What is the difference between modern calligraphy and ancient calligraphy?

The ancients paid more attention to norms and methods and had a more correct attitude towards characters. Although the standard of beauty in ancient calligraphy may not be clearly marked, the beautiful words in ancient times can generally be recognized by most people.

Modern calligraphy is more popular if it can be "innovative", and the standard is vague. Some people loudly applaud the same words, while others find them extremely ugly. There is a shadow called "fun" beside modern calligraphy, which shakes from time to time, affecting people's judgment on the beauty and ugliness of words, so it is difficult to have good words.
