Dear Editor,
I am high school student. Here I would like to express my sincerely gratitude through your newspaper to all the medical workers for your devotion and sacrifice in this battle against the Covid-19 virus. It is they who, despite of the lack of equipment and the potential of infection, desperately rescue those infecting and striving for life. It is also they who have shed new light on the virus to build up our confidence to defeat it. It is they who deserves all the admiration and love! I can ever express our thankfulness too much for their selfless contributions. As the virus is very hard to clear, I'm convinced that China will win the battle and make a quick recover. Finally, I hoped all of them will stay healthy and happy.
Yours sincerely,
Li Hua
