An Old-School Historical Romance About a Female Underworld Officer Who Hunts Ghosts in the Human World and Sends Them Off to Reincarnate 女主是阴差，在人间抓鬼送鬼投胎的古早古言小说

Help me find a book! The female lead works as a ghost officer in the underworld and gets along well with Ox-Head and Horse-Face. She often goes to the human world to catch ghosts and send them back to be reincarnated. I can't remember the male lead's identity. It's a very old historical romance novel that I read as a child.
