To show our love for poor kids lived in mountainous areas, our school hold a special activity last week in our school square. Its purpose was to making sure those poor kids have a warm winter. All the teachers and students in our school took an actively part in this activity. We gave away 478 pieces of clothes and 256 pairs of shoe altogether. After be sorted, they will be sent to those in the need. I believe what they did will make a great difference to those poor kids. Although we all learn to care for others, the world will be more comfortable to live.
