Now the office environment has basically become the world of modern tools such as computers and printers. Even if you write by hand, you can't send a writing brush. You should use a pen, ballpoint pen and fountain pen. The brush seems to be far away from us. In fact, many people miss the time when they used brushes to display their talents. Now, if I want to appreciate China's calligraphy, I can only write by myself or receive letters from calligraphers. They never use email. They say that writing with a brush is more cordial and they can show their sincerity to their friends. Calligraphy is really in a dilemma in terms of practicality. But I think calligraphy, as an art form, will be passed down forever. While the brush has lost its practicality, calligraphy has become more and more elegant and professional, and its aesthetics is more prominent. Brush has become a unique artistic expression tool. I think, because of this, people are even more reluctant to forget the era when the brush flourished.
