Place: State of Xu, originally associated with the Xuchang area in Henan Province
Origin note
A major Xu surname tradition traces the surname to the ancient state of Xu. The state is originally associated with the Xuchang area in today's Henan Province, while later Spring and Autumn records show Xu under pressure from neighboring states. In surname use, Xu should therefore be read as a state/place surname layer first; the modern meanings 'allow' or 'promise' belong to the character meaning layer, not the origin story.
