What kind of videos are included in the recently arranged report?

Because I am currently working for guoxin education and I am very interested in the student donation project I proposed a year ago, I am currently making a "Half" effort in this case. Of course, you don't have to worry about it, as long as I participate in this project, this project will always benefit the country and the people. In fact, I dare to speak like this because leaders here agree with this practice, I have never thought about commercialization, so the nature of this matter will not change. I still cannot tell you how to implement it!
I personally have taken part of a 66-day enterprise training course, so I am also stepping up preparation, so my video content may be slightly adjusted, but it is a bit gratifying, the database video will certainly be made by SQL2005. In the future, we will adopt a direct thinking approach to guide and stimulate the video audience to learn more and think.
The next step is to explore what kind of videos won't let viewers fall asleep.
The reason for this question is that I fell asleep when I watched my previous video a few days ago. So I have been reflecting on what kind of style is not a sleep, what kind of video can stimulate everyone's enthusiasm and motivation for learning.
I have summarized the following points:
1. Intonation speed;
2. Add more entertaining elements;
3. Guided explanations of knowledge rather than infusion;
Now, I hope you can come up with me to learn more practical knowledge...
