At the end of the Spring and Autumn Period, the Zhou royal family declined, and some larger vassal States attacked each other for power, among which Qi was the strongest. During Qi Xianggong's reign, politics was dark and contradictions within the ruling class were sharp, so Qi Xianggong's brothers and ministers fled abroad. Childe Xiao Bai and Miyako Jiu also went abroad to find a political way out. Gong Zijiu's mother is the daughter of the king of Lu, so Guan Zhong accompanied Gong Zijiu to Lu, while his son hid in Cao Jun under the protection of Bao. After twelve years of civil strife in Qi State, Miyako Jiuhe, who fled abroad, wanted to take this opportunity to regain the throne. After receiving the letter, Gongzi and Bao set out early. Miyako learned for a long time that Childe Xiaobai was on his way, so he sent Guan Zhong to ambush on the road, ready to sneak attack Childe Xiaobai. When Xiao Bai's flying horse arrived, Guan Zhong shot at Xiao Bai with a bow and arrow, and Xiao Bai let out a cry and fell dead. Guan Zhong mistakenly thought that Xiao Bai was dead. In fact, Xiao Bai, the son, was only slightly injured, and his life was not in danger. Gongzi and Bao arrived in Qi yesterday and became the monarch of Qi, which is also famous in history. When Guan Zhong and Gong Zijiu knew that their son was not dead, they asked Lu to help them attack Qi, hoping to regain the throne. In the battle, Lu was defeated, Miyako was killed for a long time, and Guan Zhong was put in a prison car and sent back to Qi. Bao and Guan Zhong were good friends when they were young, and their friendship has always been deep. When they arrived at the border of Qi, Bao released him from the prison car and persuaded Guan Zhong to help the rich countries of Qi. Guan Zhong had the great ambition of "ruling the country and leveling the world", so he agreed. Qi Huangong has always held a grudge against Guan Zhong, because he shot an arrow and wanted to put Guan Zhong to death. However, after repeated recommendation by Bao, he also cherished talents very much and left Guan Zhong behind. After Qi Huangong reused Guan Zhong, he was often asked about state affairs. Qi Huangong asked Guan Zhong about Qiang Bing, a rich country. Guan Zhong replied: "To make the country rich and strong, we must first appease the people's hearts. To win the hearts of the people, we must first cherish the people. If the monarch can cherish the people, the people are naturally willing to contribute to the country. If you cherish the people, you must first make them rich. After the people are rich, the country will be well governed. " He also said: "There are not many soldiers. Soldiers must have strong combat capability and high morale. When morale is strong, the training of the army will be better. " Qi Huangong appreciated Guan Zhong's theory that Qiang Bing, a rich country, has made great achievements. Guan Zhong was soon appointed Prime Minister, ranking above Bao. Bao was not jealous of Guan Zhong, but assisted with Guan Zhong and Qi Xin. Guan Zhong said with emotion: "My parents were born, and only Bao Shu Ya really understood me." This is the famous "friendship between Bao and Guan" in history. With the help of Guan Zhong, Yong, Sui and other countries were destroyed, and other vassal States recognized the hegemony of Qi. In 645 BC, Guan Zhong, who made immortal contributions to Qi Huangong's reign as king, died. After Qi Huangong lost Guan Zhong, he reused treacherous court officials, the regime was chaotic, and the country slowly declined. In the end, even he was harmed by treacherous court officials and lost his hegemony.
