On Children's Day last year, our city held an interested activity, in which children and their parents play the rich and the poor. In the dinner, the rich could have more delicious food, but the poor could only have breads with porridge(粥). Parents both hoped to have the dinner for the poor with the children. They hoped that their children could be taught the lesson from the dinner. Now many people on earth don't have enough food and clothes. Every day only one half the world could enjoy enough food. The activity was held make the families understand the differences from the poor and the rich and also make the parents know that too much material life won't always do good to the children.
