As far as I know, Hebei Zhongshu Association is a branch of Hebei Calligraphy Association, which has rich experience and resources in the field of calligraphy education. Their training courses are arranged in different levels to meet the needs of different students, and students from beginners to advanced levels can find their own courses.
In addition, their training courses will regularly hold various calligraphy competitions and exhibitions to provide students with opportunities to display their works, and professional judges will evaluate and guide their works.
To sum up, Hebei Zhongshu Association's calligraphy professional grading training class should be an institution that provides professional guidance and holds competitions and exhibitions. If you are interested in calligraphy and want to improve your level, I think this training course is worth choosing. Please note that the specific situation may require you to consult the relevant institutions for more detailed information.
