Member of Tian Yingzhang China Calligraphers Association, hard pen is absolutely good, running script is not good; Lu Zhongnan's hard pen is also first-class, so I don't know how to use the running script. It should be noted, however, that their profound brush calligraphy skills and solid basic skills, especially copying Ou Kai, should be an important reason for their high achievements in hard pen calligraphy. But Ou Kai is too rigid and easy to write to death.
I admire Qin, a member of China Calligraphers Association. Pen regular script is absolutely first-class, regular script is dignified and smart, running script is elegant and blunt, and it can be put away freely. Especially easy to use.
