The Regular Script (often called standard script or simply kǎishū) is one of the last major calligraphic styles to develop, emerging between the Chinese Han dynasty and Three Kingdoms period, gaining dominance in the Southern and Northern Dynasties, and maturing in the Tang Dynasty. It emerged from a neatly written, early period semi-cursive form of clerical script. As the name suggests, the Regular Script is "regular", with each of the strokes placed slowly and carefully, the brush lifted from the paper and all the strokes distinct from each other. The Regular Script is also the easiest to recognize and read, as it is the script in which most beginners learn to write East Asian scripts.
The Regular Script is usually studied first to give students a feel for correct placement and balance, as well as to provide a proper base for the other, more flowing styles.
