This paper examines the life, literature and art of Kim Deok-hyeong(金德亨) from Gyeongajeon in the late 18th century and early 19th century. In the meantime, there has been mention of his existence, which is excellent in flower painting, but his specific life history or literature such as poetry and calligraphy were not dealt with. Accordingly, in this paper, I tried to comprehensively examine his life and literature by examining various documents that mentioned him, such as 『Naegag-illyeog(내각일력)』, 『Jinhuisokgo(震彙續攷)』, 『Ihyanggyeonmunrok(里鄕見聞錄)』, etc.
 Kim Deok-hyeong’s name received upon reaching adulthood is Kangjung, his pen name is Samyangjae and Hwasanja, and is from the Gimhae Kim family. Kim Deok-hyeong performed the duties of Gakri(閣吏), the secretary of Kyujanggak, among Gyeongajeon, and the duties were passed on to his son Kim Shin-won(renamed Kim Ye-won) and his grandson Kim Geon-shik(金健植). In September 1780, he served as Byeongjo Seori(書吏), and in December 1781, he became Gakri(閣吏), a secretary at Kyujanggak, and served until 1795. He served as secretary at Kyujanggak for a total of 15 years, but as he has been associated with Kang Se-hwang(姜世晃), Shim Sa-jeong(沈師正), Heo Pil(許佖), Choi Buk(崔北), and Kim Hong-do(金弘道) since childhood, he had a chance to sharpen his eyesight. Thanks for this, even after becoming a Gakri, he displayed his special abilities in the field of literature and art. Through his poems such as 『Pungyosamseon』, we were able to get a glimpse of Kim Deok-hyeong's elegant spiritual world and poetic world, and through the records of Ma Seong-rin, who was the same Yeohangin, we confirmed his excellent calligraphy. Through the reviews of Yu Deuk-gong, Park Je-ga, and Yoon Haeng-im, he showed his painting skills, and he showed his special skills in painting rather than writing, and in painting flowers. The fact that he had no choice but to excel in flower painting was also due to his love for and exploration of real flowers. As a result, his teacher, Kang Se-hwang, regarded his flower paintings as treasures and kept them. Through the above research, the existence of Kim Deok-hyung as Yeohangin and the fact that he was a non-professional artist from Suri, apart from being a professional painter of painted books, have given us a glimpse into a part of Yeohang’s culture that promoted late Joseon Dynasty literature.
