made a blood alliance and promised Meng Ren to make her his wife. Lu Zhuanggong and Meng Ren have a son, who is like a son. And Mourning Jiang, whom Lu Zhuang Gong married from Qi State, did not give birth to a son to Lu Zhuanggong, but Mourning Jiang's sister Uncle Jiang gave birth to a son for Lu Zhuanggong. Duke Lu Zhuang wanted to let Gongzi inherit the throne because he favored Meng Ren, but Gongzi was not the eldest son and could not be established, so Lu Zhuang Gong did not establish a prince for a long time.

After mourning Jiang was not favored by Duke Lu Zhuang, he fornicated with Duke Lu Zhuang's younger brother Qing's father. Because Qing's father had an affair with Ai Jiang, Qing's father supported Ai Jiang's sister Shu Jiang's son Kai to inherit the throne. The contradiction between Lu Zhuang Gong and Qing Father is constantly highlighted in this complex relationship, and Lu Zhuang Gong's delay in establishing the crown prince is also an important reason for Qing Zhuang's rebellion in the future. In the thirty-second year of Lu Zhuang Gong (662 BC), Zhuang Gong suddenly became seriously ill and could not be cured for a long time. So Duke Lu Zhuang began to worry about the succession to the throne, so he invited his younger brother to come and discuss. Lu Zhuang Gong has three younger brothers, the eldest brother is Qing's father, the second brother is Shuya, and the younger brother is Ji You. Duke Lu Zhuang first invited his second brother Shuya and asked who would be more appropriate to inherit the throne? Shuya said to Lu Zhuanggong: "Father Qing is very talented. ”

Subsequently, Lu Zhuanggong summoned his loyal younger brother Ji You and asked him who he supported to inherit the throne. Ji You said: "The minister is willing to support the son with death." So Lu Zhuanggong told Ji You: "But just now Uncle Ya said that Father Qing is very talented. After Ji You heard Lu Zhuanggong say this, he borrowed Jun to order Shuya to go to the Needle Wu family's house to wait for disposal. Subsequently, Ji You ordered someone to send poisoned wine to Shuya and forced him to commit suicide. Shuya was afraid that his descendants would be implicated and killed, so after drinking poisoned wine, he went home and died in Kuiquan. After the death of Duke Lu Zhuang, Ji You supported the throne like a prince according to Duke Zhuang's wishes. After inheriting the throne like a child, he began to guard the spirit of Zhuang Gong. But in less than two months, Qing's father sent a person to assassinate Gongzi.

In the year of Lu Zhuanggong's death, Lu Guo conducted a rain prayer drill in the courtyard of the doctor Liang, and the daughter of the Liang family watched the drill from the sidelines, and the person in charge of raising horses saw the daughter of the Liang family, and took the opportunity to flirt with the daughter of the Liang family, and was discovered by the child. Childe-like was very angry when he saw that he was unruly, so he tied him up and whipped him. Lu Zhuanggong said to Gongzi: "It's better to kill him than to whip him." This man was very powerful, and he was able to cast the door leaf on the wall of Jimen. But Childe didn't kill him in the end, and Childe also held a grudge against Childe because of the whipping. So, after inheriting the throne like a child, Qing's father used this mentality and powerful ability to plan the assassination of the child, and succeeded.

After being killed like a son, Ji You was afraid that Qing's father would also poison him, so he fled to Chen State. After Qing's father killed Gongzi, he supported Gongzi, the son born to Jiang's sister Uncle Jiang, to take the throne for Lu Mingong. In June of the first year of Lu Min (661 B.C.), the body of Lu Zhuang Gong was buried, which was due to the civil strife in Lu, so the burial of Lu Zhuang Gong was postponed. In August of the same year, Lu Min Gong and Qi Huan Gong formed an alliance in Luogu, and Lu Min Gong took this opportunity to ask Qi Huan Gong to help Ji You return to China. Duke Huan of Qi agreed to Duke Lu Min's request, so he sent an envoy to the state of Chen, while Duke Lu Min waited for Ji You in Lang (present-day southeast of Qufu, Shandong). Ji You really returned, so Lu Min Gong praised him. With the efforts of Qi Huangong, Ji You was able to return to Lu and made efforts for the stability of Lu State.

In the winter of this year, Zhongsun Xiang, the doctor of Qi State, came to Lu State to express condolences to the disaster, and then Zhong Sun Yu returned to China to meet Qi Huan Gong and told him about the situation in Lu State. Zhongsun Yu said: "If Father Qing does not die, the country of Lu will not be at peace." Qi Huan Gong asked, "Then how do you get rid of Father Qing?" Zhongsun replied: "The disasters in the country of Lu do not stop, Father Qing is just seeking his own death, the king just needs to wait patiently!" So Qi Huan Gong asked again: "Then can you attack the Lu country now?" Zhongsun Yu said: "No, the Lu State adheres to the Zhou rites, and the Zhou rites are the foundation of the Lu Kingdom." The minister heard: 'When a nation is about to perish, its foundations must first be shaken, and then its branches and leaves will be subverted.' 'The state of Lu did not abandon the Zhou rites, so it could not shake the foundation of the state of Lu. The king must take advantage of the current predicament of the Lu country and get close to the Lu country. Approaching a polite country, relying on a stable country, a country that is discordant, and a country that overthrows a disorderly country, this is the way of the overlord! ”

Although Duke Qi Huan had already built Qi into a great country in the Spring and Autumn Period at this time, and he had become a generation of overlords, Qi Huan Gong was not arrogant in dealing with Lu State, but listened to Zhongsun Huan's suggestion, and approached Lu State at the opportunity of Lu State of danger without taking the opportunity to invade Lu State. I have to say that this is another great contribution made by the Duke of Qi Huan, which maintained the Lu State that respected the Zhou rites, that is, the discipline of the Zhou Dynasty.

Later, as Zhong Sun Yu expected, Qing's father once again caused turmoil in the Lu country. At the beginning of the second year of Lu Min Gong (660 BC), Lu Min Gong's teacher seized the Bu Qi field, but Lu Min Gong did not take care of it. So on August 24 of this year, Qing's father sent Bu Qi to attack Lu Min Gong in Wufu and stabbed Lu Min Gong to death. Qing's father sent people to assassinate two Lu Jun in a row, and he knew that he could not escape the blame, so he fled from Lu and came to Ju. Subsequently, Ji You took Lu Mingong's younger brother back to Lu from the State of Lu to take the throne, which was for the Duke of Lu Xu. After Duke Lu ascended the throne, Ji You bribed Ju Guo and asked them to return Qing's father to Lu State. Ju Guo agreed to Ji You's request, so he sent Qing's father back to Lu State, and when he walked to Mi (now north of Fei County, Shandong), Qing's father sent Gongziyu to ask Ji You for forgiveness, but Ji You didn't allow it, and Gongziyu cried and returned to Midi.

After Qing's father heard Gongziyu's cry, he knew the end of his fate and immediately committed suicide. And Wai Jiang, who had an affair with Qing's father, originally wanted to support Qing's father as Lu Jun. After Qing's father escaped, Ai Jiang also fled to the country of Yi because he knew the inside story of Qing's father's assassination of Lu Mingong and was afraid of being punished. Later, Duke Qi Huan felt that Ai Jiang was a disgrace to the Qi State, so he sent someone to capture Ai Jiang and kill her in Yidi, and then sent her body back to the Lu State. Duke Lu buried her body, and the rebellion of Lu Guo's Qingfu ended.

In the entire Qingfu Rebellion, Duke Qi Huan never favored his daughter Mourning Jiang, but killed his relatives in righteousness, and finally killed his daughter, completely understanding the disaster for the Lu State. It was with the help of Duke Qi Huan that the state of Lu was finally stabilized, the etiquette system was restored, and the civil strife was pacified.

Before the Zhou Dynasty, the northern ethnic groups that threatened the Central Plains mainly included Shanrong, Qiyun, meat porridge, earthwork, ghost fang, etc., among which those who lived in the north were called Di, and those who lived in the west were called Rong. In the Western Zhou Dynasty, the ghost side and the Xuan Li became the main strong enemies that threatened the Central Plains. Not to mention the enablement, because of the sting. ”

In order to sweep away the strong enemy and solve the attack of Rong Di, the kings of Zhou have sent troops to conquer many times, although they have won many victories, but Rong Di's strength has repeatedly revived. In the period of King You of Zhou, the dog Rong was strong, the royal family was in decline, and the Western Zhou Dynasty was destroyed by the hands of the dog Rong, so that the king of Zhou Ping had to move east to rebuild the Zhou Dynasty. At the same time, the Rong people also penetrated deep into the hinterland of the Central Plains, Gansu, Shaanxi, Shanxi, and Henan all had the distribution of the Rong people, until the rise of the Qin State, after the development of the Qin Gong in successive dynasties, to the Qin Dynasty of the Mu Gong Qin hegemony Xirong, which solved the threat of Xirong to the Central Plains.

Due to the decline of Zhou Tianzi's authority in the Spring and Autumn Period, he was unable to call on the princes to jointly resist Rong Di, and the Di people intensified their invasion of the Central Plains, and their power from Shanxi and Shaanxi to the east to Hebei, Henan, and Shandong. And taking advantage of the opportunity of mutual conquest between the countries of the Central Plains, they invaded the south on a large scale, posing a great threat to the countries of the Central Plains. It was in this context that the Duke of Qi Huan raised the banner of "Zhengyi" that the Zhou royal family was no longer able to raise, and under the pretext of fighting against Rong Di, he was able to unite the princes and the world.

The Weiguo in the Qishui and Weihe areas in the north of Henan was a relatively large country among the princes in the northern part of the Central Plains in the early Spring and Autumn Period, and the capital was the capital of the original Shang Dynasty. As a monarch of a large country in the Spring and Autumn Period, Wei Yigong neither loved to enrich the country and strengthen the army, nor did he like to expand the territory, his hobby was to raise cranes, in the palace and in the palace near the capital, there were cranes carefully raised for Wei Yigong everywhere. In order to show his love for cranes, Wei Yigong also specially awarded them Juelu, the best cranes are the same as doctors, and they can almost get the Shilu, as well as a special "crane general", every time Wei Yigong goes out to play, let them lead the way in front of the car, like a mighty general.

In 660 B.C., Di invaded the south and went straight to Weiguo, Wei Yigong quickly gathered an army to meet the battle, who knew that none of the soldiers were willing to fight. Because they fought the battlefield, it was difficult to obtain a knighthood even if they made meritorious deeds, and Wei Yigong would only waste financial and material resources to knight the crane, and these soldiers were very dissatisfied, so they said: "The king sent your general crane to meet the battle!" Wei Yigong had no choice but to order people to let go of all the cranes, reluctantly gather people's hearts and gather troops, and then handed over the jade jue to the doctor Shi Qizi, asking him to deal with the country's internal affairs with this, and handed the arrows to the doctor Ning Zhuangzi, and asked him to lead the army to guard the capital. ”

After Wei Yigong entrusted the capital to Shi Qizi and Ning Zhuangzi, he personally put on the battle and ordered Qukong to serve as the imperial commander and drive the chariot for himself; Ordered the son to be the right of the car to protect his own safety; He also ordered Huang Yi to be the pioneer and the queen of Kong Ying. At this time, the Di people had already approached the city, and Wei Yigong led the people to fight with the Di people in Yingze, on the outskirts of Chaoge in the capital. Wei Yigong guarded the banner of defending the country and was reluctant to leave, so he was crushed by Di Ren, and only a piece of liver remained.

As soon as Wei Yigong died, no one could stop the footsteps of the Di people, so the Di army attacked the capital of the Wei country, and destroyed the Wei people after some burning and looting, and the Wei people who escaped were also pursued by the Di people. By the time Song Huan heard the news and rushed to the rescue, there were only 730 surviving guards left, and only 5,000 people had been gathered together with the residents of Gongyi and Tengyi. Wei Yigong's cousin, Wei Xuangong's grandson Shen, cleaned up the remnants of the people, gathered the only remaining ministers, and ascended the throne in Caoyi (now southwest of Huaxian County, Henan), known as Wei Daigong in history.

When Duke Qi Huan first heard that the Di people were attacking the Wei country, he didn't take it seriously, and he didn't send troops to the rescue, but who knew that soon after, he heard that the Wei people were destroyed by the Di people, and Wei Yigong was also dead, only to realize that the situation was serious. Hurry up and send his son Gongzi to Caoyi with 300 chariots and 3,000 soldiers to help maintain it, and give Wei Dai the Duchy of Wei five sets of horses and sacrificial clothes, and give Mrs. Wei a gorgeous Yuxuan chariot and heavy brocade, in addition to cattle, sheep, pigs, chickens and dogs and other domestic animals 300 each, and some timber for construction. With the support and protection of the Qi State, the Wei State was able to rebuild.

However, the disaster is not a single line, Wei Daigong died less than a year after ascending the throne, and the ruined Weiguo fell into great panic again, and at this time, the son of the exiled Qi State returned to the throne of Weiguo, known as Wei Wengong in history. At the same time, Duchess Xu Mu, the younger sister of Wei Yigong, who married to Xu Guo, was so grief-stricken that she immediately left Xu Guo and returned to Wei Guo to help rebuild, and at the same time used her diplomatic skills to run around to solicit aid for the reconstruction of Wei Guo.

The reconstruction of the patriotic country is in full swing, and the iron hooves of the Di people have stepped on the Xing country again. The year before, the Di people had attacked Xing State, but Duke Qi Huan was reluctant to send troops to fight. But Guan Zhong advised: "Rong Di jackal, don't be tired of it; Zhuxia is intimate and cannot be abandoned. Pleasures are like poison, not to be coveted. Don't you hear the cloud of the "Book of Songs": 'Don't you return home, afraid of this simple book.' The so-called brief book is an admonition to all countries to jointly defend against a strong enemy. Please follow the spirit of Jianshu and send troops to rescue Xing Guo. "Duke Qi Huan was like an initiation, and immediately did not dare to delay in Yile anymore, and sent troops to repel the Di people and rescue Xing Guo.

This time, after the enemy ravaged the country, he attacked the state of Xing on a large scale, if the state of Qi turned a deaf ear, how could he talk about respecting the king? So Qi Huan invited the armies of Song and Cao to meet in Niebei (now Liaocheng, Shandong) to rescue Xing. However, when the coalition army arrived, the capital of Xing had been broken by the Di people, and after some large-scale looting, a fire was set to burn the capital.

The coalition forces drove away the Di people and rescued the Xing people who had escaped, but the capital of Xing was in ruins and could no longer be repaired. So Duke Huan of Qi ordered the coalition army to drive to Yiyi (now west of Liaocheng, Shandong), where Xing had a large population, to help Xing build a city wall here and establish a new national capital. With the material assistance of Qi and other countries, the new capital of Xing was quickly built, and the people of Xing moved into their new homes happily, and their mood was as happy as home, so it was called "Xing Qian is like home" in history.

Then, Qi Huan Gong called on all countries to work together to build a new capital for the defense of the country in Chuqiu (now east of Huaxian County, Henan), and the patriots who lived a stable and peaceful life soon took root in the new land and forgot the pain of losing the country, so the history is called "Defending the country and forgetting the death".

Duke Huan of Qi took advantage of Qi's pivotal position among the vassal states, and gradually united the countries in the middle and lower reaches of the Yellow River to jointly resist the attacks of Rong Di. Confucius said: "Micro tube Zhong, I wear the left side of the hair." "He spoke highly of Qi Guo's contribution to protecting the culture of the Central Plains and the people of the Central Plains from being humiliated. Anlu, saving Xing, and preserving and defending are the three major achievements of Qi Huan on the road to hegemony, and by convening all countries to jointly "conquer the country", it also laid a solid foundation for the hegemony of the princes of Jiuhe in the future of Qi State.
