"In this critical moment of fighting the plague, we hope the song can spread more fire and less stress to the frontline soldiers of this war," a caption accompanying the song on YouTube says.

"That is the team of experts, physicians, health workers and millions of workers who are in the front lines of exposure and daily struggle with the disease."

The song includes lyrics like: "Wash our hands, rub, rub, rub, rub evenly", "Do not touch eyes, nose, mouth", and "limit visits to crowded places".
