First of all, introduce yourself briefly:
Hello, Director Zhang, this is Zhang Lele from Education Company. I'm here to ... I want to meet/communicate with you.
If the director is still listening to you without rejecting you, then you should give full play to what you want to say and make it clear. Pay attention to eye contact with the director when communicating. Don't speak too fast. Pay attention to the director's reaction. If the director nods or leans forward, you can ask the director any questions, so as to keep the communication smooth.
Before the end of the conversation, the better the next meeting or phone call, such as:
Director Zhang is in a hurry this time. Maybe you need some time to digest our information. When do you think I can see you again and answer your questions about our products?
Say some kind words at the end, such as delaying your time, wishing you good luck in your work, happy company, and thank you for listening.
