I bought a piece of jade when I was traveling in Zhangjiajie, and negotiated with the merchant that he could return it and send it to me.

Personally, I advise you not to return this. Most of these people are profiteers, cheating people in popular tourist attractions, cheating one is another! If you send it, people will probably refuse to refund the money on the grounds that the jade was broken when they got it (not excluding cheating you with the courier group). Of course, the jade that the boss took pictures of you may be yours, or it may be as broken as the one prepared at home. Finally, you, the money is gone, and the jade is gone! Personal advice, but not all profiteers.
