How to practice calligraphy with copybook and hard pen calligraphy

I recommend a copybook by Gu Zhongan, which contains all kinds of cursive scripts. I used to practice calligraphy temporarily for two months, and I used this copybook, which felt good. In addition, I suggest you practice hard pen and brush as an aid, so that you can improve faster. You can choose any one of European style, Yan style, Liu Ti and Zhao Ti according to your personal preference to lay a good foundation for yourself. With a good foundation, progress will be faster. Not much to say, the cover of the hard-pen copybook recommended for you is below. Good luck in the exam!
