At that time, troops were sent to destroy Wei, and the main force to destroy Wei was Minister Bi Wan. Later, Jin Xiangong gave the land of Wei to Bi Wan. From then on, the descendants of Biwan took Wei as their surname and became the largest Wei family in Jin. With the rapid development of Jin, Wei also developed rapidly and became one of the six surnames of Jin. Later, Wei joined other surnames to destroy the gold, and Wei was called Wei.

At that time, the founding emperor of the Western Zhou Dynasty named the vassal as the most popular name, and one of the vassal named Ji was called the fief, so Wei State was established, which was the first Wei State in history. However, due to the long time and the imperfect historical records at that time, there was no clear record of the surname of the emperor of Wei at that time, but one thing is certain, this Wei was a vassal sealed by the emperor and other countries, and it was called "Wei of the Western Zhou Dynasty" at that time.

During the Spring and Autumn Period, the State of Jin, which was second only to the State of Wei in the Western Zhou Dynasty, began to expand its territory, and the State of Wei, which was closest to the State of Jin, became the object of expansion. In a few years, the State of Jin destroyed the State of Wei. At that time, the general who led the soldiers to capture Wei was Bi Wan. Later, Jin Xiangong gave Bi Wan the land of Wei. Because it used to be the land of Wei, Biwan's descendants changed their surnames to Wei, becoming one of the six surnames of Jin at that time.

At that time, Jin developed very rapidly because of the expansion of land, and Wei also developed with Jin. Within a few years, Wei joined forces with other surname families to destroy the State of Jin, and the emperor of the State of Jin became a puppet of the surname family.
