Chinese Cursive: Xingshu and Caoshu Explained

In the year 353 CE, a Chinese official named Wang Xizhi sat down at a gathering of poets near a winding stream, had a bit too much wine, and wrote a 324-character preface for their poetry collection. That document, the Lanteting Xu (Preface to the Poems Composed at the Orchid Pavilion), is still considered the single greatest work of calligraphy in Chinese history -- and it's written in xingshu, the 'running script' that sits between careful regular script and wild cursive. Today we're learning the two scripts that let Chinese calligraphers write with speed and personal expression: xingshu (running script) and caoshu (grass script/cursive script).

- How xingshu (running script) differs from kaishu (standard/regular script) - What makes caoshu (cursive/grass script) the most abstract and fastest Chinese script - The stroke techniques that define each style: connection, simplification, and momentum - How to practice basic xingshu strokes using correct brush pressure and rhythm

Xingshu (行書, literally 'walking script') developed during the Han and Jin dynasties as a faster, more fluid alternative to kaishu, the formal block-style script used for official documents. In xingshu, strokes that would be fully separated in regular script begin to connect -- a calligrapher lifts the brush less often, letting ink trail between strokes in thin connecting lines called 'silk threads' (si xian). Wang Xizhi's Lantingji Xu is the benchmark for xingshu precisely because it balances speed with legibility: every character is still readable, but the brushwork has visible rhythm, varying pressure, and natural, almost accidental-looking imperfections -- ink blots and corrected characters -- that calligraphers for the next 1,600 years have studied and copied stroke by stroke.

Caoshu (草書) pushes speed and abstraction much further than xingshu. Multiple strokes -- sometimes an entire character -- are compressed into a single continuous brush motion. Characters that take 8-12 discrete strokes in kaishu might be rendered in caoshu with just 2 or 3 sweeping motions, and their shapes become so simplified that reading caoshu fluently requires specific training separate from reading regular Chinese text. There are actually two main forms: zhangcao (an early, more structured cursive from the Han dynasty, where characters still stay somewhat separate) and jincao ('modern cursive,' developed by masters like Zhang Zhi and later perfected by Zhang Xu in the Tang dynasty, where entire columns of characters can flow together in one unbroken gesture). Zhang Xu was nicknamed 'Crazy Zhang' because he reportedly dipped his own hair in ink to paint giant cursive characters after drinking -- a story that shows how caoshu became linked with emotional, almost performative expression.

Both scripts depend on controlling brush pressure through a stroke, not just at the start and end. In xingshu, a calligrapher presses down (pressing the tip to widen the line) then lifts (reducing pressure to taper it) within a single stroke, creating the visual 'weight' that makes running script feel alive rather than mechanical. In caoshu, this pressure control has to happen even faster, often while the brush is already moving toward the next stroke. Practicing the transitional connecting strokes -- called 'silk thread' lines because they're thin, unbroken, and often barely visible -- is usually where students spend the most time, because rushing them produces messy blots rather than intentional flow.
