Xu

The surname Xu (徐) is a prominent Chinese surname with a history spanning over 3,000 years. Its origins are deeply rooted in ancient Chinese states and noble lineages. The name is often associated with the state of Xu, which existed during the Western Zhou Dynasty and Spring and Autumn period in what is now modern-day Anhui and Jiangsu provinces. Descendants of the ruling families of this state adopted Xu as their surname. Over centuries, the surname spread throughout China and beyond, carried by migrants and through various historical events.

Beyond its historical roots, the character '徐' itself can also be used as a given name, though less commonly than as a surname. When used as a given name, particularly in modern contexts, its meaning can be interpreted more broadly, often evoking images of slowness, leisure, or tranquility, as well as the more poetic 'dawn' or 'rising sun' depending on the specific character combination or context. The surname Xu is particularly prevalent in southern China and among overseas Chinese communities.
