Origin of the Alans

[Merlkir]

Reading Jeannine Davis-Kimball's "Warrior Women", she talks about excavations of a stone house at Barkol, which she relates to the Kangjiashimenji petroglyph culture:

"When Wang Bing-Hua excavated the house, he found about thirty skeletons lying on the floor and among the artifacts were two very large bronze cauldrons of the precise style used by the nomadic Yueh Chich. This confederacy has occupied this region from the fifth to the third century BC before they were driven eastward (I guess a typo here) by the Hsiun-nu..."

Sadly I wasn't able to find anything about this dig at Barkol, or what the supposedly Yuezhi-defining bronze cauldrons were supposed to be.
