Chen Jie and Ai Xiaoxiang often get pocket money. They feel very happy about it. One day, Ai Xiaoxiang asks, "How should we use this money?"
They decide to save their pocket money in a piggy bank. Every time they get money, they put it into the piggy bank with a smile. They really want to see what the piggy bank looks like when it is full.
After saving for a while, they open the piggy bank and count the money. They take out the coins one by one. They want to know how much money they have.
They decide to donate the pocket money they've saved. They want to help others. Others think it is very good of them to do so.
