She was born in 1185 and in 1199, she formally became a Princess (공주, 公主) when her older sister, Princess Hyohoe, died at 17 years old.[3] Later, in 1201, she married Wang Jeong (왕정) and was given royal title Count Siheung (시흥백),[4] later becoming Duke Hoean (회안공).[5] Her husband was the brother of Queen Seongpyeong, the second wife of King Huijong making them in-law’s. With Wang Jeong, she had 3 sons[6] and their second son later married Princess Suheung who was her grandniece.
