Hi Ruijie,
I am happy to read your blog, and I very much agree with your views. First of all, I agree with what you said not to put too much text in the PPT. Because in my opinion, what the audience needs is a narrator to explain, not to watch a reading on the screen. If there is too much text, it will make the reader feel very boring, and may not attract the attention of the audience. So I think you’re right. The text of a PPT only needs to write some keywords or mark the key points with markers.
