My name is Zhang Wei, and I live in the countryside. My next-door neighbor, whose surname is Gao, knows how to deal with all sorts of uncanny matters. The villagers respectfully call him Mr. Gao. Since our homes are separated by only one wall, I often go over to his place to hang out. He’s especially kind to me and always prepares plenty of good food whenever I visit. Sometimes people come to him for help with strange affairs, too, so I’ve heard and seen all kinds of unbelievable things.
