She was reportedly a devoted and virtue wife to Sinjong, whom she advised and assisted in his royal duties,[5] it was said that they two had a good and close relationship each other because of this.
In April 1204, when her husband abdicated and their son, Wang Yŏng ascended the throne as the new King, she was made Queen Dowager.
[4] Even in a very chaotic situation when Gangjong and Gojong ascended the throne, she was admired by their peoples for showing off her dignified appearance as the eldest in the royal family.
This poem, "Everything From the Grand Queen Dowager" (왕태후 만사) was recorded in the 16th volume of the Collected Works of Minister Yi of Korea and it was said that Seonjeong was given the honorary title of "The Supreme Imperial Mother" (태상황모; 太上皇母) during her lifetime, while her eldest son became "Retired Emperor" (상황; 上皇) and her granddaughter became "Queen Consort" (왕후; 王后).
King Gojong praised her effort into the stability of the royal family, rather than getting involved in politics during Goryeo's difficult times.
