Source of inspiration:
"When Zhang Tianshi was in Gui'an, he caught a monster. The crime was not worthy of death, and the merits and demerits were equal to each other, so he sealed it up. The monster begged, and Zhang Tianshi said, 'I will let you out the next time you pass by here.' From then on, the successor Zhang Tianshi will never pass through Gui'an County."... The Tianshi was also cunning.
