Running script, or xingshu, occupies a unique space in the world of Chinese calligraphy, bridging the gap between the formal precision of regular script and the unrestrained freedom of cursive script. This essay will delve into the foundational aspects of xingshu, emphasizing its defining characteristic: fluidity. Unlike kaishu which emphasizes clear structure and deliberate strokes, xingshu is characterized by its dynamic energy, where strokes often flow smoothly and continuously from one to another. The essay will explore the subtle changes in brush speed and pressure that create a sense of movement and rhythm, essential elements that allow xingshu to convey a feeling of effortless grace. This introduction sets the stage for a deep analysis of the script’s techniques and aesthetics.
