Li Yue and Zhang Hua went to︿nursing home and did some voluntary work on May Day. At their arrival, they were warm welcomed. They presented the elderly people with flowers and fruits. Then, they started working at once, cleaning the windows and swept the floor. Everything done, they sit in the yard chatting with the elderly. When it was time for the volunteer to leave, the elderly thanked them for their kindness. Li Yue and Zhang Hua were very happy because of what they did bring joy to others. It also enriched our own experience. They made a promise which they would come again to see the elderly whenever they were free.
