How about Lu Dingshan's regular script copybook practice?

It's good.

Lu Dingshan absorbs the essence of ancient and modern famous calligraphy, whether it is the artistic calligraphy styles of Kai, Xing, Cao, Li, Zhuan and Wei, or various artistic characters such as imitation of Song, boldness and variation, and tries to explore and innovate on the basis of earnestly inheriting the tradition, and gradually forms his own style.
