Just as Qi was booming, Lu was in a civil strife, and this civil strife was inseparable from Ai Jiang, daughter of Duke Huan of Qi. Duke Zhuang of Lu, the younger brother of Duke Zhuang of Lu, killed two kings of Lu's kings one after another, so it was called the "Qingfu Rebellion".

As the monarch of Lu, Duke Zhuang of Lu was an alternative. Lu was a country that abides and pays attention to Zhou rituals. After Duke Zhuang of Lu took office, he did not act according to the etiquette system, breaking the tradition of Lu's adherence to Zhou rituals, which made the people very disobedient. In the 23rd year of Duke Zhuang of Lu (671 BC), Duke Zhuang of Lu broke the Zhou rituals and held a ceremony for sacrifice to the gods. Duke Zhuang of Lu did not obey the dissuasion of his subordinate Cao Gui after hearing the news, and went to Qi to watch the ceremony regardless of the etiquette system. The next year, Duke Zhuang of Lu went to Qi again, and this time he married Duke Huan of Qi. During this wedding, Duke Zhuang of Lu broke the etiquette system again and even painted the pillars of Duke Huan of Lu's temple red. According to the Zhou rituals, the pillars in front of the temple could only be black.

Before Duke Zhuang of Lu married Ai Jiang, he met Meng Ren. Meng Ren was the daughter of the Dang clan. Duke Zhuang of Lu met Meng Ren by chance and was immediately fascinated by Meng Ren's beauty. So wherever Meng Ren went, Duke Zhuang of Lu followed him. It can be said that he was a person who was more beautiful than beauty. When Meng Ren returned home, Duke Zhuang of Lu also followed Meng Ren's house. Duke Zhuang of Lu became a bloody alliance and promised Meng Ren to make her a wife. Duke Zhuang of Lu and Meng Ren had a son, Prince Pan. Duke Zhuang of Lu married Duke Zhuang of Qi and did not give birth to a son for Duke Zhuang of Lu, but Duke Zhuang of Lu had a son, Gongzi Kai. Duke Zhuang of Lu favored Meng Ren, so he wanted Prince Pan to inherit the throne, but Prince Pan was not the eldest son and could not be established, so Duke Zhuang of Lu had not yet established a crown prince.

After Ai Jiang was not favored by Duke Zhuang of Lu, he had an affair with Duke Zhuang of Lu's younger brother Qingfu. Because Duke Qingfu had an affair with Ai Jiang, his father supported the son Kai, born to Ai Jiang's younger sister Shu Jiang, to inherit the throne. The conflict between Duke Zhuang of Lu and Duke Qingfu was constantly highlighted in this complex relationship, and Duke Zhuang of Lu was also an important reason for the rebellion of Qingfu in the future. In the 32nd year of Duke Zhuang of Lu (662 BC), Duke Zhuang of Lu suddenly became seriously ill and could not be cured for a long time. So Duke Zhuang of Lu began to worry about the inheritance of the throne, so he invited his younger brother to discuss. Duke Zhuang of Lu had three younger brothers, the eldest brother was Qingfu, the second brother was Shuya, and the younger brother was Jiyou. Duke Zhuang of Lu first invited his second brother Shuya to ask who would be more suitable to inherit the throne? Shuya said to Duke Zhuang of Lu: "My father is very talented."

Afterwards, Duke Zhuang of Lu summoned his loyal younger brother Ji You and asked him who he supported to inherit the throne. Ji You said, "I am willing to support Gongzi Ban with death." So Duke Zhuang of Lu told Ji You, "But Shuya just said that Qingfu is very talented." After hearing Duke Zhuang of Lu, Ji You borrowed the order of Shuya to go to the Nenwu family's house to wait for disposal. Then, Ji You ordered someone to send poisonous wine to Shuya and force him to commit suicide. Shuya was afraid that his descendants would be implicated and killed, so he drank the poisonous wine and walked home and died in Kuiquan. After Duke Zhuang of Lu died, Ji You supported Gongzi Ban ascended the throne according to Duke Zhuang's wishes. After Prince Peng inherited the throne, he began to guard Duke Zhuang. But less than two months later, Duke Qing sent a roar to assassinate Gongzi Ban.

There is a reason why Qingfu sent Luo to assassinate Gongzipan. In the year when Duke Zhuang of Lu died, Lu State conducted a rain prayer drill in the courtyard of the doctor Liang family. The daughter of Liang was watching the exercise. After Lu, who was responsible for raising horses, he took the opportunity to tease the daughter of Liang and was discovered by Gongzipan. Gongzipan was very angry when he saw Luzipan's disobedience, so he tied up Liu and beat him. Duke Zhuang of Lu said to Gongzipan: "It's better to kill him, not to whip him. Luo is very strong and can throw the door onto the city wall of Jimen." But Gongzipan did not kill Luo in the end, and Luo also held a grudge against Gongzipan because of being whipped. So, after Gongzipan inherited the throne, Qingfu used Luzi's mentality and powerful ability to plan the assassination of Gongzipan and succeeded.

After Prince Pan was killed, Ji You was afraid that Qing's father would attack him, so he fled to Chen State. After Prince Pan killed Prince Pan, Qing's father supported Gongzi Kai, the son born to Ai Jiang's sister, ascended the throne, and was Duke Min of Lu. In June of the first year of Duke Min of Lu (661 BC), Duke Zhuang of Lu was buried. This was due to the chaos in Lu, so Duke Zhuang of Lu was delayed in the funeral of Lu. In August of the same year, Duke Min of Lu formed an alliance with Duke Huan of Qi in Luogu, and Duke Min of Lu took this opportunity to ask Duke Huan of Qi to help Ji You return to the country. Duke Huan of Qi agreed to Duke Min of Lu, so he sent an envoy to Chen State, and Duke Min of Lu was waiting for Ji You in Lang (now southeast of Qufu, Shandong). Ji You really returned, so Duke Min of Lu praised him. With Duke Huan of Qi's efforts, Ji You was able to return to Lu and made efforts for the stability and stability of Lu.

That winter, Zhongsun Qiu, a doctor from Qi State, came to Lu to comfort the disaster. After that, Zhongsun Qiu returned to the country to meet Duke Huan of Qi and reported on the situation of Lu. Zhongsun Qiu said:

"If Qingfu is not dead, Lu will not be at peace." Duke Huan of Qi asked, "How can we get rid of Qingfu?" Zhongsun Qiu replied, "The disaster in Lu is endless, and Qingfu is just seeking death. The king just needs to wait patiently!" So Duke Huan of Qi asked again, "Can we attack Lu now?" Zhongsun Qiu said, "No, Lu adheres to the Zhou rituals, and Zhou rituals are the foundation of Lu. I heard that, 'A country is about to perish, its foundation must first shake, and then subvert the branches and leaves.' Lu did not abandon Zhou rituals, so it cannot shake the foundation of Lu. The king must take advantage of the current opportunity of Lu's embarrassment and get close to Lu. Be close to polite countries, rely on stable countries, alienate uncoherent countries, and overturn the chaotic countries. This is the way of overlords!"

Although Duke Huan of Qi had already turned Qi into a great power in the Spring and Autumn Period and had become a generation of hegemons, Duke Huan of Qi was not arrogant when dealing with Lu. Instead, he listened to Zhongsun Qiu's suggestions and approached Lu in a crisis, but did not take the opportunity to invade Lu. It has to be said that this was another great contribution made by Duke Huan of Qi, which safeguarded the Lu Kingdom, which respected Zhou rituals, and that was, maintained the principles and disciplines of the Zhou Dynasty.

Later, as Zhongsun Qiu expected, Qing's father once again triggered the chaos of Lu. At the beginning of the second year of Duke Min (660 BC), Duke Min of Lu seized the land of Buqi, but Duke Min of Lu did not take care of it. So on August 24 of that year, Duke Qing sent Buqi to attack Duke Min of Lu in the Wuwei and stabbed Duke Min of Lu to death. Qing's father sent people to assassinate two Lu kings in succession, and knew that he could not escape the blame, so he fled.

After Lu State, he came to Ju State. Then, Ji You took Duke Min of Lu's younger brother back from Duke Min of Lu to Lu State to ascend the throne, and was Duke Xi of Lu. After Duke Xi of Lu ascended the throne, Ji You bribed Ju State and asked them to return Qing's father to Lu State. Ju State agreed to Ji You's request, so he sent Qing's father back to Lu State. When he arrived at Mi (now north of Fei County, Shandong Province), Qing's father sent Prince Yu to ask Ji You for forgiveness, but Ji You refused, so Prince Yu returned to Mi Territory crying.

After hearing the cry of Prince Yu, Qing's father knew the end of his fate and immediately hung his beam to commit suicide. Ai Jiang, who had an affair with Qing's father, wanted to support Qing's father as the Lord of Lu. After Qing's father escaped, Ai Jiang knew about Qing's father's assassination of Duke Min of Lu, and was afraid of punishment, so he fled to the State of Zhu. Later, Duke Huan of Qi felt that Ai Jiang was a shame for Qi, so he sent someone to catch Ai Jiang and kill her on the barbarian land, and then sent her body back to Lu. Duke Xi of Lu buried her body, and the rebellion of Qing's father in Lu was over.

During the entire Qingfu Rebellion, Duke Huan of Qi never favored his daughter Ai Jiang, but destroyed his relatives for justice, and finally killed his daughter, which thoroughly understood the disaster for Lu. It was with the help of Duke Huan of Qi that Lu finally gained stability, restored the etiquette system, and quelled the civil strife.

Before the Zhou Dynasty, the main northern ethnic groups that threatened the Central Plains were Shanrong, Yung, Melon, Tufang, Guifang, etc. Among them, those who lived in the north were called Di, and those who lived in the west were called Rong. In the Western Zhou Dynasty, Guifang and Yuqi became the main powerful enemies that threatened the Central Plains. "The Book of Songs·Xiaoya·Caiwei" mentioned: "Because of the family and family, the family is not in need, and because of the erection, it is because of the erection."

In order to eliminate the powerful enemy and resolve the harassment of Rongdi, the Zhou kings of all dynasties sent troops to conquer many times. Although they had won many victories, the strength of Rongdi was rekindled repeatedly. During the reign of King You of Zhou, the Quanrong was strong and the royal family was in decline. The Western Zhou Dynasty was destroyed by the Quanrong, which forced King Ping of Zhou to move east to Luoyi and rebuild the Zhou Dynasty. At the same time, the Rong tribes were also distributed in the heartlands of the Central Plains, Gansu, Shaanxi, Shanxi and Henan. It was not until the rise of Qin State that the Qin State was developed by Qin Duke and Qin dominated the Western Rong during the reign of Duke Mu, which solved the threat of the Western Rong to the Central Plains.

Due to the decline of the authority of the Zhou emperor during the Spring and Autumn Period, he was unable to call on the princes to resist the Rong and Di together. The Di people invaded the Central Plains more violently. Their forces went east from Shanxi and Shaanxi to Hebei, Henan and Shandong. They took advantage of the opportunity of mutual conquest between the Central Plains to invade the south, posing a great threat to the Central Plains countries. It was in this context that Duke Huan of Qi raised the banner of "repelling barbarians" that the Zhou royal family was unable to raise, and used the excuse of fighting against Rong and Di to unite the princes and revive the world.

The Qishui River in northern Henan and Wei Kingdom in the Wei River area were the largest country among the princes in the northern Central Plains in the early Spring and Autumn Period. The capital was Chaoge, the capital of the Shang Dynasty. As a monarch of a great country in the Spring and Autumn Period, Duke Yi of Wei neither liked to enrich the country and strengthen the army nor expanded the territory. His hobby was to raise cranes. In the palace and the palaces near the capital, there were cranes carefully raised for Duke Yi of Wei everywhere. In order to show his love for cranes, Duke Yi of Wei also specially granted them titles and salaries. The best cranes were equal to doctors, and they could almost get the salary of scholars. There were also special "Crane Generals". Every time Duke Yi of Wei went out to play, they would lead the way in front of the car, like a mighty general.

In 660 BC, the Di people invaded the south in large numbers.

Coming straight to Wei State, Duke Yi of Wei quickly summoned the army to fight, but no one of the soldiers was willing to fight. Because they fought on the battlefield, even if they made meritorious deeds, it would be difficult to get a title. Duke Yi of Wei will only waste financial resources and material resources to win titles to He. These soldiers were very dissatisfied, so they said, "The king will send your general He to fight!" Duke Yi of Wei was helpless and ordered people to let go of all the cranes, barely gather the hearts of the people to gather the army, and then handed the jade ring 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, asking him to lead the army to guard the capital, and instructed earnestly: "Praise the country with this, choose profits."

After Duke Yi of Wei entrusted the capital to Shi Qizi and Ning Zhuangzi, he personally took the battle and ordered Qu Kong to serve as the imperial army to control the chariot for himself; ordered Zibo to be the right of the chariot to protect his own safety; and ordered Huang Yi to be the vanguard and the rear of Kong Ying's palace. At this time, the Di people were already at the city, and Duke Yi of Wei led his people to fight against the Di people in Yingze, outside the capital Chaoge. The guards were uneven and rushed to fight, and they were soon defeated. Duke Yi of Wei was guarding the flag of the Guards and was unwilling to leave, so he was dismembered by the Di people, leaving only a piece of liver.

As soon as Duke Yi of Wei died, no one could stop the Di people. So the Di army attacked the capital of Wei, burned, killed and looted, and destroyed the Wei people. The escaped Wei people were also pursued by the Di people. When Duke Huan of Song came to rescue him, only 730 surviving Wei people were left, plus Gongyi, and the residents of Tengyi had only gathered 5,000. Duke Yi of Wei, the cousin of Duke Xuan of Wei, and the grandson of Duke Xuan of Wei, took away the remaining people, summoned the remaining ministers, and ascended the throne in Caoyi (now southwest of Hua County, Henan). It was known in history as Duke Dai of Wei.

At first, Duke Huan of Qi heard that the Di people attacked Wei State, but did not take it seriously and did not send troops to rescue him. Not long after, he heard that the Wei State was destroyed by the Di people and Duke Yi of Wei was also dead, and then he realized that the situation was serious. He quickly sent his son, Prince Wuqing, to take 300 chariots and 3,000 soldiers to Caoyi to help maintain it. He also gave the horses and sacrificial clothes needed by Duke Dai of Wei, five sets of sacrifice clothes, and gave Mrs. Wei the gorgeous fish cart and Chongjin. In addition, there were 300 cattle, sheep, pigs, chickens, dogs and other livestock, as well as some construction wood. With the support and protection of Qi, Wei State was able to be rebuilt.

However, misfortune never came alone. Duke Dai of Wei died less than a year after he ascended the throne. The Wei Kingdom, which was in ruins, fell into great fear again. At this time, the young master who was exiled to Qi returned to the Wei Kingdom and ascended the throne, known in history as Duke Wen of Wei. At the same time, Mrs. Xu Mu, the sister of Duke Yi of Wei who married into Xu, was heartbroken and was heartbroken when she heard that Wei Kingdom was destroyed. She immediately left Xu Kingdom and returned to Wei Kingdom to help reconstruction. At the same time, she also used her diplomatic talents to run around to collect aid for the reconstruction of the Wei Kingdom.

The reconstruction of the Wei Kingdom was just in full swing, and the iron hooves of the Di people stepped onto the Xing Kingdom again. The year before, the Di people attacked Xing Kingdom, but Duke Huan of Qi was indulging in Yile and was unwilling to send troops to fight. However, Guan Zhong advised: "The wolf of Rong Di should not be disgusted; the intimacy of the summers should not be abandoned. Relaxation and enjoyment are like poison, and should not be greedy. Didn't you hear the Book of Songs say: "Do you don't want to go home, and you are afraid of this Jianshu?" The so-called Jianshu is to warn all countries to jointly resist powerful enemies. Please follow the spirit of Jianshu and send troops to rescue Xing Kingdom." Duke Huan of Qi was enlightened and immediately did not dare to indulge in Yile anymore. He sent troops to repel the Di people and rescue Xing Kingdom.

This time, the enemy ravaged Wei State and then attacked Xing State. If Qi State turned a blind eye, how could he talk about respecting the king and expelling the barbarians? So Duke Huan of Qi invited Song State and Cao State's army to join in Niebei (now Liaocheng, Shandong) to rescue Xing State. However, when the coalition forces arrived, the capital of Xing State had been broken by the Di people. After a large-scale looting, he set a fire to burn the capital.

The coalition forces drove away the Di people and rescued the escaped Xing people, but the capital of Xing had become a ruin and could not be restored. So Duke Huan of Qi ordered the coalition forces to drive to Yiyi, a large population in Xing (now west of Liaocheng, Shandong), to help Xing build the city wall here and build a new capital. With the material assistance from Qi and other countries, the new capital of Xing was quickly built. The people of Xing happily moved into their new homes, and were as happy as if they were going home, so it is known in history that "Xing is like returning home."

Then, Duke Huan of Qi called on all countries to work together to build a new capital for Wei State in Chuqiu (now east of Huaxian County, Henan). The Wei people who lived a stable and peaceful life soon took root in the new land and forgot the pain of the destruction of the country, so it is known in history as "the destruction of the country of Wei State".

Duke Huan of Qi used the important position of Qi among the various vassal states to gradually unite the countries in the middle and lower reaches of the Yellow River to resist the harassment of Rong and Di. Confucius said: "My miniature Guan Zhong, I will be covered with my hair and left-sided lapel." He highly praised the contributions made by Qi to protect the Central Plains culture and the people of the Central Plains from being humiliated. Anlu, saving Xing, and surviving Wei were the three major achievements of Duke Huan of Qi on his way to dominate the world. By summoning all countries to jointly "expel the barbarians", it also laid a solid foundation for Qi to join the nine princes to help the world.
