MUI blames BUT for claiming to be LUNG, her grandson. BUT is nervous. But when he learns from her maid, SIU MEI, that she is suffering from dementia, he decides to get away with it by saying that MUI has mistaken YAN for her grandson. YAN plays a sad song. BUT encourages him to forget about the past. He also takes the opportunity to invite BUT to take up the post of music instructor. The red mark on YAN’s face has turned into little spots after applying MUI’s ointment. He turns to SHAN for help. FONG, one of the dancers of Cheung Lai Yuen, has never been invited to perform because of her body odor. She puts a red hot coal under her armpit in order to solve the problem. YIN and BUT have a good time playing the horsehead fiddle together. BUT’s boil breaks out. He asks SHAN to go to the mountain to gather medicinal herbs with him. WAN recommends LONG to Cheung Lai Yuen. BUT agrees to hire him as a classroom assistant.
