They worship spirits, including benevolent and malevolent ones, and believe in the existence of ghosts.

The Idu Mishmi tribe's shaman is called an Igu, and they perform rituals and dances to ensure the safety and health of their families and households.

The Igu wears a coat, loin cloth, and an apron-like garment, and uses musical instruments while dancing, chanting, and singing.

In China, Idu Mishmi is spoken in Xiba village 西巴村, which has just over 40 residents and is located at the foot of Xikong Mountain 习孔山.

They are officially classified by the Chinese government as ethnic Lhoba people.
