Do you have to practice running script and regular script with calligrapher's hard-pen copybook?

I'm happy to answer your question. I have been practicing calligraphy for twenty years. The copybook is very important. Once this post is confirmed, it is a replica of a decade's cold window. Observe and think, don't post both at the same time. You can practice running script and contact regular script at the same time, but don't put both running scripts at the same time. You should study and live. Stickers should be stuck to death. There is no need to practice the same master for regular script and running script, so choose to paste according to your own hobbies. Then I'm dead. I am Ou Yangxun in regular script and Zhou Huijun in running script. Finally, I tell you that regular script and running script can be divided into two different things. Wish you success!
