Calligraphy terminology. The skill of stippling with a pen. The "eight-character method" calls the pen "qi". In ancient times, the cracked sacrifice was called a tomb, and the method of pressing was used as the tomb, which meant that the pen was spread out as far as possible to make it burst. There is also oblique pressure called pressure, and horizontal pressure called wave. Li Shimin, Emperor Taizong of Tang Dynasty, wrote in The Art of Calligraphy: "You have to fight with a pen, but you are proud of it."
