Last Saturday, our class paid the visit to the Welfare Centre for children in our city. On our arrival, we donated some gift to the kids, which made them very pleased. Then we did what we could help them. Some swept and tidied their rooms. Some play games with them. And others told interesting stories to them. The day passed quickly after we knew it.
Honestly speaking, though tired, they were much happier than ever that day. The reason is that when we help with others, we also get something more importantly. Therefore, show your love and care, or our society will be more beauty and more harmonious.
