How is the development of calligraphy?

The font of Chinese characters has experienced a long development process, which can be roughly divided into the following stages:

Oracle Bone Inscriptions period (from14th century BC to 3rd century BC): Oracle Bone Inscriptions was one of the earliest writing forms of Chinese characters, mainly carved on tortoise shells and animal bones. Oracle Bone Inscriptions's brushwork is dull and simple in structure, showing a quaint artistic style.

Bronze inscriptions and seal script period (3rd century BC-3rd century AD): Bronze inscriptions are inscriptions on ancient bronzes and jades, and the structure of fonts and strokes became regular, and various decorative patterns appeared. Seal script is a kind of font in Qin and Han Dynasties, which has a rigorous structure and strong lines, and is an important link in the development of calligraphy in China.

Official script and regular script period (from 3rd century to 8th century): Official script is the font used for official documents in Qin and Han dynasties, which is relatively regular and the strokes appear calm, while regular script is a writing method developed on the basis of official script, with more rounded strokes and more stable structure.

Running script cursive period (8th century to modern times): Running script is a font developed on the basis of regular script, with smooth lines and fast writing speed. Cursive script is a variant of running script, with simpler strokes and more casual forms, showing an abstract artistic style.

In the above stages, each font has its own unique characteristics and styles, reflecting the development of society, culture and art at that time. At the same time, the evolution of these fonts has provided a steady stream of inspiration and materials for the development of China's calligraphy.
