in Chinese shuǐ-mò (水墨, "water and ink") also loosely termed watercolor or brush painting, and also known as "literati painting", as it was one of the "four arts" of the Chinese Scholar-official class. In theory this was an art practiced by gentlemen, a distinction that begins to be made in writings on art from the Song dynasty, though in fact the careers of leading exponents could benefit considerably. This style is also referred to as "xieyi" (寫意) or freehand style.
