Song Jiang was arrested in Jiangzhou, and Wu Yong offered a dedication to Dai Zhong to invite the scholar Xiao Rang and the stone-engraved jade arm craftsman Jin Dajian to Liangshan to forge Cai Jing documents to save Song Jiang. Jin Dajian went to Liangshan from then on. In charge of Liangshan writing and dispatching troops, he is a civilian general in Liangshan. Ranked sixty-sixth in Liangshan. When Song Jiang conquered Fang La, Jin Dajian did not go to war and stayed in Beijing. Jin Dajian doesn't like to talk, and Jin Dajian knows too much. Jin Dajian lives in the shadow of Wu Yong. Xiao Jean and Jin Dajian participated in the astronomical mission of Shijie Loyalty Hall planned by Wu Li. Wu Yong's trick made Liangshan's right integration movement completely enter the predetermined track, and finally became an indisputable foregone conclusion. Except the planners Song Jiang and Wu Yong and the used tools Xiao and Jin Dajian, who would have thought that the stone that Xiao and Jin secretly built all night was actually carrying a notorious conspiracy? Jin Dajian

Jin Dajian is a Liangshan hero who didn't take part in the conscription in Fang La, which may have saved him from death, but in the end, Jin Dajian became the object of his previous imitation-a door official under Cai Jing, and Jin Dajian will continue to live in the shadow of Cai Jing, which is another joke played by fate and Jin Dajian. This is found.
