First of all, the calligraphy grade examination and paragraph evaluation are both "virtual" things, which are not worth your time. It is true and "real" to practice the basic skills in a down-to-earth manner. Calligraphy Grade Examination is a skill training and evaluation system for China painting and calligraphy learners sponsored by the Examination Center of the Ministry of Education. This is officially and nationally certified. Mainly divided into three levels: primary (1-3), intermediate (4-6) and advanced (7-9). It's the first time I heard about calligraphy. I'm sorry I'm ignorant. It should be unofficial.
Hope to adopt
