If you like Mr. Pang's handwriting, copy it carefully. Don't fish for three days and dry the net for two days. Be calm and dedicated. When stippling and basic structure have three or five shapes, you can change posts, yes, change posts, and change copybooks of other calligraphers.
If it is a hard pen, I recommend Lu Zhongnan, Tian Yingzhang and Shen Honggen to you. If it is a brush character and the direction of regular script, you can choose "Yan, Liu, Europe and Zhao" according to your preference; There is also a regular script called Weibei, which is not suitable for beginners. As for other calligraphy styles, such as seal script, official script, running script and cursive script, that is later. If you really love calligraphy from the heart for unknown reasons, then go for further study. Of course, the premise is that you'd better have the basic knowledge of regular script.
Finally, I return to the topic of how to practice regular script well. I'm telling you, this can't be finished in a few words, nor can you understand after I say it. Buy a calligraphy book with theory and model essay and have a good look. Send you a pair of couplets: copy two gu heng as the law and learn three pen and ink as the truth.
