A study on Yang Taesa' poetry

Yang Taesa(楊泰師) is poet of Balhhe(渤海). This paper was pre-step for a study of Balhae's poetry. Now, when I saw many matirials, Yang Taesa went to Japan that the first man of Balhae people. Yang Taesa was soldier as Guideokjanggun in third king, Mun King. He was soldier but he could make poem. He went to Japan as Busa. Then he wrote some poem, 「Yacheongsdouiseong(夜聽擣衣聲)」 and 「Bonghwagijosingongyeongseolsi(奉和紀朝臣公詠雪詩)」. 「Yacheongdouiseong」 is Gahaengche as 24Gu in the 7Eon. We saw Gubeop, Yeom set up GUsik but Un was unconsistantly. Also, some paragraph was Gubeop of Bu in addition to Hyeo. It was description himself of exclamation. 「Bonghwagijosingongyeongseolsi」 is Chileonyulsi that accord to Gusik in Gyeolgu. Two works are common things, they are up to himself of use Pyeongcheuk' image. He express innocent of everything and descript on directly. 「Yacheongdouiseong」 devide four paragraphs. It accord to Gi, Seung, Jeon, Gyeol of Jeolgu and Suryeon, Hamryeon, Gyeongryeon, Miryeon of Yulsi. Gyeolgu' method is real world-immagination-immagination- real world. Yang Teasa as Sasin listen to Dadeumisori. He listen to Dadeumisori and then associate his wife. He associate to his wife in immation. And lately, He come back again and express his position. 「Bonghwagijosingongyeongseolsi」 is very florid style because he gives to somebody. It is made for Daeu(對偶) of Ssanguidae. He proud on another, he is basement. It is domment in metaphor. Specially, It proper on methapor and simile. If Balhae literature is Korean literature, we include Balhae' poetry. Yang Taesa' poetry is early Korean literature. His poetry is very important works. Because study on his poetry is nessary to early korean poetry. This is meanning of literary history.
