1. There are many people in society who need our help. If each of us only donates one yuan to charity fund, then one yuan of 200 people can help a child who dropped out of school to return to school. We donate clothes we don't wear and books we don't use to help children who are still worried about food and clothing and can't read. 2. While helping others, such activities are also helping themselves, improving their moral quality, strengthening communication between people through public welfare funds, and making us more United and more accepted and recognized by society.
