The writing tool of the ancients is a brush, and calligraphy also refers to a brush. Thousands of years of cultural accumulation, every day someone writes, everyone writes. No comparison, no harm. It's embarrassing to write it. It looks good, but it's ugly and shameful.
Now everyone is typing and writing less, let alone calligraphy. And it is used in too few occasions.
Mentality, demand and diligence can't compare with the ancients. How can we surpass them?
