2. Ou Yangxun (557-64 1) unified the style of regular script, Yan Zhenqing (709-785) created a bold style, and Liu Gongquan created a style that won by strength.
3. Calligraphy is the most distinctive art form of the Chinese nation and an important part of China culture. Over the past 4,000 years, countless outstanding calligraphers and precious calligraphy works have been produced. These calligraphers formed different styles in their works, which were respected and inherited by later generations and had a very important influence on China's calligraphy art. The classification of large fonts mainly includes regular script, running script and cursive script. Because regular script characters are easy to identify and universal, they are more common in use. Regular script was initiated by Zhong You, developed by Erwang and innovated by Wei Bei. In the Tang Dynasty, the regular script with completely different styles in Wei and Jin Dynasties was unified. This unified work was carried out in Ou Yangxun (557-64 1), Yu Shinan (558-638), Chu Suiliang (596-658) and Chu Suiliang, four famous people in the early Tang Dynasty. The real regular script didn't mature until the Tang Dynasty. The main regular scripts are: European style, Yan style, Liu style, Wei stele style and so on. Yan Zhenqing (709-785) pioneered Yan Ti. Yan Kai uses a pen to hide his head and protect his tail. His lines are rich, his words are dignified and magnificent, and his composition is simple and rich, which pushes the beauty of regular script to the extreme. Its overall style is rigorous, generous and vigorous.
4. It has a great impact on society. At present, the physical structure of Chinese characters is basically born out of Liu Ti and Wei Bei, and it is popular in the northern areas of Wei, Jin, Southern and Northern Dynasties. The calligraphy works preserved in this period are mainly on a large number of inscriptions, and most of them are from the Northern Wei Dynasty, so they are called "Wei Bei". Wei Bei is often used, and the horizontal shoulders are round inside and outside, giving people a rough and unrestrained feeling.
