How to write calligraphy with a brush:
During the strokes of the brush, pinch your thumb and index finger to ensure that the strokes do not fall off; on the outside of the pen, place your middle finger under your index finger. This not only enhances the pinching force of the index finger, but also plays a role in hooking the strokes. The pen is inside. The nail flesh of the ring finger is on the inside of the pen barrel and plays the role of pushing the pen outward; the little finger is attached to the lower part of the ring finger and assists the ring finger in pushing the pen outward.

History of brush calligraphy:
As a writing tool, the brush has a very long history. It has been left on painted pottery as early as the Neolithic Age. There are traces of brush painting. Although no actual writing brush has been seen before the Western Zhou Dynasty, some signs of the use of brushes can be found in prehistoric painted pottery patterns and oracle bone inscriptions from the Shang Dynasty. In the Eastern Zhou Dynasty, brushes were widely used to write on bamboo slips and silk.
It can be seen that the writing brush originated before the Yin and Shang Dynasties. The earliest writing brush can be traced back to about 2,000 years ago. A calligraphy brush from the Spring and Autumn Period was discovered in the tomb of Marquis Yi of Zeng in Leigudun, Suizhou City, Hubei Province. This brush is the earliest brush discovered so far, and is a rare and precious material left over from the ancient times. During the Spring and Autumn Period and the Warring States Period, the names for the pen varied from place to place, including "Bi", "Yu", "Fu" and other names.
It was not until the Qin Dynasty implemented "the same text for books and the same track for cars" that the various names of the pen were unified as "pen". According to legend, Meng Tian, ??a general of the Qin Dynasty, once took sheep hair to make brushes in Shanlian Village, and was regarded as the ancestor of brushes by the local people. It is also said that Mengtian's wife Bu Xianglian was also proficient in pen-making skills and was worshiped as the Empress of the Pen. By the Han Dynasty, pens had become more sophisticated, and Lu Xie was a master of pen-making at that time.
