The first sentence said: "Hello, welcome to XXX jewelry!" Tell your store, let customers know your store and remember your store. Another reason is that you have to advertise in the customer's ear to introduce the quality of the product origin and "buy" the customer's psychology with professional knowledge. This kind of advertising effect is many times stronger than that on TV and on the plane, because you really told him! I believe that customers will not be disgusted, and they can learn knowledge while buying things. It doesn't matter if you can't make a deal, at least you left a good impression on your customers and your enthusiastic customers remembered it. Maybe I'll call you next time.
