The PPT of etiquette trainer must be concise and suitable for the training object. Look for different styles of templates according to different objects. I recommend you to find materials on 1PPT.
PPT includes text, video, audio, animation, small elements and other decorations. For example, A contains B, A is contained by C, and B is contained by C? It is difficult to answer directly, but it is clear at the moment of drawing that pictures are more intuitive than words.
A page of PPT is about 3 to 4 lines, each line has five or six words, the font size is greater than 24, and there are at least two fonts. Others are details, and everyone can do more. The core of etiquette trainer PTT production is the audience.
