Where are the rich and the poor laughing?

Both the rich and the poor laugh as the moon bends over Kyushu. The Moon Bends in Kyushu is a local folk song that has spread in Jiangsu Province since the Southern Song Dynasty. The excerpts of folk songs are: "Six animals flourish, and the rich and the poor laugh". So the rich and the poor laughed at the bright moon and bowed to Kyushu.
