宋江
One night, she discovers Chao Gai's letter to Song Jiang, and threatens to report Song Jiang to the magistrate for associating with the outlaws unless he agrees to three conditions: 1) allow her to marry Zhang Wenyuan; 2) let her keep all the clothes, ornaments, property, etc., he has given her; and 3) give her the gold bars from Chao Gai. Song Jiang agrees but cannot fulfil the third condition because he only accepted one of the one hundred gold bars mentioned in Chao Gai's letter. Yan Poxi refuses to believe him and continues to threaten to report him. Song Jiang eventually loses patience and stabs her to death in a fit of anger. He then burns the letter and escapes from Yuncheng County.
