    I watched my Dad close the door. It was a really cold night in dead silence and I was all alone at home. My parents left because they had been running fever for several days and they were showing other symptoms of COVID-19. It was the 9th day of Wuhan lockdown starting on January 23.

The virus we now know as COVID-19 is somehow fearsome partly because it does not discriminate (区别对待) in choosing who it infects. But that is only partly true. All the evidence suggest that it can be merciless to older people, so I was wondering whether my parents would make it and whether we would ever take family photos, which my parents and I had talked about during the Spring Festival holiday..

On their second day away my parents called and asked me how I was. We talked using FaceTime, and the moment I saw mom lying there with an oxygen mask and my dad could not talk without breathing heavily, I realized that I had to live on my own.

But two weeks later, I came across a fever and had to go into quarantine (隔离) and be put under medical observations for 14 days. Fortunately, my illness turned out to be due to a bacterial infections but not COVID-19.

Everything there was hectic, there seemed to be a shortage of medical staff and materials were in short supply. Even though the doctors and nurses were covered from head to toe, I could see how tired they were when I looked into their bloodshot eyes.

They would work a whole day preparing for new patients and seemed incredibly apologetic for not having everything that was needed. Most of the patients were really understanding, but of course there were those who were not, and complained loudly, but all the doctors and nurses tried their best to deal with it in a calming way. And they are all from other cities like Shanghai and Guangzhou, and some of them are just three or four years older than me.

When the quarantine was over, every patient effusively thanked the workers for what they had done, but the answer they received was exactly the same: “That’s what we’re here for.”
