As the economy develops constantly, our lives have a great changed. But we can't ignore that some people are still poor and can't hold on their families. I think it is necessary to help those underprivileged people.
Maybe some people will consider the money, but contributing is only as a means of helping them. We also have many other ways to help them. It is important for us to do some things which we can do, which can spread to all the society. When all people are unconcious to do these things, our society become really perfect.
Helping others is simple, such as giving some books or clothes. If you have a kind heart, you will become a candle to light this world.
