When the Eastern Torghuts migrated to Xinjiang, the Qing government relocated them to various places within the region. One group was settled east of Jargalant river in Khar Us as Beis Banner, which was divided into three Sums: Ikh Khüü, Dund Khüü, and Bag Khüü, representing the eldest, middle, and youngest sons, respectively. However, the middle son's group consisted of the Choras clan, part of the Ööld groups who had fled to Khar Us from the Ili region following the Qing government's large-scale purge in Ili. According to local elders, about 54 households successfully arrived in Khar Us at that time. Initially, they settled around the river basin known as Narin Gol, where they established an Oboo worship ritual site under a single aristocracy until the 1930s. By the 1940s, these Choras people had gradually moved to the Salhit pasture and were eventually absorbed into the Torghuts, thus being recognized as Torghuts.
