which religion gives order to the social structure of vietnam
Religion in Vietnam Although according to a 1999 census most Vietnamese list themselves as having no religious affiliation,[6] religion, as defined by shared beliefs and practices, remains an integral part of Vietnamese life,[7] dictating the social behaviours and spiritual practices of Vietnamese individuals in Vietnam and abroad. The triple religion (Vietnamese: tam giáo), referring to the syncretic combination of Mahayana Buddhism, Confucianism, and Taoism, and Vietnamese folk religion (often combined too with them), remain a strong influence on the beliefs and practices of the Vietnamese, even if the levels of formal membership in these religious communities may not reflect that influence. One of the most notable and universal spiritual practices common to Vietnamese is ancestor veneration, a practice shared with Chinese and most other Asian cultures. Practically all Vietnamese, regardless of formal religious affiliation, have an altar in their home or business where prayers are offered to their ancestors. These offerings and practices are done frequently during important traditional or religious celebrations (e.g., death anniversaries), the starting of a new business, or even when a family member needs guidance or counsel. Belief in ghosts and spirits is common; it is commonly believed that failing to perform the proper rituals for one's ancestors will cause them to become hungry ghosts (Vietnamese: ma đói).[nb 1]
