The future Princess Deoknyeong was born in Yuan dynasty with the name Borjigin Irenchenppan (보르지긴 이렌첸빤; 孛兒只斤 亦憐眞班) as the daughter of Chopal.
[3] Then, in 1337, she gave birth to their first son, the future king Chungmok of Goryeo and also a daughter, Princess Jangnyeong.
[4] When Chungmok died without leaving any successor, Chunghye's other son from Consort Yun ascended the throne as King Chungjeong.
Knowing that Yun Si-u (윤시우) and Bae Jeon (배전) formed a dominant force which caused political disturbances, Deoknyeong formally stepped down as regent in 1348.
[3] In 1367, her homeland gave her the Imperial title as Princess Jeongsunsugui (정순숙의공주; 貞順淑儀公主)[1] and she died on 15 April 1375.
