Can calligraphy be taught by itself?

Of course, hard pen calligraphy or soft pen calligraphy, first of all, we must face the copybook and figure out how to use the pen and how to do it. First learn the basic strokes, then practice the font structure, and finally master the composition. Hard-pen calligraphy is not as delicate as soft-pen calligraphy and easier to practice, so copybooks are not particularly recommended. For soft pen, official script "Cao Quanbei" and so on; Regular script Yan Zhenqing's Diligence Monument, Liu Gongquan's Mysterious Tower, Ou Yangxun's Jiucheng Palace Ritual Spring Inscription, etc. Wang Xizhi's Preface to Lanting, Su Shi's Huangzhou Cold Food Post, etc. Generally, you should start with regular script, and it is best to choose copybooks according to your preferences and font characteristics. The important thing to practice calligraphy is to stick to your heart for at least an hour every day. When I first started practicing strokes, it was the most boring. Compared with what I said before, I wish you success at last!
