 Nhà thờ họ are family shrines of northern and middle Vietnam, equivalent to the Chinese ancestral shrines.Another categorisation proposed by observing the vernacular usage is that miếu are temples enshrining nature gods (earth gods, water gods, fire gods), or family chapels (gia miếu); đình are shrines of tutelary deities of a place; and đền are shrines of deified heroes, kings, and other virtuous historical persons.Actually, other terms, often of local usage, exist.
