It was said that he could help people get rid of evil forces. In some stories, Zhang Zhen was described as a handsome man who had an extraordinary ability to communicate with ghosts. There were also stories about Zhang Zhen and his friends who fought against the evil forces and finally succeeded in getting rid of the ghost's control. However, the authenticity and scientific nature of these stories are controversial because the question of whether ghosts really exist is also worth exploring.
