What hard-pen calligraphy courses are there in Pang Zhonghua?

Pang Zhonghua's hard pen calligraphy is very good. His hard-pen calligraphy is a combination of official script and Weibei style. It is a model of our new generation of hard pen calligraphy. The word is slightly flat, and the pen for running calligraphy. Worth popularizing by all of us. Because we learn regular script, most of us learn from Ou Kai, so we misunderstand that Pang Zhonghua's hard-pen calligraphy regular script is not as good as seal cutting (Tian Kai).
