From then on, it is said that this is the fruit of your family, but the answer is that I have never heard that peacock is a master of poultry. What does this mean?

This sentence comes from the son of Yang in Shi Shuo Xin Yu. The original sentence was "Confucius pointed out to my son that this is the fruit of your family, and my son replied, I have never heard that peacock is a master of poultry." Junping Kong pointed to Yangmei and showed it to the child, saying, "This is your fruit." The child immediately replied, "I haven't heard that peacock is your bird." When Junping Kong saw Yangmei and thought of the child's surname, he deliberately teased the child: "This is the fruit of your family." It means that your surname is Yang and your name is Yangmei. You are family! "This handy joke is humorous and interesting. The child replied, "I haven't heard that peacock is your bird." He didn't directly say "Peacock is a master of poultry" stiffly, but took a negative way, saying "Peacock is not a master of poultry" and answered tactfully, which not only showed due courtesy, but also expressed the meaning of "Since Peacock is not your bird, Myrica rubra is my fruit", leaving Junping Kong speechless.
