East Asian calligraphy in the context of Ink wash painting

Strokes (simplified Chinese: 笔画; traditional Chinese: 筆畫; pinyin: bǐhuà) are the smallest structural units making up written Chinese characters. In the act of writing, a stroke is defined as a movement of a writing instrument on a writing material surface, or the trace left on the surface from a discrete application of the writing implement. The modern sense of discretized strokes first came into being with the clerical script during the Han dynasty. In the regular script that emerged during the Tang dynasty—the most recent major style, highly studied for its aesthetics in East Asian calligraphy—individual strokes are discrete and highly regularized. By contrast, the ancient seal script has line terminals within characters that are often unclear, making them non-trivial to count.

Study and classification of strokes is useful for understanding Chinese character calligraphy, ensuring character legibility, identifying fundamental components of radicals, and implementing support for the writing system on computers.

Ink wash painting (simplified Chinese: 水墨画; traditional Chinese: 水墨畫; pinyin: shuǐmòhuà) is a type of Chinese ink brush painting which uses washes of black ink, such as that used in East Asian calligraphy, in different concentrations. It emerged during the Tang dynasty of China (618–907), and overturned earlier, more realistic techniques. It is typically monochrome, using only shades of black, with a great emphasis on virtuoso brushwork and conveying the perceived "spirit" or "essence" of a subject over direct imitation. Ink wash painting flourished from the Song dynasty in China (960–1279) onwards, as well as in Japan after it was introduced by Zen Buddhist monks in the 14th century. Some Western scholars divide Chinese painting (including ink wash painting) into three periods: times of representation, times of expression, and historical Oriental art. Chinese scholars have their own views which may be different; they believe that contemporary Chinese ink wash paintings are the pluralistic continuation of multiple historical traditions.

In China, Japan and, to a lesser extent, Korea, ink wash painting formed a distinct stylistic tradition with a different set of artists working in it than from those in other types of painting. In China especially it was a gentlemanly occupation associated with poetry and calligraphy. It was often produced by the scholar-official or literati class, ideally illustrating their own poetry and producing the paintings as gifts for friends or patrons, rather than painting for payment.In practice a talented painter often had an advantage in climbing the bureaucratic ladder. In Korea, painters were less segregated, and more willing to paint in two techniques, such as mixing areas of colour with monochrome ink, for example in painting the faces of figures.
