What's the name of the song that Tik Tok made COVID-19 have a fever?

Rainstorm and rainbow, sonorous roses. The song Rainstorm Rainbow, sonorous Rose is intended to show a rainbow after a heavy wind and rain. After the storm, the roses are still strong and upward. The arrival of COVID-19 caught us off guard. Through the efforts of United front-line workers, we blossomed sonorous roses after the epidemic.
