Orlogjav, born in 1950 in Khar Us, retired from the Oirat Mongolian Radio Station in Urumqi after serving more than forty years as a translator, editor, and journalist. Orlogjav's grandmother was one of five Tibetans who arrived in Khar Us with Chagan Gegen in the 19th century during his first visit to Xinjiang. They stayed in Bayanguu of Khar Us, secularised, and today their descendants have developed into over fifteen households assimilated into the Mongol community. According to Orlogjav, the prevailing conception of seven Sum Torghuts of Khar Us is misleading, given that Öölds from Tarbagatai and Zahchin from Mongolia also settled within the Torghuts and can constitute two more Sums. The Öölds were relocated to Khar Us in the 19th century by Chagan Gegen, whereas the Zahchin group escaped from the communist regime of Mongolia in the 1930s and settled in the Tabilhat pasture in Khar Us. Although they lived in a close community until 1970, they have now largely assimilated into neighbouring communities such as the Torghuts and Öölds. When Sheng Xicai was the governor of Xinjiang, he convened most regional leaders of Xinjiang and attempted to assassinate them to strengthen his dictatorship. Aware of this political movement, Minchin Wang escaped to Taiwan via Tibet, Nepal, and India. Regarding the Choras clan in Khar Us, they initially escaped from the Jungar-Qing war and settled in the northern Tenger Mountain as two Sums. Subsequently, the Qing government added one more Torghut Sum under the leadership of Beis Noyan when the Torghuts migrated back to Xinjiang from the Volga region in 1771. Nowadays, the descendants of the Choras no longer recognise their history and simply refer to themselves as Torghuts. Some other Choras from Nilah, Mongol Khüree, and Tarbagatai who survived the war were convened in the Altai region by Chagan Gegen and constructed a Buddhist monastery there. Other Öölds, particularly from Tarbagatai and Bortal, were gathered in Khar Us once again by Chagan Gegen and his Buddhist monasteries. In 1958, the CCP arrested 136 lamas in Khar Us, and only a dozen of them returned in the 1990s. In the meantime, many historical artefacts, including books, were destroyed in 1958. It can be said that Khar Us was one of the most severely afflicted areas of the time.
