Combo photo shows classmate carrying Cheng Dongdong in Qiucun primary school (L, taken on March 3, 2012), in Guangde middle school (C, taken on May 28, 2020) and in Chaohu University (R, taken on Oct. 19, 2020) in east China's Anhui Province. Born in Qiucun Town of Guangde City in 2001, Cheng Dongdong was diagnosed with Amyotrophic Lateral Sclerosis (ALS) in 2008. From primary school to high school, Cheng had been receiving help from his classmates. In September 2020, Cheng began his university life and got supports from his new classmates as before. Looking back at 2020, there are always some warm pictures and touching moments: the dedication on the front line to fight against the epidemic, the perseverance on the way out of poverty, the courage to shoulder the responsibility on the embankment against the flood, the joy and pride when reaching the summit of Mount Qomolangma... These people and things touch our hearts and give us warmth and strength. (Xinhua)
