During the Western Zhou Dynasty, Zhou Tianzi and Zhou Gong divided more than 100 princely states, the vast majority of which were princely states surnamed Ji. After nearly 800 years of annexation, by the end of the Warring States period, only the Warring States Seven Heroes and the Small Kingdom Weiguo remained. So which of these countries is the ji surname? Let's take a look:
First of all, the State of Chu is certainly not a country with the surname Ji. The State of Chu was a state established in the south by the descendants of Gao Yang, and the chu royal family was a surnamed Xiong, which developed in the south for many years and was called "Barbarian" by the Central Plains state. During the Spring and Autumn Period and the Warring States Period, the State of Chu had always been a powerful country, and in the process of participating in the struggle for hegemony in the Central Plains, it had integrated into the Civilization of the Central Plains.
Secondly, the State of Qin and the State of Zhao were not countries with the surname Ji. Qin Zhao was of the same origin as Emperor Zhao, and was a descendant of Dayu's assistant Boyi. The State of Qin is surnamed Ying, and the monarch of the State of Zhao is surnamed Zhao.
Again, Qi Guo is not a Ji surname. The State of Qi was a fiefdom of the Western Zhou dynasty hero Jiang Taigong, and the monarch of the State of Qi was surnamed Jiang. In the early years of the Warring States period, the "Tian Clan Daiqi" incident occurred, and the descendants of the Qi monarch Surnamed Jiang were slaughtered by the Tian family headed by Tian He, and the Tian clan replaced the Jiang clan as the monarch of the State of Qi.
Tian He's ancestor was Chen Guan (also known as Tian Quan), who fled to the State of Qi and took refuge in the State of Qi. Chen Quan was the son of Duke Li of Chen, who fled to the State of Qi because of civil unrest in the State of Chen, and the monarch of the State of Chen was a descendant of Dayu and had the surname of Chen.
Finally, in addition to the above four kingdoms, the remaining Wei kingdoms, Korea, Yan kingdoms, and Wei kingdoms are all descendants of Zhou Tianzi's Ji surname.
The State of Yan was a fief of Zhao Gong, the fourth brother of King Wu of Zhou, and was inaugurated by his eldest son Ke.
Weiguo was a fiefdom of king Wu of Zhou's ninth brother.
The ancestor of the State of Wei was Bi Wan, a descendant of Bi Gonggao. Bi Gonggao was the fifteenth son of King Wen of Zhou, and was given his surname because of his fiefdom in Bidi. Bi Guo died in Xijung during the Western Zhou Dynasty, and his descendants became commoners. Bi Wan was a descendant of Bi Gonggao, who defected to the Jin Dynasty in the early Spring and Autumn Period, was highly valued, and promoted to the rank of Doctor.
The Korean Han clan was descended from King Wu of Zhou and was enfeoffed in Hanwon after moving into the Jin Dynasty.
