Poeun-Jungmongju who was representative literary man, scholar, politician in the end of Korea Dynasty, shared the fate of Korea Dynasty. He is called the east founder of Sung- Confucianism. Because he ideologically took root in Sung- Confucianism. His poetry is criticized as Hobang(豪放), Juna(典雅), Kyonggun(勁健), Honhu(渾厚), Hwapyong(和平) by the next generation. This is connected with his ideological restraint. In this manuscript I regarded the dignity of Poeun`s poetry as Hobang(豪放), Pyoi(飄逸), Agum(雅健) and investigated cases in each point. Hobang(豪放) means the dignity which comes from the broad-minded and high spirited poet. Pyoil(飄逸) is the elegance of Pyosehanil(표쇄한일). It is the dignity formed when the poet lives alone, and blessed with four properties-Aun(雅韻), Gojung(高情), Chungsa(淸思), Myopil(妙筆). Agun(雅健) is the elegance of Junakyongun(典雅勁健). This is connected with the scholar of refined tastes- Wanghiji(王義之)`s Nanjung(蘭亭), Guyangsu(歐陽脩)`s Naksa(洛社), Bakgeoe(e(白居易)`s Hyangsan(香山). Youhyob(유협) considered Juna(典雅) as the dignity of a confucianist in << Munsimjoryong(文心彫龍)>>. Kyonggun(勁健) is the dignity which is able when the poet observe `Hangun(行健)` in <<Juyeok(周易)>> and `Jonwoong(存雄)` in <<Jangja(莊子)>>. This manuscript is wrote as a part of study of the dignity of Chinese poetry in the end of Korea Dynasty. The comparison the dignity of Poeun`s poetry and the dignity of other poet`s poetry in the same age is leaved as a problem to solve after this.
