Lyrics excerpt: Knock on the disc in your hand, the ditty is very easy to sing, and the song is endless. Husband and boss listened heartily, and the moon curved on the tall building, which was originally built by the poor. When the north wind blows in the cold winter, the rich laugh and the poor worry.
