Dai Zong
When Song Jiang is exiled to Jiangzhou as a mitigated sentence for killing his mistress Yan Poxi, he passes by Liangshan and meets Wu Yong, who writes a letter for him to take to Dai Zong. The letter requests Dai to treat Song well. In Jiangzhou, Dai initially wants Song Jiang to bribe him in exchange for lenient treatment. After reading Wu Yong's letter, Dai Zong apologises and makes all efforts to ensure Song has a comfortable life in prison. In fact Song can go in and out of the prison camp at will. He also comes to know and develop a strong bond with Dai Zong's subordinate, the jailer Li Kui.
