@Chen_Li The overall style is simple and the viewpoints are clearly arranged. The font spacing in the second picture is a bit small, which is not very convenient to read. The font in the third picture is a bit compressed and can be reduced a bit

@cihanyuelin The author uses Duolingo's examples to express his own views. The discussion is divided into points and the content is clear. However, the font color matching is not very clear and can be improved.
