Confucianism and Taoism have been primarily practiced in China.

Explanation:

The predominant religions in China are Buddhism, Taoism, Confucianism and traditional Chinese religion, which, in many cases, are practiced together and a form of religious syncretism. However, a large majority of the population does not identify with any religion, being agnostics, atheists or just spiritual people not attached to any religion.

Confucianism is the set of moral and religious doctrines preached by the disciples and followers of Confucius after his death. Confucianism has exerted a great influence on China, Korea, Vietnam and Japan. It was the official religion of China until the seventh century.

Taoism is a philosophical system and religion that originated in China in the sixth century BC; is characterized by believing that there is an absolute solidarity between man and nature, since both agree perfectly and have a common substrate.
