The emergence of cursive script was due to the frequent wars in the Qin Dynasty. Battles and attacks were carried out simultaneously. Military letters were exchanged and pigeons were flying. Due to the military situation, seal script and official script were time-consuming. They tended to save time and pretended to write official script. Jincao, created by Zhang Zhi at the end of the Han Dynasty, transformed the original practical cursive script into a more ornamental style.
The beauty of cursive calligraphy art is reflected in two aspects: the superficial beauty of appearance and the deep beauty of connotation. Some people summarize the beauty of cursive calligraphy art into ten points: the flying dots and strokes, the interest of the pen and ink, the changeable structure, the vivid composition, and the graceful lines.
It is said that the blood is connected, it is said that the charm is natural, it is said that the transformation is ups and downs, it is said to be majestic, it is said to be strange and unrestrained. In short, the beauty of cursive calligraphy art is as if it is silent but has the meaning of poetry, is silent but has the divine form of dancing, is colorless but has the colorfulness of painting, and is silent but has the melody of music.

Development of cursive script:
From the perspective of the development of cursive script: the development of cursive script can be divided into three stages: early cursive script, chapter cursive script and modern cursive script.
Early cursive script is a calligraphy style parallel to official script, generally called official script. In fact, it is mixed with some seal cursive styles.
The early cursive script broke the rules and strict rules of official script and was a hasty writing method. It's called "Zhangcao". Zhangcao is an elegant cursive style that combines early cursive script and Han official script. It has clear waves, the strokes are connected in a "wave" shape, the characters are independent, the characters are all square, and the strokes are horizontal. Zhangcao was most popular during the Han and Wei dynasties. It was revived in the Yuan Dynasty and transformed into the Ming Dynasty.
At the end of the Han Dynasty, Zhangcao was further "cursed", removing the traces of official script strokes, and the strokes between the upper and lower characters were connected. The radicals were also simplified and borrowed from each other, which was called "Jincao". Jincao evolved from Zhangcao's elimination of waves and challenges. Jincao style has been popular since the Wei and Jin Dynasties. In the Tang Dynasty, modern cursive writing became more indulgent, with continuous and sweeping strokes and various character shapes. It was called "kuangcao", also known as big grass.
Today, the aesthetic value of cursive script far exceeds its practical value. Cursive script is a combination of dots and dashes of words according to certain rules, with a simple structure and borrowed radicals. It is not just random writing.
