Princess Jeongsin of the Gaeseong Wang clan (Korean: 정신부주 왕씨; Hanja: 貞信府主 王氏; 1236 – 4 May 1319[a]), firstly called as Princess Jeonghwa (정화궁주; 貞和宮主) or also known as Primary Consort Jeonghwa (정화원비; 貞和院妃), was a Goryeo royal family member as the granddaughter of Duke Yangyang who became the first wife of her third cousin once removed, King Chungnyeol and also the aunt of King Chungseon's 3rd wife.
In 1260, during the first year reign of King Wonjong of Goryeo, she married Crown Prince Wang Sim and became his princess consort (태자비; 太子妃).
After a while, Princess Jeonghwa knelt down and offered a glass of wine to her, but the King turned around and blinked and the banquet ended immediately.
[6] Princess Jeonghwa was then imprisoned in Najang (나장; 螺匠), but with the help of official Yu-Gyeong (유경; 柳璥), she was able to defend herself and be released along with the others who were involved.
There is also a record that she asked a Buddhist monk In Gi (인기; 印奇) to print the Tripitaka Koreana and kept it in Jeondeung temple.
