In a narrow sense, cursive script refers to Cao Zhang and Cao Jin.
Cao Zhang is a sketch of official script, so it originated from official script. This legend was created by the historical travel of Huangmen Mausoleum in the late Western Han Dynasty and Yuan Dynasty. Zhao Yanwei in Song Dynasty said: "Xuanhe, the ancient people in Shaanxi got wooden slips, and the word is Cao Zhang. It was the second day of Yong, and they sent their husbands to crusade against Qiang. Mi Yuanzhang wrote: Cao Zhang was played by Cao Zhang. Today's test uses both, and aesthetic feeling is applied to the text. Since ancient times, it has become easier to establish a primary school family, so the big seal has become a small seal, and the small seal has become an official; Longer than it, it is complicated to be a servant. Then it's natural to play with the articles and learn to play with the grass. " Therefore, although the grass is famous, the official script is still there, and it is not far from Liang Yao's official position. "This theory is more credible because it can be played in chapters. Although the font of "Cao Zhang" has been simplified to "Lishu", it is still slightly wavy. If we look at the wooden slips in the early Han Dynasty (above), we can see that the early "Cao Zhang" is actually a rough variant of "official script" in an emergency. Therefore, there is no certain standard for its brushwork and structure. It was not until Zhang Zhi and Cao Zhang in the Eastern Han Dynasty that it matured and reached its peak in the Wei and Jin Dynasties. Among them, famous calligraphers, such as those in the Wei and Jin Dynasties, the statues of emperors in the Wu Dynasty and those in the Jin Dynasty, are all called "masters".
Calligraphy posts handed down from ancient times include Ode to the Teacher by You Shi, Zhang Zhishu by Chunhua Pavilion, First Aid by Xiang Di, and Reading Instrument Post by Suo Jing.
This grass is also called "grass". A cursive script. It started at the end of Han Dynasty. This is an innovation of Cao Zhang. This grass is a kind of grass that inherits Cao Zhang, adapts to the development trend of official script opening, line style and shape change, further omits Cao Zhang's strokes and waves, and becomes more free and easy.
According to historical records, this grass was created by Zhang Zhi in the Eastern Han Dynasty, and the world called Zhang Zhi "the sage of grass". By Wang Xizhi in the Eastern Jin Dynasty, he had learned from others, especially Seventeen Posts, which was the representative work of cursive scripts in previous dynasties. Wang Xizhi's son, Zhi Yong of Sui Dynasty, Sun, Zhang Xu and Huai Su of Tang Dynasty were all cursive masters. Among them, Zhang Xu and Huai Su are particularly famous for their personalities (commonly known as "getting drunk"), which have a great influence on later generations.
