How to tell children the traditional virtues of chopsticks

When eating, chopsticks are placed on the table. Unless the elders move chopsticks, the children can't move first, which is a respect for the elders. When picking vegetables, don't put them all over a plate, don't push the bowl with chopsticks, don't knock on the plate with chopsticks when eating, don't put chopsticks on the bowl after eating, don't insert chopsticks into rice or rice, and put two chopsticks side by side on the table.
