The Zakhchin (Mongolian: Захчин) is a subgroup of the Oirats residing in Khovd Province, Mongolia. Zakhchin means 'Border people'. They are so called because they are originated form the border garrison (mainly from Torghud, Dörbet, Ööld) of Dzungar Empire. They originally speak the Zakhchin dialect of the Oirat language, but actually pure Oirat language is used by elder generations, younger generations use a dialect being under a strong Khalkh influence.
The Zakhchins conquered by the Manchus of the Qing dynasty in 1754 and controlled by Zasagt Khan aimag's Tsevdenjav gün, then moved to Zereg and Shar Khulsan. One khoshuu with 4(+1) sums were designated for them and noble Maamad (Mamuud) zaisan became the chieftain but Mamuud killed by Zungharian king Amarsanaa later and the Zakhchins revolted together Amarsanaa against the Qing dynasty.
The sums were:
Spit out the poison
That plastic motive
The soothing pain that feeds the hole
A carnage path of one-time friends
A stepping stone to personal ends
A line that piles high
An art of trend
Champagne delusions
Contorts and bends
The seething mass which consumes deceit
The frozen glance
Burn obsolete
All we are is one section
