Legend has it that in addition to angels and black and white emissaries from hell, there are also extremely spiritual people in the human world who specialize in connecting heaven and earth. They are called "soul-killers" and specialize in treating lonely and resentful ghosts who refuse to obey discipline and refuse to reincarnate. There was an old man in the Chu family in Nanyueling who was good at this job, but he could not find a successor until he met his grandson whom he had not seen for many years.
Old Chu burst into tears, "Finally we found our successor!"
