Under intense contact with the Tibetans since ancient times, the Pumi were influenced by Tibetan Buddhism, along the older practice of Bön.

The Zanbala religion, also locally known as Dingba, literally means white earth. It is noted that the Pumi around Ninglang still install Zanbala altars in their home, which were worshipped by the older generations.

The Zanbala religion consists of the veneration of three gods and ancestral spirits, in which only the old men preside the rituals and prayers.

Almost all Pumi villages have their own local mountain gods, which are worshipped during festive seasons. On those days, the entire family will give food offerings and pray for the good health and prosperity of the family.

On the 15th day of each month, the minor mountain god is worshipped, and a grand ceremony is held on the 15th day of the 7th lunar month to venerate the Great Mountain God.

In many of the Pumi homes, a cooking fire ring plays an important part of Pumi beliefs. The ring should never be touched by guests. A Guazei, which consists of small stone towers, is located behind the fire rings.

During mealtime, the oldest male will take a spoonful of the food, which will subsequently be placed on every tower. One spoonful will be thrown into the fire, which acts as a symbolic gesture to feed the spirits of their ancestors.
