communism made the rich equal with the poor.when chairman Mao was in charge there was famine in China.the famine was there because there were a few rich people becoming richer and everyone else was poor getting poorer.so in order to change this he took from the rich and gave to the poor like robin hood but we labeled him as evil communist. When he established equal rights or communism the famine decreased a lot. But a lot of people didn't want to be communist's so in order to change that chairman Mao said that it was illegal to have anything that could be used as a type of currency or money he called it the old way of thinking.Communism won't work if there is money so he stopped money and made food stamps instead this made a lot of ruckus but it would eliminate obesity and chairman Mao liked the idea.So he made another law that made it so that when you got a job you would be moved next to that job of course this would make a lot of ruckus because there were those who wanted to live in the country but work in the city but over all it would limit travel so less cars and less pollution. so the answer to your question how did communism change CHINA there are many answers.
