This year had a special sense of summer, I went to xi ‘an to see the mentally disabled children, the activity center place is not big, but it contains a lot of people, their different ages, different reasons together, studying here, living here, no parents accompany .Some children life can’t provide for themselves, most adult assistance. We sent a lot of articles daily use for them .I hope that their life can be better. We sing and dance happily together, they are versatile, confident performance got a burst of applause. Although fate let their body is not complete, but their smile, strong, optimistic deeply touched me. Let me feel a little heartache .I hope more people can have time to look them .I also hope that more people can help them. Mentally retarded son of the director of the center for children is one of them, although the intellect, but he is very good at playing the piano, he hopes that he can open a piano concert .I hope who has the resources of good intention can help him to achieve his wishes!
