When using brushes to paint gongbi, there are specific types for contouring and colouring. There are four types of brushes for
contouring; Hong Mao (red hairs), are used to draw thick strokes mainly for
landscape and background visuals. Yi Wen is used for longer lines to paint clothing, for example. Ye Jing brushes are used to contour flowers and bedsheets. Xie Zhua is the finest contour brush used to paint strokes of dragonflies and specific detail in the painting. There are three sizes of brushes used to colour the surface of the painting: Da Bai Yun (large white cloud), Zhong Bai Yun (average white cloud) and Xiao Bai Yun (small white cloud). Rough drafts are usually drawn on
Xuan paper. If there is only one draft, a special type of paper called
Xuan paper is used. There are two different kinds of Xuan paper. One is called Shu Xuan paper (cooked rice paper). It is usually used for Gongbi. Another kind is Sheng Xuan paper (raw rice paper). It is usually used for Xieyi ( 'sketch-thought style painting'). The soft paper is able to absorb water well, best used for
Chinese painting and
calligraphy. Silk can also be used, which is sized as well. ==Process of the craft==
