It was successfully separated and eventually annexed by Lu. There are two disasters: 1 and the three-ring attack, which is the private counter-bureau. At the end of the Spring and Autumn Period, Lu's health became weaker and weaker. At that time, Wu Yue became more and more powerful. Lu Jun hoped to use the relationship between wuyue and wuyue to contain Qi and the Third Ring Road, but in vain. In 487 BC, in the eighth year of mourning for the public, Wu (Zhu) cut Lu to the city gate and left the League. At the same time, come and cut, and take three cities. In ten years, southern Xinjiang entered Faqi. In the eleventh year, Qi attacked Lu again. In 473 BC, Ju Jian, King of Yue, destroyed Fu Cha, King of Wu. At this time, Aigong suffered from Sanhuan, and Sanhuan also suffered from Lu Gong. Yuling went to Osaka on business and met Meng in the street and said, "Will I die?" Right: "I don't know." Many people tried to cut down the Third Ring Road with Yue, and the Third Ring Road also attacked many people, and many people rushed to Wei and Zou, and then rushed to Yue. Chinese people came back from mourning. He died soon after.

2. "Accompany the minister in national life", that is, the minister's rebellion. At the end of the Spring and Autumn Period, the surname Ji actually replaced the political power of Lu. Until Lu's death, although Lu Jun still existed, he did not split up like Jin and Tian. However, Lu's "accompanying ministers in national life" is the most prominent phenomenon in China's vassal states. Confucius said, "Accompany the minister in the life of the country, and don't lose the hope of the third generation." These three generations can be said to be dominated by Zhao Gong, Ding Gong and Ai Hong. Fei, Shi Dezhi and Lai are the fiefs of these three families. Later, the three tribes expanded separately, occupying more and more land, and the city circle of the city became thicker and thicker, equal to or exceeding the cities (countries) of the princes. Therefore, Ji, Meng and Shu rebelled against the princes according to the city, and later the officials of the doctor rebelled against his "master" according to the city (the officials called Dr. Qing "master", which means master). In 537 BC, Shu Niu rebelled against his uncle Sun Shi. The rebellion of courtiers began. Due to the lack of aristocratic support, the vertical cow soon failed. As a result, uncle Sun (the illegitimate child of Mu Shu) ascended the throne. In 530 BC, Nan Kuai launched a rebellion, and uncles, Zi Yi and others also participated in the rebellion. When General Nan Kuai launched a rebellion, everyone laughed at him and made up a song saying, "Some people become arrogant when they become retainers!" " Ji's army surrounded Fei Tuan and could not get in. Therefore, Ping Zi hated Ren Fei, and when he caught Ren Fei, he was put in prison. Uncle Gong suggested: "If you see people wasting money, those who are cold wear clothes and those who are hungry eat, making you a master, exhausting you, and spending money back, Heather will die!" Therefore, it is necessary for people to change their attitudes and tend to be awkward. In 528 BC, in the 14th year of Zhao Gong, Nan Kuai wanted to form an alliance with Ren Fei in order to get the support of Ren Fei. When you join the league, take someone to rob the South Express. Later, he fled to Qi. Qi Jinggong has great ambitions for Lu, so the rebels of Lu often take refuge in Qi, which has almost become a "outlaw". Qi Jinggong said to Nan Kuai, "Rebellion?" Nan Kuai replied, "I want to open my office." The son of Dr. Qi said: "It is a great sin for the minister to open a public office!" It can be seen that rebellion against ministers is opposed by nobles. In 500 BC, in the tenth year of Ding Gong's reign, Uncle Sun Shi, a courtier, committed treason. The enemy of an uncle, why not lead the troops around Thailand, for a long time without success. The harem wanted to exchange places with Qi, but the people refused, so they besieged the harem. Hou ran away in fear.

As mentioned above, the retainer is a noble housekeeper. Even if you are not a slave, you are from humble origins. For example, Nanyi, Nankuai and Yanghu are not nobles. Therefore, the rebellion of domestic ministers shows that the patriarchal feudal system based on blood relationship is disintegrating day by day, which leads to the decline and transfer of political power. At that time, Confucius was Lu Sikou, who advocated "opening the government" (expanding the government). When a private person resists public office, he stands on the side of public office and opposes the private person. When the retainer rises up against the private soldiers, he opposes the retainer. Therefore, he once put forward the political slogan of "capturing the three capitals". At first, the three families agreed to suppress the rebellion of the retainer. But Sandu was really destroyed, and the three tribes lost their base areas, so they all changed their minds later, so the plan to capture Sandu finally failed and never came true.
