Chinese calligraphy is an art practice that uses pen, ink, paper and other tools as its main materials. It not only completes the practical function of information exchange, but also integrates people's thinking about nature, society and life with unique modeling symbols and pen and ink rhythm, thus showing the unique way of thinking, personality spirit and temperament of the Chinese people. Chinese calligraphy has developed along with the creation and evolution of Chinese characters. After more than 3,000 years, it has become a representative symbol of Chinese culture.
