Shin Saimdang, the only woman in Korean history to be designated as a person of currency, has existed as an image far from reality. Shin Saimdang, recorded as a painter of the time when he survived, was recognized in the 18th century as the mother who gave birth to a great character named Yulgok. After the 1900s, she was introduced as a representative of educated women in the modern period, and during the Japanese colonial period, she was introduced as a mother of the military. After liberation, it became a female figure celebrated at the national level as the epitome of wise mother. It is time to reconsider a more accurate perception of Shin Saimdang, which has long been used in women's education and is the only female character in currency who still exerts popular influence. In this paper, I would like to examine how the image of Shin Saimdang has changed to form Shin Saimdang discourse, and suggest how Shin Saimdang can be presented in the current textbook and in the future.
