The Yin-Yang Coffin: Subduing a Hundred Ghosts

My grandfather's name is Yin Shiba. Mine is Yin Shiliu. Our surname, Yin, has nothing to do with our family name. It comes from our profession. My grandfather is an old-fashioned coffin maker. Because I was born with an excess of yin energy, I was raised in a coffin from the time I was little. On Ghost Festival, we closed up shop early, but a customer suddenly showed up. My grandfather tensed, as if facing a great enemy. “It's Ghost Festival today. I don't make coffins for people.” The man gave a sinister laugh. “Who said I was human?”
