On the eve of May Day in 1921, workers at the Changxindian Labor Tutorial School founded by Deng Zhongxia, a member of the Beijing ****productivist group, and others learned to sing the "May Day Commemorative Song". The lyrics of the song were: "Freedom is beautiful, the star of the world, I fight for it with my blood, I sacrifice for it, I want to sweep away the system of power, remember the good day of May 1, the red flag is flying, take the bright road. The red flag is flying, take the bright road, each can do his best, each get what he needs, no matter rich or poor, noble or lowly, the responsibility is only to help each other, may we all work hard to forge ahead." This powerful song was created by the faculty of Changxindian Labor Internship School and the progressive students of Peking University **** together.
