In 1711, Chuzang Lozang-tenpay-gyeltsen built a new Tantric College, Ngagpa Dratsang. In 1723, the Qing armies severely damaged the four great monasteries of the Qinghai region – Kumbum, Gonlung, Serkog and Chuzang and many monks fled. Soon afterwards, the Qing commander asked the 21st Throne Holder to convert the new Ngagpa Dratsang into a Medical College, and this was done. With the appointment of several famous doctors, the Medical College, Menpa Dratsang Sorig-dargyey-zhenpen-norbuling was opened in 1725. It became a separate college during the time of the 22nd Throne Holder. The doctors who are graduated receive the Menrampa degree.
