Although I personally have no experience in physical store sales, I am very proficient in jewelry professional knowledge and do online sales. Personally, I think that first of all, jewelry knowledge should be excellent, so that customers feel that you are very professional and feel free to buy. Secondly, you can easily talk about other topics besides jewelry promotion, instead of selling your goods blindly, which will make customers feel very disgusted. Once customers like to chat with you, they will naturally trust you, and then there will be endless bills.
