Last year, I join a volunteer club to help those people in need. The first activity I participated was to hold a charity sale to collect the money and donations, and then take it to a primary school into deep mountains. The activity was successfully as most of the students supported this charity, donated the money and study materials with kindness. At the weekends, we took the donations to the primary school, which we saw the smiles on children faces, and their poor study circumstances. It was the experiences what made me feel the responsibility to make some differences to their life.

In that little note, I affirmed his talent as a writer and I encouraged him to be responsible for the gift.
