Sell TV and talk about it

I have been in this business for many years. Let me tell you a secret. First, you should know all the functions and performances of several TVs you sell, including advantages and certainty. Further, you need to know the LCD model, maternity leave and motherboard scheme used in your product. This is self-knowledge. You are a qualified TV salesman after completing this step, but being excellent is not enough. Second: you don't need to know the advantages and disadvantages of the main competitors' products deeply, but there is one thing: what screen does the other party use, is it a new screen or a second-hand screen, and how stable is the motherboard? You need to have a general understanding of these. If you don't know, you can go to their online store to comment, basically just look at the bad reviews. Knowing yourself and your competitors, as long as you are not clumsy by nature, it is natural to promote products.
