China's calligraphy is an original performance art of the Han nationality, which is known as: poetry without words, dancing without words; Paintings without pictures, silent music, etc. There are many kinds of calligraphy, including but not limited to seal script (including big seal script and small seal script), regular script (including ancient script and regular script), official script (including regular script and regular script), running script (including running script and cursive script) and cursive script (including Cao Zhang, grass, grass and regular script).
Common regular script, official script and running script are widely accepted and widely used calligraphy forms. Generally not ignorant and ugly.
As for why some excellent calligraphy works are not widely recognized, they belong to the art category and are divided into the minority and the public (music is one of them). For those who like this art form, they will study it deeply, and naturally there is a set of corresponding evaluation criteria, which is relatively unknown to everyone. Simply put, just like painting, I believe many people can't understand Van Gogh's works. However, this does not rule out that Water Lily by a master like claude monet will be widely accepted. A work of art is not judged by the number of people who accept it, but by its artistic accomplishment.
