Essays / Need Help on Essay Topic ( Chinese Revolution / Mao Zedong) [5]

I am struggling with an essay topic for my history class. The subject area is the Chinese Revolution. It is a standard 5 paragraph persuasive essay. The exact prompt is "Looking from the Communist Revolution in 1949 to Mao's death in 1976, how successful was Mao Zedong and the Communist Party, in moving China toward a more equal, more prosperous and more free society?". What can y'all suggest I say, more specifically what can you recommend to use a evidence / argument. I am looking to outline my essay and need help finding some arguments that i can use.
