‘Cǎoshū’ (cursive script) is one of the major styles of Chinese calligraphy, characterized by highly simplified, fluid, and interconnected strokes. The character 草 (cǎo) literally means 'grass' but here conveys the sense of 'rough', 'hasty', or 'unrestrained' — reflecting the swift, spontaneous writing style. The character 书 (shū) means 'writing' or 'script'. Together, 草书 refers to a dynamic, expressive form of handwriting developed for speed and artistic freedom, historically used by scholars and artists for personal notes or creative expression.

Unlike standard script (楷书), cǎoshū often omits or merges strokes dramatically, making it difficult for beginners to read. It requires years of practice to master both writing and recognizing its forms. While rarely used in daily communication today, cǎoshū remains central to Chinese art education, exhibitions, and cultural appreciation — valued for its rhythm, energy, and individuality.
