As the epidemic became serious and unable to go out, Liu Ying was originally the veteran of the Jinfeng Chorus. In order to inspire everyone to get rid of the dull atmosphere, she launched the "Happy Sing Everyone" platform, and everyone sang happy emotions together. Jinfeng Director Wang Tongchun will continue to organize "Happy Sing Together" in early January 2021. His intoxicating and beautiful singing voice, and his passion for teaching everyone to sing, really add to the joy of life. Everyone sang once a week, and everyone sang so much that they almost forgot that it was during the epidemic.
