There are jokes about children.

A classmate asked the teacher the day before Children's Day: "Teacher, do you have any homework today?" "No." The teacher said. The classmate asked again, "Will you have a holiday tomorrow?" "Let go," said the teacher. That classmate jumped with joy. "Why are you so happy?" The teacher asked. "Because you said that there will be no homework tomorrow, and there will be a holiday." This classmate said. "You have no homework, but your parents have homework." The teacher said. "What homework?" The classmate asked. "Let your parents sign." The teacher said. "Then let's do our homework." This classmate said.
