Passage: In the Chinese folk religion, the river is protected by the "Xiang River goddesses" or "Xiang Consorts" Ehuang and Nüying. They are said to have been the daughters of the legendary ruler Yao and the wives of his successor Shun. Unable to bear the pain of their husband's death, they committed suicide in this river.
