Jiang Xiaofeng, an ordinary social worker, suddenly discovered one day that he could see ghosts, and inexplicably inherited a "Yin Yang Book" - this thing is not a genealogy, but a "to-do list for the underworld" that records the obsessions of ghosts. From then on, he was forced to become a "yin and yang intermediary", specializing in helping ghosts fulfill their wishes and solving various supernatural incidents.
