In every Phula home, a central room is dedicated to the worship of ancestors. The room contains an altar and a spirit door where the Phula people pray and give regular offerings to the spirits of the dead.
A typical Pa Hng home is only complete with an ancestor altar. The Pa Hng (also called Pa Then) are avid ancestor worshippers, often calling on the spirits of the dead to share in feasts and protect the family from injury and sickness. Pa Hng people feed their ancestors by placing rice and meat on the table for them each meal.
The Mang people group has a population in Vietnam of 3,700 and is one of 23 groups considered to be unengaged and unreached. This means that not only are the Mang less than 2 percent Evangelical Christian, but there are no current efforts to reach the Mang with the gospel. Many Mang will live their whole lives and never have the chance to hear about Jesus unless something changes.
