There are plenty of Chinese people who have seen the west and become very critical of the Communist party in China. Up until now, China was viewed as a land of opportunity with vast wealth and riches to be made. In more recent years, that idealistic view has withered away due to the west becoming more aware of some of the values the CCP hold and how they don't align with pretty much the rest of the world.
