Open class of Professor Wang Lichun of Shenyang Normal University: Calligraphy Aesthetics and Basic Techniques. Although the whole open class lasts less than six hours, it is vivid and meticulous, which is no different from the calligraphy elective course that took 2 credits last semester. The content of the course ranges from the use of pens and racks in the primary stage to the aesthetics of cursive and official scripts in the advanced stage. Teacher Wang's lectures are very lively and humorous, not boring at all. The key is that I can really learn a lot every time I watch a class, so I feel that every class is finished in a few minutes, and I have been taking notes carefully, which is very interesting to learn.
