Shenzhen Jewelry Fair is an exhibition, not an auction. Jewelry Fair is usually a place where jewelers and spectators display their products and exchange business, and auction is a form of activity to buy and sell auction items. Although there may be some activities related to jewelry auction in the jewelry exhibition, such as jewelry special auction, not every jewelry exhibition will have an auction. Therefore, if you want to participate in the jewelry exhibition, I suggest you know the specific contents and activities of the exhibition in advance to determine whether there are related auctions.
