During the rule of the Qianlong Emperor of China, correspondents from the Joseon Dynasty of Korea were continuously sent to Beijing for study and exchange purposes. Among those sent was the famous Kim Jeong-hui (1786-1856). Not only was he highly proficient in the classics and in epigraphy, but he was also an acclaimed calligrapher who had followed Emperor Joseon on his diplomatic ventures to Beijing during the rule of Emperor Jiaqing. Thus, Kim Jeong-hui received Weng Fanggang as a teacher, and was influenced by him regarding both the classics and poetry criticism. This study aimed to explore the influence of Weng Fanggang's poetry criticism on Kim Jeong-hui, starting by describing the two men's poetry-related exchanges and subsequently discussing their relationship of inheritance in the field of poetry from two perspectives: (a) the study of poetry and (b) emphasis on learning and temperament. In doing so, we discovered that Kim Jeong-hui's standpoint regarding the study of poetry was essentially identical to that of Weng Fanggang. Kim Jeong-hui's philosophy was to approach what is distant by first studying what is close. Therefore, he studied the poetry of the Song and Yuan Dynasties before studying that of the Tang Dynasty, and the works of Su Shi and Huang Tingjian before those of Du Fu. He appreciated "learning that is poetry" while opposing romantic poetry, which is not practically anchored. He emphasized spirituality but also stressed the need for learning and moral cultivation; therefore, he did not appreciate the frivolous and trivial spiritual poems of Yuan Mei.
