This encyclopedic work of agriculture written by Hong Man-seon (1643-1715) deals with almost all the subjects related with farming and life in rural areas, including housing, food and health, farming, and gardening. The book is highly regarded for the comprehensive practical knowledge it contains for the benefit of farm households, and had a significant influence on other scholars including Yu Jung-rim (fl. 18th c.) and Seo Yu-gu (1764-1845).
