As the saying goes, “A hero is known in the time of misfortune （不幸）". Zhong Nanshan is a hero like this. He is a doctor in Guangdong. In 2003, SARS broke out （爆发）in Guangdong. People had a bad cough and got a high fever, lots of people died from the disease （疾病）. Zhong helped a lot of sick people there.
In early 2020, a disease called Novel Coronavirus Pneumonia （新型冠状病毒肺炎） hit Wulian. Zhong Nanshan, 84-year-old, led his team to Wuhan to fight the disease. Zhong's team did their best to help the sick people. He asked 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. When he was 67, he could still play basketball. Now at the age of 84, Zhong still helps sick people in the hospital and teaches young doctors. "I am just a doctor?" Zhong says. But we think he is a hero and a fighter.
Alipay and WeChat Pay are popular everywhere, even in the small shop in China. They're the future ways to pay bills （付账）.
Firstly, it saves people's time to pay bills. People don't need to go outside with cash （现金）. They do not need to count the money or check the bills. Just scan （扫描） the smartphone and the bill will be paid by Alipay or WeChat Pay. It is so easy to pay.
Secondly, people don't have to worry about getting fake cash （假币）. Many years ago, people were easy to get fake cash as they received the change. But now, we use cash less, and people won't get fake cash without paper money. Our life will be much convenient.
