A Study on the World of Works by Mumyeongja Yun Ki during the Declaration of silence

The Mumyeong ja Yun Ki made a silent declaration at the ag e of 69 in 1819. 'I won't speak' doesn't mean passive. It is a declaration that 'I will talk about the world through writing' because speaking causes problems. The purpose of this paper is to confirm the will and substance of the work at the time of the declaration. Yoongi had a problematic consciousness about the extreme gap between the rich and the poor in the 18th and 19th centuries, and he suffered from extreme poverty, In particular, at the ag e of 69, he became more critical of the social phenomenon amid a sense of crisis that he was the one who said he would starve to death even after wearing a red patch. After experiencing conflict due to utterance that appears from the age of 50, he finally declared that he would reveal his inner voice through writing at the age of 69. At the age of 69, Yoongi re-established his situation, and his critical attitude toward the world became clearer. He practiced speech about the world through satire on five lazy objects such as lazy scholars, descriptions of 14 old objects such as old scholars, and critical works on eight topics such as and criticized gwageoje(制擧制). In particular, in this year, the critical perception of “money” was revealed in earnest, criticizing the state of the world being exhausted due to “money” symbolized by , , , . The psychological basis of the 69-year-old's declaration of silence, 'Critical attitude and spirit', was later practiced. It is meaningful in literary history and mental history that he kept his spirit and attitude as Poor and Humble Scholars and did not stop his critical voice of the world until the end of the life.
