Dr. Su replies that he thinks he's an "evil portent" . He's the one who caused his father's death, and he can do nothing to stop it. He says that if his master were here, he'd be able to enjoy the family's love and joy. He asks where his master is, and the doctor tells him to look at the waters of Luo, with its "broad and deep waters." The doctor says that his pet name is "very special" , which means that his mom named him after a poem in which the word "sing" is used.
