Last night, when watched the annual Ten People Who Moved Chinese the Most in the CCTV, I learn some deeds of helping the poor children. It makes me have a firm belief what there are still many kind but generous people around us. It is common believed that many children in the remote mountainous areas of our country have few opportunity to receive education for various reasons. Now that we have the chance receive a good education, we should treasure them. As far as I'm concerned about, if we are friendly and help each other, we can live harmonious and happy life together.
