Travelers Among Mountains and Streams (溪山行旅图) is universally regarded as the greatest masterpiece of Northern Song Dynasty landscape painting. Attributed to the hermit-painter Fan Kuan, this monumental work is a definitive expression of the "monumental landscape" style, embodying the Neo-Confucian search for cosmic order and the Taoist reverence for nature's overwhelming power.

Fan Kuan was a reclusive master who lived in the Qin Mountains to study nature firsthand. He famously stated that "it is better to learn from nature than from men," marking a shift from stylistic imitation to direct observation. His personality—unassuming, broad-minded, and severe—is reflected in the rugged grandeur and unshakeable stability of his mountains.

The painting utilizes a three-stage vertical composition. The foreground features rocky outcrops and a bridge with a pack of travelers and mules, providing a human scale. The middle ground is separated by a misty void, which serves as a visual "breath." The background is dominated by a colossal, sheer cliff that occupies two-thirds of the scroll, representing the eternal majesty of the universe.

To define the weathered, rocky surface of the mountain, Fan Kuan developed the "Raindrop" stroke (Yu Dian Cun)—thousands of tiny, vertical, staccato dabs of ink. This technique gives the peaks a palpable texture and a sense of geological weight. The dark, layered ink washes create a luminous depth, while the "iron-wire" lines of the gnarled trees provide a structural skeleton to the composition.

The painting is a visual manifestation of Neo-Confucianism, which sought to find the Li (Universal Principle) in the physical world. The mountain represents the ruler or the supreme truth, while the travelers signify the humility of human existence. It invites the viewer to practice "Woyou" (wandering while lying down)—a spiritual journey into the mountain without leaving one's home.

For centuries, the painting was anonymous until 1958, when the signature of "Fan Kuan" was discovered hidden among the leaves of the brushwood in the lower right corner. This discovery confirmed the work as one of the few authentic monuments of 11th-century Chinese art. Today, it is the centerpiece of the National Palace Museum collection.
