There is a shop to buy Hetian jade on Taobao.
Don't buy it. I'll calculate the cost. The labor cost per kilogram of 800 yuan with the worst quality of Hetian jade is manual 100 yuan. Mountain materials are wasted a lot. You don't have to consider jade below 300. Don't trust any master, professor or real master unless you fake it and use jade powder to tune it. How many knives does a piece of jade have? Let me show you my mountain material.
