There is a saying that calligraphy and painting are of the same origin, which means that China's paintings are closely related to China's calligraphy, and their emergence and development complement each other. In the use of pen and ink, there is the same rule. The use of calligraphy is the language of Chinese painting modeling. It is difficult to describe Chinese painting without the help of calligraphy. Therefore, Chinese painting itself has a strong interest in calligraphy. The lines and Mo Yun of Chinese painting reveal the beauty of abstraction and its independent aesthetic value everywhere.
The "source" of the homology of painting and calligraphy is not only the surface expression and the homology of pen and ink application, but also the essence of painting and calligraphy art, which has the homology of essence and artistic conception.
