What is the significance of anti-horizontal calligraphy?

As the name implies, vertical calligraphy is a form of calligraphy with horizontal writing and reverse writing. The birth of anti-horizontal calligraphy made the huge vertical calligraphy works four feet, six feet or even eight feet apart easily completed without moving the rice paper, and the speed of calligraphy creation doubled. In particular, combined with Mr. Xie Yurong's original bottle pen, a few minutes can write a vertical calligraphy work of hundreds of words on the rice paper separated from Zhang Er without dipping in ink. It can be said that the appearance of calligraphy with bottle pen and calligraphy with anti-horizontal style has undoubtedly promoted the development of calligraphy performance in China.
