2. There are hidden dangers that weaken confidence.
Are Europeans in good health? Sure! But many people made a mistake and wrote the European style very vulgar. Ou Yangxun's regular script is very thin, hard and ancient, but now what many people write is flashy and unremarkable, which is far from the inner meaning of European style.
European style is good, but not easy to learn. Ou Yangxun is known as the master of structure. His structure is so rigorous that you can't move at all. It is extremely difficult for beginners, and it is easy to dampen their confidence in learning calligraphy.
