How about Pang Zhonghua's hard pen calligraphy?

Pang Zhonghua's font is not very recommended, but if you think his font is good, you can learn it. Our calligraphy teacher said that Pang Zhonghua's son should not practice calligraphy. In my opinion, Ponty has a lot of sick pens, such as the frequent "nail head". LZ can understand what "nail head" is, and it is recommended to practice European style, because it is easy to convert European style regular script into other fonts. As the saying goes, "it is difficult to input a word, but it is more difficult to output it", which means it is difficult to refine a word. One more thing, it is suggested that we should start with the brush calligraphy, practice it well, and pick up a hard pen calligraphy for nothing. . . Can it be adopted?
