The ancients said that you can't be called a calligrapher if you are not good at small letters. I quite agree with this view. However, many calligraphers I see now write cursive scripts. I don't know how many people can really write regular script! My understanding: there is tradition, but it is not only tradition, but also personality and knowledge, which can open up a new look. This is the calligrapher in my heart. I think King, Yan Zhenqing, Zhao Mengfu and Yu Youren can all be counted. Those who disagree can argue with me.
Whether to write in block letters is not limited, and block letters are also acceptable. Whether it is a cursive script or not, it is not rigid, and the running script is ok. These two items are the limits of skill test, but they are very general and not prominent. For example, Miffy only writes excellent books, so the history of books remains fragrant.
