The dividing line during the Spring and Autumn Period and the Warring States Period was that the three ethnic groups were divided into the Jin State, that is, the three ethnic groups originally belonging to the Jin State carved up the independence of the Jin State, namely Zhao, Wei and Han. Therefore, Zhao, Wei and Han are the latest of the Seven Heroes in the Warring States Period, and they are neck and neck. In 403 BC (the 23rd year of Zhou Weilie), Zhou Weilie established three princes. Western merchants enfeoffed governors, including Yan and Qi, and Yan remained unchanged from generation to generation. Therefore, the seven chivalrous men were originally the state of Yan, 1044 BC, followed by the vassal state of Chu (1043- 102 1 year ago), and then the state of Qin. He's a little special. Jiang Ziya, the ancestor of Qi, became a vassal at the same time as Yan, but his style was eventually replaced by Tian, who was called Tian. In 386 BC, Tian He was listed as a vassal and replaced by Tian Qi. Tian He was officially called Hou and still used the same name, which appeared at the latest in the Warring States Period.
