戴宗
One day Song Jiang, feeling miserable over his misfortunes, writes a poem on the wall of a restaurant after getting drunk. The seditious poem is discovered by a petty official Huang Wenbing, who reports it to Cai Jiu, the prefect of Jiangzhou. Cai orders Dai Zong to take Song to him. Dai tells Song to pretend to be insane to suggest the poem is the scribble of a mad man. However, Huang Wenbing sees through the pretence and suggests giving Song a sound beating to make him "sober". Song eventually admits that his mind is sound.
