An extremely attentive work is made under inattentiveness. He wins a good painting by surprise skill. His composing the painting is different from "big to small". He sets the composition first, and then delineate the contour one layer after another with his old method of "small to big". Each line produces another line so as to compose a good picture. The colors are either thick or thin. At the beginning there is no specific idea of composition.

他作画技法骨法用笔，注重点线面，强调「写」而反对「描」，做到笔的轻重疾徐，墨的乾湿浓淡，线条大小粗细、虚实及用笔多角度，方圆之间酣唱淋漓，力透纸背，充满韵律感和节奏感，故能表现密体山水，细笔中笔笔写到，千笔万点溶为大整体；近视精微之，远视只见大整体；近观如入山中密林，远观见山峦之气势。
