"Outlaws of the Marsh" is a great story, I read it at one go.
This book was written by Shi Naian, mainly about 108 heroes trapped in Liangshan, who wanted to act on behalf of heaven, kill corrupt officials and rob the rich to help the poor. However, the Imperial Court didn't know what they were doing and wanted to kill them.
However, the heroes of Liangshan didn't hurt them, and they discussed with their court about the imperial edict. In the end, the Imperial Court gave Song Jiang poisoned wine and killed him.
So I understand that it is not difficult to gain your trust, as long as you sit down and talk about doing it with practical actions, you can gain your trust. Don't believe you to try.
