Meaning: The surname 蔚 (Wèi) originates from two main sources. Firstly, it derives from the Zhou Dynasty (1046–256 BCE) when Ji Tu, a minister of the Jin State, was granted the fiefdom of 蔚 (Yù) in present-day Shanxi Province. His descendants adopted 蔚 as their surname. Secondly, it also originates from the Xianbei people, an ancient nomadic group, who adopted the surname during the Sinicization process.
With roots in ancient China's Zhou Dynasty and the Xianbei people, the surname 蔚 is tied to a fiefdom in Shanxi and symbolizes a type of grass known as mugwort.
