In Sukjong, he was admitted to the office of public servants and went through several official offices. In 1726 (Yeongjo 2nd year) He was originally a connoisseur, but he was always interested in epidemiology and had a lot of knowledge in epidemiology. According to his book, "Ephemeral Twenties," he claims that the stars are circling the sun and that the earth rotates 366 times a year around the South Pole and the North Pole. He also argued that human history, civilization and natural phenomena have a certain cycle. However, his argument did not attract much attention at the time, and later influenced Lee Kyu-kyung and Hongdae Yong.
