Initially Gomé Gyelpo (mgo smad rgyal po) was one of the eighteen Gyelrong (rgyal rong) kings, and he was granted the title of zhangguansi (长官司) during the Yuan period. In the 1360s Yu Xibo, the brother of Yuan Chengzong Temur, was granted the title “Head of One-Thousand Households” (stong dpon, qianhu 千户), with the rank of assistant regional commander (xie shou 协守) to rule over the land that had been under Gomé Gyelpo. In 1712, Yu Mingqi was granted the title of zhangguansi, and there were altogether 120 households under his rule. The annual grain taxes were fifty-five taels of silver.
