The story happened in a temple situated in the countryside in Tainan county. It was the most important moment of the night, when the spiritual medium was to select the official keeper of the incense burner for the next year. (Every year the keeper coordinates the temple's religious ceremonies.)
故事發生在台南縣鄉下的一座寺廟，晚上正是最重要的時間，因為乩童要選出下一年的爐主（每年統籌該村廟祭祀大事的負責人）。
