If you want to learn regular script, it is recommended to start with Wei Bei. Wei Stele, commonly known as Wei Kai, is a kind of regular script that transitions from official script to regular script. There is a lot of room for development in learning this kind of regular script. This is the common sense of many authoritative calligraphers. Nowadays, some calligraphy students learn Tang Kai, which is not the best choice. Because the regular script of the Tang Dynasty was already very mature, it was extremely neat and beautiful, and there was no room for development. If you continue to learn it, your writing will become more vulgar and lack the ancient meaning. The steles of the Wei Dynasty include "Zhang Menglong Stele", "Li Bi's Epitaph", "Zhang Heinv's Epitaph", "Twenty Products of Longmen", etc., which are optional. I am currently studying the Epitaph of Meng Jingxun of the Northern Wei Dynasty. Its style is close to the Epitaph of Li Bi. Of course, I have also studied the Epitaph of Li Bi.
