Running Script (Xing Shu), a calligraphy style that is semi-regular and semi-cursive, originated in the Han Dynasty (206B.C.-220A.D.), and became mature during the Wei (220-265) and Jin (265-420) dynasties. It simplifies the strokes of Regular Script (Kai Shu), transforms the patterns of Regular Script, and loosens the structure of Regular Script, thus being more applicable and practical to daily life compared to Regular Script and Cursive Script (Cao Shu). The "Preface to the Orchid Pavilion," in running script on paper, is a calligraphic work by Wang Xizhi (303-361), now in the collection of Beijing Palace Museum. It is said that Wang invited friends to gather at the Orchid Pavilion on the outskirts of Shanyin in Kuaiji (present-day Shaoxing, Zhejiang Province), where they drank wine and composed poems for an anthology, to which Wang wrote the preface. The calligraphy features vigorous strokes, an unconstrained structure, and a graceful style, vividly representing the new form initiated by Wang Xizhi. It produced a profound influence upon Chinese calligraphy in the following generations.
