For example, just like jadeite, regular jadeite will have an appraisal certificate, but if you are in the industry, you will know that you can buy this certificate in Nanyang or the origin of jadeite, which is very cheap. A piece of jade worth 2,000 yuan in a shopping mall, the actual value may only be 200 yuan, and its certificate can only be bought in 20 yuan. If the certificate is made on the spot, the photo of the certificate is the same as that of the jade.

Apart from the cost, a large part of this 2,000 yuan is earned by the merchants, and the other part is given to the law enforcement department. Otherwise, who will sell him a false certificate?
