Religions in Vietnam are quite diverse, including Buddhism (both Mahayana and Theravada and some groups are based on Buddhist philosophy but modified to adapt to culture); Christianity (including Roman Catholicism and Protestantism); endogenous religion such as Cao Dai; and several other religions (Islam and Hinduism). Until now, indigenous folk beliefs still have a certain influence in Vietnam. Ancient Vietnam had forms of religious practice towards natural objects. Religion in Vietnam has a relationship with Chinese and Indian civilizations, but Vietnamese people also incorporate traditional elements of their national ethics into it to form a religion with its own identity.
