What are the five images in calligraphy?

The five images in calligraphy refer to the five fonts of "line, grass, official script, seal script and regular script", which are the basis of traditional calligraphy in China. Running script is developed from official script, which is the standard font of cursive script, and its change is smooth and coherent strokes, which makes the whole text have a certain sense of speed and beauty. Cursive script is a variant of running script, which is characterized by fast strokes, simplicity and fluency, and the combination of complexity and simplicity. It is often used for personalized creation in the art of calligraphy. Lishu used to be an ancient official script in China, which is a kind of writing between seal script and regular script, and is famous for its vigorous brushwork and powerful strokes. Seal script is the characters on ancient seals, which gradually evolved into a calligraphy style, characterized by strong strokes, regular fonts, compact structure and simple and elegant beauty. Regular script, also known as regular script, is a standard font in calligraphy art, with regular font, clear strokes and stable structure. It is a common script for writing on formal occasions. These five fonts are widely used and become the soul and cornerstone of China's calligraphy art.
