Chinese appear to be the only ones ever surprised to find that there's a Scotsman in the Woodpile eh!
The Chinese describe various groups of Hsiung Nu horse nomads in similar terms: the Yellow Hairs, Green Eyes, etc. They were considered dangerous and untrustworthy barbarians, but then who wasn’t?
The Hsiung Nu were contemporary with the various “Scythian” peoples described by Herodotus, and the later Sarmatians and Alans. Large people with a martial culture. Intriguing similarities in animal style art as well, although that could as easily be due to trade as ethnicity.
