Red Guard song / Who wrote the song? Why do you think the song was written?

I am assuming you’re talking about the Cultral Revolution in China so that is what I will give you information on. The song was about standing up and fighting the bureaucracy that was dominant at that time. It encouraged people to start a revolution against evil and defend Mao Zedong. It was written by Li Jiefu. The song says "red guards, red guards, we want to be the successors to communism. The revolutionary red banner passes on from generation to generation, we want to carry on the glorious tradition. Loving the country, loving the people, loving the collective, loving to work. Connecting with the workers and the peasants, we are chairman mao’s red guards."
