It is a half-portrait of Park Young-am. He is a representative scholar of northern literature in a wide range of fields, including novels, philosophy, astronomy, pathology, and agriculture. He interacted with Lee Duk-moo, Lee Seo-gu, Seo Sang-soo, Yong-gum, and a concessionist, and Park Jae-ga and Lee Hee-kyung frequently entered his house. In the 1780s, the Qing dynasty, which he contacted, greatly influenced his thought system and changed from an accident-related accident to a welfare-related accident.
