I also sell jewelry, and my conclusion is: in the early stage of trial work, we must first understand the types and styles of jewelry in the store. At least it's clear when customers ask you what kind of things to put where. The other is through practice. Only by selling in person can you know what you need to master in this industry. . . . . I have been working for more than a month now, and my performance is good. I wish you luck, too. . .
