Bul-woo-hun Jeong Geuk-In was a man of letters in early Joseon period. He was particularly talented in creation of Chinese poetry. The < Bul-woo-hun-ga>, one of his verses, is handed down to us. As one of the Gyeong-gi-che-ga, the <Bul-woo-hun-gok> is presented by him. And <Sang-chun-gok >, one of his words, is extremely valuable as the first Chinese words. That is to say, Chinese words was initially introduced by Jeong Geuk-In.
A lot of Chinese verses written by him are found in <Bul-woo-hun-jib>, a collection of verses. His Chinese verses include various genres such as Jayeon-si, Doduk-si, Suchng-si and Jeung-si. This study targets Jeungsi, which is written with a purpose for being dedicated to someone. Therefore, if it is examined, his personal relations, thoughts, philosophy and view of life can be identified. It was suggested that he did not make a distinction between Buddhism and Confucianism in that his main subjects of dedication were Confucian scholars, friends, and particularly, monks.
