Seonhwa's existence is controversial due to the discovery of evidence that points to King Uija's mother as being Queen Sataek, and not Seonhwa as indicated by historical records.
Seonhwas eksistens er omstridt efter, at man skal have opdaget beviser, som tyder på, at Uijas mor var Dronning Sataek, og ikke Seonhwa, som det er i de historiske kilder.
