As the saying goes, "A hero is known in the time of misfortune."
Zhong Nanshan is a hero like this. He is a doctor in Guangdong. He saved many people's lives in 2003. In 2003, SARS (非典) broke out (爆发) in Guangdong. Hundreds of patients even died from the disease. But Zhong was brave enough to fight the disease. Many patients got better. In early 2020, a disease called COVID-19 (新冠肺炎) hit Wuhan. It spread quickly. Thousands of Chinese people were infected (感染). Zhong led his team to Wuhan to fight the illness. Zhong advised people to wear masks, wash hands frequently (频繁地), stay at home and not to go to crowed places.
Zhong likes sports very much. Although he was 84, he could still play basketball. Zhang still treats patients in the hospital and teaches young doctors. He always says "I am just a doctor." But we think he is a hero and a fighter.
