According to historical records, the earliest school of regular script was created by Yan Zhenqing in the Eastern Han Dynasty. He advocated "taking statutes as the body, keeping simplicity to get the spirit" and paying attention to standardization and accuracy, making regular script a standardized writing form popular all over the country. In the Tang Dynasty, regular script reached its peak and became the mainstream form of official documents and calligraphy. The works of Tang Dynasty calligraphy masters Wang Xizhi, Huai Su, Ou Yangxun and others were regarded as regular script classics, which have influenced it to this day.
Regular script is not only the standard writing method of official document writing, but also widely used in the field of calligraphy art. In the Song Dynasty, Su Shi, Mi Fei, Zhao Mengfu and others further developed regular script and formed their own style and characteristics, which was used for reference and imitation by later calligraphers. During the Ming and Qing Dynasties, the position of regular script was more stable. Many famous calligraphers, such as Wen Zhiming, Tang Yin and Shi Tao, are good at this writing method, and have successively created many excellent regular script works.
In a word, regular script, as one of the most standardized and accurate writing forms in China's calligraphy, has experienced a long development process and produced various schools and variants in different historical periods. It is not only an important part of cultural tradition, but also one of the essences of China's calligraphy art.
