Calligraphy is not an art. Calligraphy and art belong to the category of art and are equal as twin sisters. Calligraphy and painting are two extremely important art forms in China's ancient and modern art categories. They are like a pair of twin sisters with the same root and homology, showing elegant charm on the big stage of China culture and art, so there has been a saying that "calligraphy and painting are homologous" since ancient times. It is found that the important aesthetic links of painting art are related to the aesthetic links of calligraphy art.
