By 1931 the Tibetan government (Ganden Phodrang) was able to dismantle the Powo kingdom and the region came under the direct rule of the central Tibetan Government in Lhasa. Ganden Phodrang had its governor stationed in Medog Dzong, who looked after the territory and established communications between Lhasa and Pemako. Compulsory taxes in cash or goods were to be paid to Lhasa. The region of Pemako was divided among different monasteries and different aristocratic families. Some regions of Pemako pay tax to the Sera Monastery in the form of grains, chillis, bamboo poles for prayer flags (Dharchen), products made of cane, medicinal herbs such as yertsa-goonbu, mushroom, and animal skin.
