Love makes the world warm. Cheng Dongdong really knows what it means. Cheng, 20, comes from Anhui. He lost the ability to walk when he was a little boy. So he had to go to school in a wheelchair （轮椅） .Luckily, his classmates would push him around the school. From primary school to high school, they were there to help Cheng out. They kept an eye on him and gave him hand on school days.
In 2010, when he was in primary school, eight students in Cheng's class formed a group to take care of him. This little bit of love cheered Cheng up and helped him become happy. In 2014. Cheng went to middle school. Six students in his class set up new group to make the" relay（接力赛） of love" go on.in2017, another six students took the "baton"（接力棒） and continued to help and care for Cheng in high school.
This July, Cheng finished high school. For him the last ten years were full of love and hope. He thanked his classmates a lot.
