The practice of ancestor worship is relatively straightforward....and they have idols and relics of the departed too.... Nearly every house, office, and business in Vietnam has a small altar which is used to commune with ancestors.... Incense sticks are burned frequently. Offerings are made – fruit, sweets, and gifts.... The latter items are paper replicas of dollar notes (‘ghost money’), motorbikes, cars, houses and so on. After worship, the paper gifts are burnt so that the spirits of the gifts can ascend to heaven .for the ancestors to use.
