"I feel very reluctant to give up. When they leave on weekends, I will come to see them off." It is hard to teach, but the smile of the children makes us full of motivation for the volunteers of the school of mechanical manufacturing of Jinan Vocational College. This summer is also a profound memory of their students' career. Many volunteers were the first to take part in the teaching activities, although the conditions were very difficult, but the smiles and feelings of the support were enough to overcome the difficulties and full of vitality.
