Why do calligraphers like to write ugly words now?

Now those so-called calligraphers deliberately write differently from normal people in order to impress others and highlight their own differences, and they call it art. People who don't understand it don't understand art.

Many people write quite well before they become famous. Once they become famous, they will deliberately write ugliness to attract people's attention in pursuit of fame and fortune. If you want to learn calligraphy seriously, I advise you to practice it on a down-to-earth basis.
