Jia Dao, a member of Han Meng's poetry school, is famous for his diligence, and is also called "suburban island" with Meng Jiao. Jia Dao's poems were not famous before his death, and later generations imitated Jia Dao. However, due to the comments of great writers Su Shi and Si Kongtu and the one-sided understanding of this comment, Jia Dao's value orientation as a poet gradually lost its comprehensiveness and impartiality.
Su Shi's evaluation of Meng Jiao and Jia Dao's works in "A Sacrifice to Liu Zi Yu Wen" is characterized by "thin suburbs", that is, there is no essential difference between "cold" and "thin", and they all refer to Meng Jiao and Jia Dao. Both of them have said that their works have a "bitter" style, so in a sense, "bitter" and "cold" have the same effect because. Inspire the style pursuit of "Yuanhe" poetry circle with personalized artistic expression. At the same time, there are also differences between the two works in the attitude towards life and life, the choice of poetic style and the main expressive techniques reflected. The main reason is that Meng Jiao's "bitterness" is not for art, but reflects his poor life and uneven experience in the form of poetry, while Jia Dao deliberately evades reality and treats society coldly, forming a unique bitter style. The style of "Kuyin", represented by two poets, has always stood in the poetry circle in the middle Tang Dynasty with its unique artistic pursuit, which has had a far-reaching impact on the retro atmosphere of later poetry creation and the atmosphere of Confucianism and Taoism helping the world.
