A nine-year-old boy of the Yang family in the country of Liang was very clever. One day, Kung Junping paid a visit to Yang, but the latter was not home. So the boy came out as the host and provided a plate of fruits, including plums, to Kung. Kung pointed at the plums and said, "These are the fruit of your family." The Yang boy responded instantly, "I have never heard that the peacock is a bird of your family, Sir."
