I was overwhelmingly touched by the short Chinese video entitled “wordless.” It depicted the mobilization of medical personnel from all parts of China to WuHan, like going to a war zone to combat the COVID-19. Among them were volunteer experts of respiration, influenza, epidemiology. Streaming of trucks transported thousands of brave medical professionals to the gravely silent city, WuHan. A mother tucked packages of snack into her son’s backpack and hug him with tears for goodbye. Without doubt, her only prayer was for his safe return.
