There are few original stones in Shenzhen. Generally, the original stones are in Zhaoqing and Sihui, and Sihui has the most finished and semi-finished products. You can go to Sihui jade rough stone wholesale market, where there are rough stone auctions and on-site purchase and cutting every day. I saw a man spend 100 to buy a piece and cut it on the spot, worth 20 thousand. Another person spent 100 yuan to buy two rough stones and cut them out.
