In this case, the rules of each shopping mall depend on the specific situation. Let me tell you about it in combination with my own situation. I am a jewelry major myself. I majored in jewelry design. Now come out for an internship. I work as a shop assistant in a shopping mall. To put it bluntly, I stand at the counter. If you want to go to a shopping mall for an internship, most of them will do it, because it is very simple at first, and you don't need any strong professional knowledge, as long as you have a talking mouth. Well, if my other classmates go to the mall, they also do processing and hand-painting, which is particularly good and outstanding, so they do design, but at first they let you copy and won't let you take over the work. Generally speaking, going to the mall means doing more sales.
