The narrator is in a brothel, and he hears a noisy noise coming from the upstairs. He goes to investigate, and finds that the brothel is much bigger than he expected. He realizes that the sound is coming from an upstairs room, and wonders how they could create such a magnificent effect with the sound. The narrator's friend, who is standing outside, tells the narrator that the piece that Lady Lingyun just performed was "enchanting and unforgettable." The narrator says that he hopes he hasn't embarrassed himself before everyone here, and the friend asks the young master to have a seat. The young master replies that he doesn't know much about music theory, and that the "uncultured guy" from the brothel ruined the mood. He then plays another piece of music, this time called the "heavenly plume void moon." He says that this piece was written by Emperor tianling and is incomplete, but that he can still play it well enough.
