Kuncan (1612–1673), also known by his monastic name Shi Xi, was a towering figure among the "Four Monk Masters" of the early Qing Dynasty. His work, "Chui Gan Tu" (Angling in Solitude), is a quintessential representation of his unique artistic and spiritual path. As a Ming loyalist who entered the Buddhist monkhood after the fall of his dynasty, Kuncan used the theme of reclusion—embodied here by the solitary act of fishing—to express his existential solitude and his rejection of the mundane political world.

The aesthetic essence of "Chui Gan Tu" is defined by Kuncan’s celebrated "Cangmang" style. In contrast to the sparse, crystalline landscapes of his contemporary Hong Ren, Kuncan’s vision of nature is dense, textured, and vigorous. In this painting, the mountain cliffs and overhanging trees are rendered with a wild, unrefined energy that captures the raw vitality of the wilderness. The landscape feels "thick" and "heavy," reflecting a profound sincerity and a visceral connection to the earth.

In terms of artistic technique, Kuncan was a master of the dry-brush (ganbi) and layered ink (jimo) methods. In "Chui Gan Tu," he utilized coarse texture strokes (Cun-fa) and intricate "rubbing" brushwork to build up the rugged surfaces of the rocks and the gnarled trunks of the trees. By repeatedly applying layers of ink, he achieved a remarkable sense of three-dimensional volume and tactile depth. His brushwork appears "scruffy" or "blurred" at first glance, but it possesses a sophisticated structure that creates a powerful interplay of light and shadow.

The iconography of the solitary angler (chui gan) is central to the painting's meaning. Nestled at the base of a towering, mist-shrouded cliff, the small figure with a fishing rod represents the literati ideal of "leisurely wandering" (Xiao Yao). In Chan Buddhist and Taoist philosophy, the fisherman is a symbol of detachment—someone who is in the world but not of it. For Kuncan, this figure is a self-portrait of the soul, a reclusive monk seeking spiritual asylum and inner peace amidst the "layered ravines" of a changing era.

Historically and philosophically, "Chui Gan Tu" stands as a landmark of Individualist painting in 17th-century China. It demonstrates how Kuncan bridged the gap between Yuan Dynasty traditions (specifically the influence of Wang Meng) and a more subjective expression of personal identity. His "thick and heavy" brushwork had a profound influence on modern landscape masters, most notably Huang Binhong. Today, the painting is revered for its psychological depth, embodying the quiet resilience and spiritual height of a man who found heavenly harmony in the rugged solitude of the mountains.
