What is the difference between the calligraphy written by modern people and the calligraphy written by ancient people?

Modern calligraphy is too utilitarian, and calligraphy by famous artists is often sold at auctions at high prices. Even if they are given to friends, most of them are with a complacent heart, and most of them are imitations with insufficient innovation. They strive for utilitarianism and relationships. The layout is too small.

The calligraphy of the ancients was mostly based on exchanges and exchanges, and there were also many people who were proud of their talents, but they lacked a lot of utilitarianism and their bearing and foundation were not comparable to modern calligraphy.
