Young people who are now engaged in sales are basically fresh graduates. Without any work experience, it is a good choice to accumulate wealth quickly and be familiar with interpersonal relationships. Most sales are based on entities, and we need to fully understand the performance of multiple entities before we can convince customers to buy. In this case, sales staff will tend to know more about the knowledge and technology of entity performance and increase their knowledge. After learning the technology to a certain extent and being fully familiar with it, you can explain the relevant professional details to customers in detail, which is also the main motivation for customers to buy, so they tend to sell again. Of course there are other possibilities! thank you
