To build a viewpoint is an act of reshaping the landscape. In 1908, Heilongjiang Governor Zhou Shumo desired a place to experience the beauty of the local waters. He ordered workers to dig trenches, drawing the currents of the Nen River inland, and piled the excavated earth to form an artificial hill. At its summit, he placed a thatched structure named the Weiyu, or "Before the Rain," Pavilion.

That fragile shelter eventually gave way to permanence. In 1930, architects rebuilt the pavilion as a 25-meter-high brick-and-wood tower. They gave the structure a flattened footprint of 220 square meters, stretching wide across the north-south axis while remaining narrow from east to west. This geometry maximizes the interior vantage points, directing the viewer's eye outward toward the river bank.

Mid-century renovations anchored the building more firmly to its manufactured peak. In 1950 and again in 1979, workers installed heavy stone steps, retaining walls, and internal screens. These additions gave the structure a heavier, grounded presence. The pavilion evolved from a temporary viewing platform into a permanent, dominant fixture on the east bank of Longsha Park's Labor Lake.

The high vantage point attracted successive generations of political figures. In the summer of 1964, state leaders including Zhu De and Dong Biwu climbed the stone stairs to look out over the glittering waters of the Nen River. The sweeping view prompted Zhu De to brush three large characters: Wangjiang Tower, the River-watching Pavilion. Craftsmen carved his calligraphy into a black-and-gold wooden plaque and suspended it beneath the flying eaves. The building assumed this name permanently.

Today, Wangjiang Tower stands as a precise record of shifting eras. The hill beneath it is artificial, built from excavated earth. The water below flows through an engineered channel. Through more than a century of political change and architectural reinforcement, the human impulse driving the site remains consistent: to climb twenty-five meters above the ground, stand beneath the sweeping eaves, and watch the river move.
