Lha-bzang Khan
Amdo, meanwhile, became home to the Khoshuts. The descendants of Güshi Khan continued to rule as Dharma kings (chogyals) of Tibet, although they were eclipsed by the Dalai Lama and his regent for long periods. In 1717, however, the Dzungars, led by Tsewang Rabtan's brother Tsering Dondup, invaded Tibet. The invaders defeated and killed Lha-bzang Khan (the last khan of the Khoshut Khanate), a great-grandson of Güshi Khan and the fifth Dharma king of Tibet. The Dzungars deposed a pretender to the position of the Dalai Lama who had previously been promoted by Lha-bzang Khan. The 5th Dalai Lama had encouraged Mongolian lamas to prevent any non-dGe-lugs-pa teaching among the Mongols. The Dzungars soon began to loot Lhasa, thus losing initial Tibetan goodwill towards them. Many Nyingmapa and Bonpos were executed and Tibetans visiting Dzungar officials were forced to stick their tongues out so the Dzungars could tell if the person recited constant mantras (which was said to make the tongue black or brown). This allowed them to pick the Nyingmapa and Bonpos, who recited many magic-mantras. This habit of sticking one's tongue out as a mark of respect on greeting someone has remained a Tibetan custom until recent times.
