The Luru Festival in Rebgong is related to Bön, the spiritual tradition predating Buddhism. White incense and red incense are offered to the local guardian deity; white incense is offered during the first female dance, and red incense is offered during the second dance. All the men from the upper and lower village hold self-prepared incense and line up at the altar in order to offer. Burnt offerings pile up like a mountain, wine offerings build up like and ocean, paper prayer flags cover the sky, and shouts of "Kuso" ring through heaven and earth. Then, the mouth piercing ritual occurs where the youth show the spirit of their faith.
