Note 2 — Chapter XIII · The Symbolism of Jade
Reading edition
When the prehistoric Chinese settled in Shensi, they found jade in that area. “All the Chinese questioned by me, experts in antiquarian matters, agree”, Laufer writes, “in stating that the jades of the Chou and Han Dynasties are made of indigenous material once dug on the very soil of Shensi Province, that these quarries have been long ago exhausted, no jade whatever being found there nowadays. My informant pointed to Lan-tʼien and Fêng-siang-fu as the chief ancient mines.”2
