Chinese calligraphy is the product of Chinese culture. The art of calligraphy is closely related to the philosophy of Confucianism, Buddhism and Taoism in Chinese culture. In history, calligraphy is basically a great scholar of accumulation learning. They use calligraphy to express their feelings and express their temperament in calligraphy. Therefore, Zhao Zhiqian, a famous calligrapher, painter and seal engraver in the Qing Dynasty, said that there are two kinds of people who can write well: “three-year-old child” and “great scholar of accumulation learning”. The former lies in the true nature of mind, while the latter lies in the massiness of connotation.
