Beltir

Khakas (Khakas: Хакас тілі, Xakas tili) is a Turkic language spoken by the Khakas people, who mainly live in the southwestern Siberian Khakas Republic, or Khakassia, in Russia. The Khakas number 73,000, of whom 42,000 speak the Khakas language, most of whom are bilingual in Russian.

Traditionally, the Khakas language is divided into several closely related dialects, which take their names from the different tribes: Sagay (), Kacha (), Koybal, Beltir, and Kyzyl. In fact, these names represent former administrative units rather than tribal or linguistic groups. The people speaking all these dialects simply referred to themselves as Tadar (i.e. Tatar).

The people who speak the Fuyu Kyrgyz language originated in the Yenisei region of Siberia but were relocated into the Dzungar Khanate by the Dzungars, and then the Qing moved them from Dzungaria to northeastern China in 1761, and the name may be due to the survival of a common tribal name. The Yenisei Kirghiz were made to pay tribute in a treaty concluded between the Dzungars and Russians in 1635. Sibe Bannermen were stationed in Dzungaria while Northeastern China (Manchuria) was where some of the remaining Öelet Oirats were deported to. The Nonni basin was where Oirat Öelet deportees were settled. The Yenisei Kirghiz were deported along with the Öelet. Chinese and Oirat replaced Oirat and Kirghiz during Manchukuo as the dual languages of the Nonni-based Yenisei Kirghiz. The present-day Kyrgyz people originally lived in the same area that the speakers of Fuyu Kyrgyz at first dwelled within modern-day Russia. These Kyrgyz were known as the Yenisei Kyrgyz. It is now spoken in northeastern China's Heilongjiang province, in and around Fuyu County, Qiqihar (300 km northwest of Harbin) by a small number of passive speakers who are classified as Kyrgyz nationality.
