According to Yuan He's Genealogy, after Zhou Wuwang destroyed the Shang Dynasty, he established his younger brother (Wang Wen's youngest son) in Kangyi, who was called Kang Shu in the world. Later, the Duke of Zhou (his younger brother) also transferred the surrounding areas of the former Shang Dynasty and seven tribes of the Yin people to Kang Shu, established a patriotic country, and made its capital sing.

Kang Shu spread to the Wei and Qi Dynasties and was bribed to become a marquis. Two generations later, Wei helped to move eastward and became Qi Huangong in the forty-second year of Wei Wugong (77 1 year). During the period of Wu Gong, Wei was relatively strong and politically clear. Wu Gong died in 55, and his son Zhuang Gong succeeded him. Wei Zhuanggong died in 23, and his son Wei Huangong succeeded him.

During the reign of Emperor Gong Xuan of Wei, the sons of Wei competed for the throne, which led to the expulsion of Wei Huigong, who was expelled only three years after he succeeded to the throne in Gong Xuan. Eight years later, Gong Hui revived the country and assembled the Yan State to attack Wang Hui, the king of Zhou. Gong Hui died in 365,438+0, and his son Wei Yigong succeeded him to the throne. Gong Yi is very extravagant, likes cranes and doesn't care about political affairs. In the ninth year of his reign, the Northern Emperor invaded Weiguo, Gong Yi was killed, and Weiguo almost perished.
