What I was trying to figure out was the Sichuan art (4,800 - 1,100 BCE) that is so very different from other Chinese art.
Did you read The Tarim Mummies by JP Malloy and Victor Mair? I've read that book three times and still cannot absorb it all. Another good one on the same subject is The Mummies Of Urumchi by Elizabeth Barber.
My mind is gone too. lol
