1. Content: It's best to communicate with your students in advance and make clear what they want to know about the product. Don't talk for a long time because people already know or don't want to hear it. Remember, remember!

2. Form: flexible and diverse. Don't tell it all by yourself, people will fall asleep. You can turn the knowledge points you want to talk about into topics, instill product knowledge through knowledge contests on the spot, and make the classroom active at once.

In addition, don't do a lot of PPT, use more pictures and tell more cases. '

Good luck!
