Xu Hanchi, 13:

I went to a square(广场)in a local university with my classmates to do cleaning. We swept off the fallen leaves and picked up rubbish. When we finished, the ground was very clean. Though no one came up to praise us, we still felt very happy. We learned that doing good things itself could make us happy.

Zhu Lingyue, 14:

My group cleaned the teachers’ office that day. When we got there, we were surprised that the office was not as clean as we expected. How could teachers work in such an untidy(不整洁的) place? We started cleaning quickly. Teachers work really hard and may not have the time to clean their offices. It’s great that we can do something to help make them less tired.

Tom Rui, 14:

We helped clean the yard in the front of a hospital, but some patients(病人) there left us a very bad impression(印象). They were very impolite and shouted at nurses and doctors.
