During the years 882-884 (129-131 AD) the Tibetans moved out from the Yarlung Valley to take the other areas of the Plateau near the Himalayas. The Monpa people, near and similar to the ethnically Tibetan people, allied themselves with the emperor Tisho Lek and together moved out into the areas of the Qiang and Lhoba people. This war was very costly but the Tibetans emerged victorious despite the support that the Sinicans gave to the Lhoba and Qiang people. Guru Lek, son of Tisho, invited the Emperor of Sinica, Yuanhong, to his palace in Sengdroma (Lhasa) and made peace with the nearest major powers, which were Sinica and the Maurya.
