Buddhism first appeared in China in the first century CE, and by the fourth century had become one of the major religions of the country, along with Daoism and Confucianism. Essentially all Chinese Buddhism is Mahayana; Vajrayana teachings flourished for a brief period in the eighth century, but suffered repression and mostly disappeared as an organized school of practice, except in the southwest. Chan (Zen) Buddhism is a unique Chinese tradition, known for its teachings on sudden enlightenment, some of which parallel teachings of Dzogchen (the Great Perfection) practiced in Tibetan regions. Other Chinese Buddhists follow Pure Land teachings, hoping to be reborn in the western paradise of Amitabha.
