To most of these men, painting was not a professional occupation but only one of the means by which they expressed their intellectual reactions to life and nature in visible symbols. Poetry and illustrative writing were in a sense even more important to them than painting and they made their living as more or less prominent government officials if they did not depend on family wealth. Even if some of them were real masters of ink-painting as well as of calligraphy, they avoided the fame and position of professional artists and became known as “gentleman-painters”. Artistic occupations such as calligraphy and painting were to these men activities to be done during the leisure time from official duties or practical occupations. Nevertheless, the foundation of their technical mastery was in writing, training in calligraphy which allowed them to transmit their thoughts with the same easiness in symbols of nature as in conventional characters. Their art became therefore a very intimate kind of expression, or idea-writing as it was called in later times. The beauty of this art was indeed closely connected to the visible ease with which it was produced, but which after all could not be achieved without intense training and deep thought.
