She is a descendant of the Wang family, belonging to the Wang Tiantu lineage.

She encounters Wang Lin at the Wang family ancestral home while returning to the Zhao Kingdom to pay respects to their ancestors. She claims to be a descendant of her fourth uncle. Wang Lin uses magic to cure her illness and gives her a life-saving jade slip to ward off external enemies. He also sets up a defensive magic array for the Wang clan.
