The key to writing is the information it carries. As for calligraphy, it is only the last section.
Especially after the invention of cursive script, it was purely forced+forced.
But this is not surprising.
After the unification of China by Confucianism, Confucian scholars like to be mysterious when writing, and it is best to show their high level by making others unable to understand.
The invention of cursive script made Confucian scholars more valuable. Wouldn't it be more amazing if others didn't even know their own words?
Calligraphy is meant to be more beautiful.
Later, it became something that literati kept up with each other and pretended to force each other.
As for the role that words should play, who cares!
