What influence does the "leakage mark" in the calligraphy of the title wall have on the sky of landscape painting?

The influence of "leakage marks" of calligraphy on the wall in the sky of landscape painting: enhancing the impact and layering of the picture, the expressive force and appeal of the image, enriching the picture and expressing the texture effect. The house leaks when it rains all night, just like a pen leaks ink. "The house leaks every night, and the pen leaks every night." So "leak marks" are about brushwork and brushwork. It is the magic and charm after nature. It is the embodiment of inspiration, the naturalization of random writing, and the aesthetic effect of watertight calligraphy and unintentional intention. This sentence comes from the dialogue between Yan Zhenqing and Huai Su. The highest realm of calligraphy is still the same, so Chinese paintings with the same origin of calligraphy and painting should take "leakage marks" as a model of pen and ink.
