What does it mean for a peacock to be a master of poultry?

A new word from the world. My son Liang is nine years old and very clever. Junping Kong thought of his father, but when his father was away, he shouted. In order to set fruit, the fruit has bayberry. Confucius pointed out to his son and said, "This is the fruit of your family." The son replied, "I haven't heard that peacock is a master of poultry."

Translation-

In the state of Liang, there is a family named Yang. There is a nine-year-old son at home who is very clever. On one occasion, Junping Kong came to visit his father. Just as his father was not at home, Junping Kong called the child out. The child brought Junping Kong fruits, including bayberry. Junping Kong pointed to Yangmei and showed it to the child, saying, "This is the fruit of your family." The child replied, "I have never heard that the peacock is your bird." It means "here". . The meaning of "look"

Confucius pointed out to his son and said, "This is the fruit of your family." The son replied, "I haven't heard that peacock is a master of poultry."

This is the key part of the story. 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." "Poultry" in the sentence is different from "Poultry" now, and "home" and "Poultry" here express their meanings independently.
