The trips to the Great Wall and tombs always include a stop in a jade factory (I read it in VT prior to go, and… got it there).
The usual quick look at some people working (nothing new, I had already seen it, in Thailand, or India, or… both), and a technical explanation about the process and the different qualities of jade. That’s serious and useful!
Then… it’s up to you, to buy or not. The prices are high (shh… I escaped… and Fernanda didn’t notice yet that there was no jade in our containers back home… shh!) and the display very appealing.
If you don’t have my luck (this time… only this time!), why not to use the good technical information in a cheaper place?
