The relationship between Chinese painting and calligraphy, on the one hand, is the same in their tool materials, especially the writing brush, which has the same method of writing and carrying pens, on the other hand, it is about the requirement of using pens, which is the basic norm and concept based on the center since ancient times and has been upheld by calligraphy and Chinese painting. Therefore, in the Tang Dynasty, Zhang Yanyuan said that "the names of calligraphy and painting are different but the body is the same". Calligraphy and painting have been interlinked since ancient times, and the ancients said that "calligraphy and painting are homologous". In Shi Tao's words, "it has two ends and its work is integrated." There are many people in history who have been painting and calligraphy for two sessions. There are people who paint with books, people who paint with books, people who are famous for their paintings, and people who are famous for their names, so there are painters' calligraphy and calligraphers' paintings. When a painter writes a book, he always puts his own pen and ink into the book, so the book is picturesque. Calligraphers are good at applying the brushwork charm of calligraphy to paintings when painting, so paintings are elegant. Whether it is a painter's book or a calligrapher's painting, high-level law and reason are interlinked.
In the history of calligraphy, painter's calligraphy is also a branch that cannot be ignored. To put it simply, from Mi Fei in the Song Dynasty, Zhao Mengfu in the Yuan Dynasty, Shen Zhou, Wen Zhiming and Dong Qichang in the Ming Dynasty to Shi Tao, Ba Da, Zheng Banqiao, Jin Nong and Zhao Qianzhi in the Qing Dynasty, in addition to their achievements in painting, they also had special attainments in calligraphy art, and their calligraphy was unique at that time. So that in the 20th century, Wu Changshuo, Qi Baishi, Huang, Pan Tianshou and others were also famous calligraphers! Their achievements in calligraphy are clearly reflected in painting, which shows that calligraphy has laid a solid foundation for their achievements in painting. On the contrary, their calligraphy benefits from the inspiration in the formal beauty of painting, which makes calligraphy show its charm different from that of pure calligraphers.
