I happened to practice Panghetian. In my opinion, Pang Zhonghua's calligraphy is neat and neat, and he is good at hard pen calligraphy. Beginners can easily see the effect and are suitable for getting started. Tian Yingzhang's calligraphy comes from the European style, with strong strokes, rigorous structure and excellent calligraphy hardness, which is suitable for people with a certain foundation to further improve.
My suggestion is: you can practice pang body first, find a rule as soon as possible to enhance your confidence, but be careful not to form a habit; Practice the field again to improve the level of calligraphy. If you develop from writing to loving calligraphy, you can go back and practice Tang Kai to improve the taste of regular script. Wish you success!
