The most powerful weapon against Covid-19
Mum, when you read this message, I have been on the front line against the Covid-19 pandemic. I am terribly sorry because I did not dare to call you in advance. I feared that you would get so worried about me and not be able to sleep. I remember in the past when I only had a slight fever, you stayed up all night sitting by me.
