Bark pile painting uses the natural texture of the bark, through simple processing, and then carefully piled, colored, and rendered. It is not only a craft art, but also a landscape painting carefully created by the author. It is majestic and rough, simple and elegant, with a strong sense of three-dimensionality and unique style. It cannot be copied because the author's creative ideas and bark texture are different. It is best for expressing the majestic and beautiful natural scenery of Wujiang Gorge. It is a precious tourist souvenir that tourists are vying to collect.
