What is communism?
It is a system of social organization in which all economic and social activity is controlled by a totalitarian state dominated by a single and self-perpetuating political party.
Mao Zedong was a poor person who became the main leader of the communism party in China around 1949. His goal was to achieve the liberation of the proletariat class, although he tried to achieve it with totalitarian strategy.
That situation changed when Deng Xiaoping took the power. He thought in a different way as Mao did. Deng's goal was to have a free market so that the economy could increase and get better.
After Deng, the next president was Jian Zemin, who allowed private entrepreneurs to exist in China.
