In 723 BC, Duke Lu Hui died, and his son Xigu became the regent of the king, and he was the Duke of Lu Yin. According to the Zhou ceremony, the monarch did not change the Yuan when he ascended the throne, so 722 BC was the first year of Lu Yin, and the Eastern Zhou Dynasty entered the Spring and Autumn Period in this year.

This year is the forty-ninth year of King Ping of Zhou, the twenty-second year of Duke Zheng Zhuang, the ninth year of Duke Qi Xi, the second year of Marquis of Jin, the eleventh year of Quwo Zhuangbo, the forty-fourth year of Duke Wen of Qin, the nineteenth year of King Wu of Chu (thirty-one years changed to the title of king), the seventh year of Duke Mu of Song, the thirteenth year of Duke Wei Huan, and the twenty-third year of Duke Chen Huan.

There are still about ten years before the birth of Duke Qi Huan, forty years after the Qin Mugong and Song Xiang Convention, fifty years after the Jin Wen Convention, about eighty or ninety years for King Chuzhuang, one hundred and seventy-one years for Confucius, and about two hundred and twenty years for Zhao Xiangzi.

Spring and autumn are broadly divided into three phases.

The first stage, the first year of Lu Yin - the twenty-seventh year of Lu Xi Gong (BC722-BC633). The main characteristics of this period were the gradual decline of royal power, the loss of power by the Son of Heaven, the rise of princes, and the unscrupulous annexation of small states by large countries in order to compete for hegemony; The strength of the barbarian Rong Di was greatly enhanced, and he continued to invade and squeeze Huaxia, and even destroyed Xing and Wei for a time. The representative figures of this period are Zheng Zhuang Gong, Qi Huan Gong, Chu Wu Wang, Chu Wen Wang, Chu Cheng Wang, Jin Xian Gong, Qin Mu Gong.

In the second stage, the twenty-eighth year of Lu Xun Gong - the twenty-sixth year of Lu Xiang Gong (BC632-BC547). In the twenty-eighth year of the reign of Lu Xu, the Battle of Chengpu broke out in Jin and Chu. In the more than 80 years that followed, the two superpowers repeatedly competed for hegemony in the Central Plains. The former tyrant Zheng Guo was tragically ravaged, and the land of China was without war for many years. The representative figures include Jin Wen Gong, Jin Jing Gong, Jin Mourning Gong, Chu Mu Wang, Chu Zhuang Wang, and Chu Gong Wang.

The third stage, the twenty-seventh year of Lu Xianggong - the thirteenth year of Lu Mourning (BC546-BC453). In the twenty-seventh year of Lu Xianggong, the Chinese princes led by Jin and Chu held a "Soldier Killing Conference" in the Song State. The participating countries signed a peace treaty, and the relations between Jin and Chu were normalized, and no major conflicts broke out between the two countries since. However, since then, the princes have begun to lose power, and their power has further declined, and the emperor has gradually taken control of the state power by usurping the monarch. Among them, typical ones are Lu Guosanhuan, Jin Liuqing, Qi Guotian, Zheng Guoqimu and so on. The state of Chu was defeated by the emerging state of Wu and declined, the state of Wu was short-lived and destroyed by the state of Yue, and the former overlord of the Jin state was repeatedly attacked by the princes of the Central Plains and began to split, until the thirteenth year of the Duke of Lu mourning, "Zhao, Wei, and Han three families divided into Jin", and Chinese history entered the Warring States Period. At this time, the representative figures were Wu Wangfucha, Yue Wang Goujian and the prominent ministers of various countries.

In the first year of Lu Yin's reign in Hexi, the "chicken blood effect" of the Qin people tended to intensify: the Duke of Qin Wen led the Iron Curtain chariot to collide with Xirong's strong-bowed and fast horses.

The Jin people in Hedong threw themselves into the vigorous infighting movement with great enthusiasm, and the two factions of Jiangdu and Quwo were inseparable.

The Central Plains is relatively calm, and the people of Chen and Cai are spending their last, carefree and happy moments; And Zheng Guo is brewing a big civil strife.

The arrogant and belligerent Lu Huigong offended the surrounding countries, and then died contentedly. During the reign of Lu Huigong, wars broke out between Lu and Qi, Song, Zheng, Di and other countries, and the countries regarded Lu Huigong as a ruin. Lu Huigong left his successor with two messes, one of which was poor foreign relations.

The Qi State was not too strong at this time. The surroundings of Qi were full of enemies, and life was quite difficult: the Ji Kingdom in the east (in the area of present-day Shouguang) had a feud with Qi, and Beirong also constantly invaded the border of Qi; And the people who hate Qi the most are none other than Lu Huigong. Lu Huigong intermarried with Ji Ren and formed an alliance with Beidi, and he used various means to win over the anti-Qi forces; These three forces are like three-clawed steel tongs, firmly imprisoning the Qi State.

Wei Guo was not only in-law with Qi Guoshi, but also a traditional ally with Lu (the close friendship between the two countries stemmed from the deep brotherhood between Zhou Gongdan and Wei Kangshu), Wei Hou did not want to see the two countries fighting, so he stood in the middle of Qi and Lu and the mud.

The Jingchu giant crocodile in the south is slowly crawling down the river, and many small countries in the Jianghan Valley are gradually feeling the threat of the coming Chu State.

Lu Huigong's wife had no offspring, and one of his concubines gave birth to a son, Xigu. When Aunt Xi reached the age of marriage, Hui Gong married Princess Zhongzi for him in the Song Kingdom. This princess of the Song Kingdom has the beauty of the country and the city, and as soon as Lu Huigong saw her, he broke out in an instant, and he immediately brought his prospective daughter-in-law into his bedroom. After October, Nakako gave birth to Gongzi Yun. Hui Gong then made Zhongzi his wife and Gongzi Yun as the prince.

Hui Gong wreaked havoc on Zhou Li, sowing the seeds of turmoil for the political situation of the Lu State. Before he died, he summoned Aunt Xi and his two younger brothers, Gongzi Yan and Gongzi Hui, and said: "King Wu died early, and King Cheng was young; The Duke of Zhou was then the regent and proclaimed the king, and when the king became an adult, he canceled the regent and returned to the king; The virtues of the Duke of Zhou were praised by the world. Now that the prince is young, Lu Guo will hand it over to Aunt Xi first. Xigu is the regent of the king, but you must not forget the virtues of the Duke of Zhou, and you will return the state government to the prince when the prince becomes an adult! This is the second mess left by Lu Huigong.

The identity of Lu Yin is very special, as a regent, he is not a monarch in the full sense of the word (so much so that when the princes and ministers came to mourn Hui Gong, he did not dare to come out to meet as the main mourner), but he still enjoys his own era name and nickname, which shows that he has a legitimate monarch status.

The first sentence of "Zuo Biography" is "...... (Lu Yin Gong) does not book the throne, and takes it. The "Spring and Autumn Period" began with such a strange event.
