What are the characteristics of the works of German and artistic calligraphers?

Deyi teacher's calligraphy is moist and beautiful, steady and mature, rigorous in statutes and vivid in conception. Deyi, whose real name is Guo Xianghua, whose name is Wu Sheng, 1965, studied books for nearly 40 years. Kay, Xing, Zhuan Xu, Li and Cao are all involved. Good at fine print and running scripts is also ok. In recent years, I like to copy classics and read ancient books, especially Buddhist scriptures, so as to cultivate my mind and prove myself.
