Pang Zhonghua, Tian Yingzhang, Jing Xiaopeng, and Liu Qingchun are all very good at regular script and running script. You can try it.
I prefer Liu Qingchun’s running script. It is clear and neat, and it is not difficult to practice.
Jing Xiaopeng’s cursive calligraphy is more grand and cursive, with a feeling of flying dragons and phoenixes.
Pang Zhonghua seems to be Jing Xiaopeng’s teacher, and his calligraphy has a sense of character.
Tian Yingzhang’s regular script is very good, and now many people practice his regular script.
