Is any part of china not communist?

No, there is no part of mainland China that is not communist. The People's Republic of China is a socialist state with a one-party system, and the Communist Party of China (CPC) is the sole ruling party. Hong Kong and Macau are two special administrative regions of China that have a high degree of autonomy, but they are still under the ultimate authority of the CPC. Taiwan is a self-governing island that is not part of the People's Republic of China, but it is claimed by the CPC as part of its territory.
