1. Deep reflection on social reality: The late Tang Dynasty in which Meng Jiao lived was an era of political corruption and social unrest. In his poems, he profoundly exposed the dark side of society and the sufferings of the people at that time, as if he were trapped in these realities and could only talk and tell through poems.
2. Bitterness and creative attitude: Meng Jiao worked very hard in poetry, focused on refining words and casting sentences, and devoted great enthusiasm and energy to poetry creation. He seems to be bound by poetry creation and immersed in it like a prisoner.
3. Personal experience and emotional projection: Meng Jiao failed many times in the imperial examination in his early years, and was admitted to Jinshi after middle age, and his incompetence was deeply reflected in his poems. His poems often express the difficulties and disappointments in life, reflecting his strong feelings about the realistic predicament.
4. Yuan Haowen's evaluation influence: The word "poetry prisoner" first appeared in Yuan Haowen's works. He used it to describe Meng Jiao's obsession with poetry and the depression and struggle reflected in his works, and thought that Meng Jiao seemed to be a poet imprisoned by poetry.
