Jia Dao is from Zhuozhou, Hebei. In his early years, he was poor and became a monk, and his Buddhism was unknown. He once lived in Shi Cun, Shiyukou, Fangshan, but left Jia. 19 years old, traveling around the world, knowing Meng Jiao and Han Yu. After returning to the secular world, scholars were introduced repeatedly. Tang Wenzong was the main book of the Yangtze River at that time, so he was called "Jia Changjiang". His poems are good at carving, and he likes to write desolate and lonely places, full of bitterness and feelings. He claimed to be "two sentences in three years, one song and two tears". The Collection of the Yangtze River 10 volume contains more than 370 poems. In addition, there are 3 volumes of small collections and 1 volume of poems.

Jia Dao, known as "the prisoner of poetry" and "the slave of poetry", did not like to associate with ordinary people all his life. Biography of Talented Talents in Tang Dynasty called him "a man who knows the world". He only likes to write poems and mourning poems and work hard on words.

Editing this life, he became a monk in his early years, and Jia Dao became a monk in his early years without a name. In the winter of the fifth year of Yuanhe (8 10), I went to Chang 'an and met Zhang Ji. The following spring, I went to Chang 'an, visited Han Yu for the first time, and deeply appreciated my poems. After secularization, scholars were introduced repeatedly. When he was literate, he was demoted to the main book of the Yangtze River (now Pengxi, Sichuan) because of slander. He once wrote the poem Sick Cicada (Chronology of Tang Poetry). In the fifth year of Kaicheng (840), he moved to Zhou Pu to join the army. Five cases of Huichang died in Zhou Pu on July 28th (August 27th) in 843. Jia Dao's poetry formed a school in the late Tang Dynasty, which had great influence. In the Tang Dynasty, Zhang Wei's "Poet's Picture of Subject and Object" was listed as one of the seven people who entered the church as "pure and elegant". In Qing Dynasty, Huaiming Li called him a "lonely man" in the Poet's Subject and Object Map of the Middle and Late Tang Dynasty, and listed many disciples as "entering the room" and "visiting the door". In the late Tang Dynasty, Dong Li, Sun Sheng and others in the Five Dynasties respected Jia Dao very much, and even burned incense to worship his portraits and poems, which was like a miracle (Biography of Tang People, Reading Records of County Zhai). Jia Dao's Collection of the Yangtze River 10, with four series widely used, was photocopied and translated in Song Dynasty. The New Collection of the Yangtze River is based on Jia's poems collected in The Complete Poems of the Tang Dynasty, and other books and related anthologies, anthologies and appendices, such as Chronicle of Jia Dao, Examination of Jia Dao's Friends, and Jia Dao's Poetry Review, are relatively complete.
