Mysterious statue

I was looking up what happened in the 8th century and found this. From a 2011 Wall Street Journal article about this fellow:

Made in China during the latter part of the eighth century, this unusual Tang dynasty burial figure today sits on a shelf in the Museo di Arte Orientale (MAO) of Turin, Italy, exuding as much mystery as he does energy. To date, nobody can say exactly who or what he is—his clothes, his pose, his expression don’t add up. Even his manufacture is atypical: While almost all other known burial statuettes are hollow and cast in molds, this one is solid clay and appears to have been sculpted by hand.
