Ba Chua Xu Festival is one of the biggest religious events in South Viet Nam, attracting nearly two million pilgrims yearly.

In the southern culture, Ba Chua Xu represents an image of a protector of the Vietnamese border and a tutelary of prosperity and health, and has many names, including Chua Xu Thanh Mau (Holly Mother of the Realm).

In addition to communal houses across villages, the Lady of the Realm is worshipped in small shrines and even in Buddhist temples, usually represented by glass paintings, and wooden or cement statues. 

The Ba Chua Xu Festival in Chau Doc's Sam Mountain is held from the 23rd to the 27th day of the fourth lunar month, with the main rituals on the 25th.
