Chinese calligraphy is an ancient art of writing Chinese characters. It has evolved from oracle bone inscriptions, stone drum inscriptions and gold inscriptions (Zhong Dingwen) to large seal characters, small seal characters and official script, and to cursive script, regular script and running script finalized in the Eastern Han, Wei and Jin Dynasties. Calligraphy has always exuded artistic charm. Calligraphy is a unique traditional art in China. Chinese characters were created by the working people. They began to record events with pictures. After thousands of years of development, they have evolved into today's characters. Calligraphy came into being because their ancestors invented writing with a brush. From ancient to modern times, Chinese characters have been mainly written with brush. As for other writing forms, such as hard pen and finger calligraphy, the writing law is not completely different from that of brush characters, but basically interlinked. Calligraphy refers to writing according to the characteristics and meaning of characters, with its calligraphy style, structure and composition, so as to make it an aesthetic work of art.
