This video, through the life history of a single individual, explores how the Khalh Mongolian communities entered Xinjiang in the 1930s and scattered across the regions in the following years. Urtnasan was born in 1946 and grew up in Barkhöl in a Khalh Mongol family. His father, Sancheng, successfully escaped, along with others, from the new communist regime of the Mongolian People’s Republic to Barkhöl in Xinjiang in the 1930s. Although Sancheng had five siblings, they were all scattered across different places due to a series of events such as the pursuit by Khalh Mongolian troops and plundering by Kazakh bandits around 1940. As Urtnasan heard from his parents, Kazakh bandits plundered livestock from Mongolia twice. The Mongolian response to the second raid was crucial as it greatly weakened the bandits’ power. Consequently, those bandits turned their attention to Khökhnuur and Barkhöl, raiding livestock and even abducting young Mongolian females, as he knows several Mongolian young women who married Kazakhs in Barkhöl. In 1963, when Urtnasan was in Barkhöl, the border between Mongolia and China was officially closed off with iron fences, terminating travel across the border. Subsequently, after the Cultural Revolution, Urtnasan joined an industrial group in the Chinese community along with his father. However, he soon moved to Khoshut County in Bayangol, where he acquired a Chinese identity card for settlement and started his private medical career, which he had inherited from his father. Having been born and lived in Barkhöl for half of his life, Urtnasan vividly described the geographical nature of the place and recalled the Mongolian names, which are now on the verge of being altered by other ethnic languages such as Kazakh and Chinese. Among many, the pastures he lived on, including Ikh and Bag Har Gol, Möchin Gol, and Arshaant, were significant to the Mongols in Barkhöl. In the past, Mongols went to Möchin Shil to organise summer festivals, featuring horse racing, wrestling, and other events.
