因为最近的新冠肺炎对人们的生活造成了巨大的影响，人们针对它做了很多的措施。联系到过去一个世纪发生的几次重大流行病，我认为这些世界各地第一线的英雄们的抗疫智慧应该被记录下来，也可以留给后人参考。

 

      The recent Coronavirus disease has caused a huge impact on people's lives, and the public has taken a lot of measures to fight against it. Relating to several major epidemics that have occurred in the past century, I think the counter-epidemic wisdom of these first-line heroes from all over the world should be recorded and imparted for future reference.
