Mongolia Spinning
No evidence of wheels used in medieval times found, which makes a certain amount of sense given they were a nomadic culture and moving around with something as large as a wheel (even one that is typical of Asia at the time) could have been problematic
From looking at pictures of historical reenactments, they appear to have used bottom whorl drop spindles. But these are reenactments. I’m not finding primary sources, or even secondary.[1]

Hohhot reenactor spinning. I’m dubious, as that spindle looks more European than anything else I’ve seen doing this research, but I’m good at being wrong.[2]
Fibers were primarily goat (cashmere is and was huge) camel, and sheep, as raising plant fibers was (and is) not really a thing.[3]
