"Style" is of guiding significance to the artistic form and style of calligraphy in terms of system and basic tendency. In the process of calligraphy creation, it is embodied in "layout" and "expected font", which is the blueprint for calligraphers to arrange and conceive the whole creation. For the viewer, it is the style and formal norms observed from the overall artistic image. The guiding significance of "style" can be divided into three levels: it may come from the traditional norms of various calligraphy styles, it may come from the provisions of calligraphers' inherent styles, and it may also come from some special ideas about layout and font when Linchi wrote books.
The "potential" in calligraphy can be regarded as an artistic effect in the process of pen and ink running. As Yu Shinan pointed out, the trend of calligraphy is as impermanent as fighting and as uncertain as the shape of fire and water. A careful understanding of the "potential" mentioned by Zhang Huaiguan and others is flexible and changeable, and its production process is also different: some are arranged in anticipation, that is, out of "intention"; And "yet I feel the harmonious heart-beat of the Sacred Unicorn". The relationship between "potential" and "body" is the most direct. However, as far as a mature calligrapher is concerned, although "heart and hand change" is flexible, it is always potentially related to his skill, style, artistic pursuit and other "body"-related factors.
