The people of Rupchu venerate Pullun Ripka Chen. Apart from creating men and women, he is also credited with making the mountains, the plants, their sheep, goats, horses and yaks. They have a carefully worked out system of pasture allocation that prevents overgrazing of their land. Sheep, goats and yaks are branded and each family will have their own mark to distinguish their livestock. The animals are marked either by cutting the ear or else strands of coloured wool or cloth are hung through a hole in their ear.
Sheep wool is the primary material used for weaving but yak and goat hair are also used.
Women first learn to weave around the age of fifteen or sixteen from their mothers and grandmothers. The training begins from weaving the woollen cloth or nambu followed with making blankets or suktul and small carpets or sukden . At first, the young girls find it tiresome to weave. Gradually, they realise the importance of weaving clothes for the entire family. Once the girls become competent, it is common for women to leave the family's weaving on their young daughters.
