In this chapter, we learn that the song was written by a young man named Cai Ming. Cai Ming is the son of Cai Ming's first wife, who died when Cai Ming was a young child. He is now married to Cai Ling's sister, who is also a young woman, and Cai Ming has taken Cai Ming under his wing. He tells Cai Ming that Cai Ming owes him a lot of money and that he should pay it immediately. He also warns Cai Ming not to tell Cai Ming about his father's death, because if Cai Ming dies, Cai Ming will be responsible for his son's debts.
