Gao Xianzhi
In 734 the Tibetans married their princess Dronmalön ("‘Dron ma lon") to the Türgesh Qaghan. The Chinese allied with the Caliphate to attack the Türgesh. After victory and peace with the Türgesh, the Chinese attacked the Tibetan army. The Tibetans suffered several defeats in the east, despite strength in the west. The Türgesh empire collapsed from internal strife. In 737, the Tibetans launched an attack against the king of Bru-za (Gilgit), who asked for Chinese help, but was ultimately forced to pay homage to Tibet. In 747, the hold of Tibet was loosened by the campaign of general Gao Xianzhi, who tried to re-open the direct communications between Central Asia and Kashmir.
