In the past, some people were very secretive about freedom, always thinking it was a sensitive word; there were also misunderstandings of one kind or another about freedom.

In fact, the idea of ??freedom is Marx’s basic idea, and this idea is concentrated in Marx’s thought of the “union of free men”. Marx and Engels said in the Communist Manifesto (hereinafter referred to as the "Manifesto"): "What will replace the old bourgeois society where classes and class antagonisms exist will be a union in which everyone The free development of all people is the condition for the free development of all people." However, looking closely at the history of more than 150 years since the birth of the "Manifesto", including the history of the development of socialism, I think there are many ways to understand and apply this famous saying. Something worth rethinking
