The State of Qi, which stands on the coast of the East China Sea, is a rich marshal among the princes, and the richness of the State of Qi is incomparable to that of all countries, moreover, the founding prince of the State of Qi, Jiang Ziya, is a god-like figure, and when King Wu of Zhou divided Jiang Ziya, he also granted the State of Qi the right to conquer the country of non-subjects in the east, and the State of Qi was also the first country to dominate, when Jiang Xiaobai, the Duke of Qi Huan, was a mess of cattle. The State of Qi, which has multiple missions and is very good in itself, is so happy in the chaotic world relative to those countries that are anxious and worried about survival, and the geographical environment of the State of Qi is also unique, facing the sea on three sides, except that the west is adjacent to the small countries of Lu, Song, and Wei in the Central Plains, which is easy to defend and difficult to attack. All kinds of advantages made the State of Qi have great self-confidence relative to the countries, and the State of Qi embraced and warmly accepted most of the exiled talents and nobles of the countries.
During the reign of Duke Huan of Qi, Tian Tian, the son of Chen Guo, who was in turmoil in Chen Province, fled to the state of Qi after many hardships, and Xiao Bai treated Tian Guan with great hospitality and gave him a mansion, a luxury car, a beautiful woman, and a large amount of gold and silver. So Tian Guan stayed in the State of Qi, and from tian quan onwards, the Tian family worked diligently for the king of the state of Qi for several generations, and the tian family's efforts were finally affirmed by the monarch, and later Tian Wan's descendant (the fifth grandson) Tian Wuyu was named a doctor, and from then on the Tian family entered the decision-making level of the Qi court.
After Duke Zhuang of Qi was murdered by Cui Zhu and Qingfeng, Cui Zhu and Qingfeng began to attack each other again, and the state of Qi was in chaos. In the end, Tian Wuyu, together with other Qi masters and heavy ministers, quelled the civil unrest, and killed Cui Zhu and Qingfeng, and established a new generation of monarchs, Qi Jinggong, to take the throne. Qi Jinggong ruled the State of Qi for more than 50 years, reusing Yan Bao as a prime minister, and the national power of the State of Qi showed signs of rejuvenation. Unfortunately, after the death of Duke Jing of Qi, the successive generations of monarchs were incompetent and dimwitted, and like the State of Jin, the power of the State of Qi gradually fell into the hands of the four masters of the State of Guo, Gao, Bao, and Tian (a descendant of Tian Wan), and the monarch of the State of Qi slowly became a figment.
The four families of Guo, Gao, Bao, and Tian began a thrilling battle for the power of the State of Qi, and except for the Tian family, all of the four families were the noble families of the State of Qi for generations, only the Tian family was a foreigner, and the foundation was not deep and the weakest. Therefore, the Tian clan implemented the strategy of Taoguang and obscurity, and did not argue with the three families of guogao bao and did not intervene in the war of the three families of guogao bao. At the same time, he bought the hearts and minds of the people of the Qi people. The most incredible thing is that the head of the Tian family, Tian Chang, because of the thinness of the Tian family, actually chose a large number of young and beautiful women to place in his harem, and his guests were not forbidden to enter and leave the harem, which suddenly added more than seventy "sons" to him, and it was with the help of these "sons" that the Tian clan grew rapidly.
Thanks to the three major measures of Taoguang raising obscurity, buying people's hearts and minds, and increasing the number of people, the strength of the Tian family has grown by leaps and bounds. At the same time, the civil war between the three families of Guo, Gao, and Bao caused them to consume a lot of strength and gradually decline. The Tian clan easily wiped out the guo, gao, and bao families, and acquired their fiefs, population, and wealth. At this point, the Tian family had already grasped the military, diplomatic, and political power of the entire State of Qi, and it was only a matter of time before jiang shi became the lord of the state of Qi.
The year 378 BC was the 15th year after the three branches of the Jin Dynasty, and the 15th year of the Warring States Period. Tian He, then chancellor of the State of Qi, banished Qi Kanggong, the last ruler of the Jiang clan, to the coast of the East China Sea and established himself as the monarch. Since it was a usurped country, Tian He did not dare to change the name of the country as blatantly as the Little Tigers (Zhao Weihan), but still continued "Qi" as the name of the country, and the so-called new wine in the bottle was also. This move also united as many people as possible, and counteracted the antipathy of some people who had deep feelings for the state of Qi, and played a certain role in the stability of the new regime. Compared with the change of dynasty of the Jin state, the state of Qi chose a path of "bloodless revolution", and the state of Qi, which had changed its face, had not been weakened in strength, population, and territory, and the "eastern evil" state of Qi was about to enter the stage of the Warring States with a new posture.
