Linwu Cave

Linwu Cave

Linwu Cave is located in the northeastern part of Xi Shan Island in Taihu Lake, Suzhou, to the west of Linwu Mountain. According to Taoist classics such as the *Yunji Qiqian*, there are ten great grotto-heavens, thirty-six lesser grotto-heavens, and seventy-two blessed lands in the world, all inhabited by immortals. Linwu Cave is the Ninth Grotto-Heaven, also known as the "Left Divine Secluded Void Heaven" and nicknamed the "Celestial Queen’s Secondary Palace." Legend has it that in ancient times, a dragon lived inside Linwu Cave, giving the cave a serpentine shape and earning it the name "Dragon Cave." Linwu Mountain is also called Dragon Cave Mountain.

The Linwu Cave scenic area covers 18 hectares and is a limestone underground hall-type karst cave. The cavern is as spacious as a grand building, with standing rocks forming a forest and the ceiling flat like a house roof—hence the name Linwu (Forest House). The paths inside the cave are smooth and the waters calm, making one feel as though strolling through a leisurely courtyard. Looking up, one sees stalactites hanging upside down, a masterpiece of nature. The cave features interconnected chambers—some narrow, some wide, both deep and winding—with an unfathomable mystery and bewildering allure. The cave includes various rock formations such as stone chambers, dragon beds, silver rooms, stone bells, stone drums, golden courts, jade pillars, white ganoderma, golden sand, dragon basins, the Gate of Transcendence, stone swallows, hidden springs, and milk springs.

Exiting the cave and climbing the mountain, one can watch at dusk as birds return to their nests, fishing boats cast faint shadows, and wisps of cooking smoke rise gently—one of the ancient Ten Scenic Spots of Xi Shan, known as "Linwu Evening Mist." At the mountaintop stands the "Jiafu Pavilion," 24 meters high. From here, one can enjoy the splendid view of the plum blossom garden. The 3,000-acre sea of plum blossoms is a breathtaking sight. The "Linwu Plum Sea" has become the largest base in China for plum blossom appreciation and related cultural activities. The "Suzhou Taihu Xi Shan Plum Blossom Festival," held annually from late February to early March, takes place here.

The characteristics of Linwu Cave can be summarized in six "manys."

First, there are many stone sprouts: Stone sprouts are protruding bedrock on the cave floor. They form a unique stone forest, unlike any other in karst caves across the country.

Second, there are many stone trenches: Stone trenches are grooves on the cave floor, resembling trenches. They are deeper than they are wide. These trenches can be straight or curved, long or short, varying in depth and ever-changing. The *Five Elements* text refers to stone trenches as earth meridians, connecting underground rivers with a continuous flow that never dries up. The mirror-like water reflects the steep cliffs, creating a uniquely charming scene.

Third, there are many pictographic rocks: On the cave floor, there are many cavities open at the top, called pits or mortars. A larger pit connected to a smaller tunnel resembles a stove—with the upper part like a stove surface and the lower part like a stove chamber. Taoism mythologized it as the "Immortal’s Stove."

Stone platforms are horizontal bedrock protrusions on the cave walls, which Taoism calls the "Immortal’s Bed." Liu Jue, Minister of Personnel in the late Northern Song Dynasty, wrote a poem about spiritually traveling on the stone bed after hearing tales from Taoist priests: *"Fresh nectar fills the gourd, / In the deep grotto-heaven, I roam free. / I sing the Purple Ganoderma tune of the recluse, / Harmonizing with the immortal’s jade flute. / Moonlight on the stone bed, clouds never cease; / Wind rustles the leaves, all fluttering. / Peaches suddenly bloom like brocade, / I cross the Jade Pool, wine still not faded."*

Stone niches are small caves within the cave walls, shaped like small shrines for Buddha statues. Taoism calls them "divine niches."

Sky gutters are curved grooves embedded in the middle of the cave ceiling. Their horizontal width is greater than their vertical height. The sky gutter is over 20 meters long, with undulating and varied stone patterns resembling a dragon—Taoism calls it the "Divine Dragon."

The more carefully and diversely one observes these stones, the more beauty they reveal. As the saying goes, imagination, imagination—the more you imagine, the more it resembles. In the cave, there are endless rock formations resembling frogs, pigs, eagles, fish, sheep, and more.

Fourth, there is abundant water: Linwu Cave is essentially a water cave, with a daily outflow of about 300 cubic meters. Water must be drained daily, or the cave cannot be visited. There are countless invisible springs inside, and two visible ones—Milk Spring and Purple Hidden Spring. Milk Spring’s water is as white as milk, commonly called "Grandma Spring." It is abundant in the rainy season, flowing fiercely like a waterfall, and sparse in the dry season, flowing gently like a thin thread. Purple Hidden Spring has a steady flow year-round. Ming Dynasty Grand Secretary Wang Ao wrote in his poem *Purple Hidden Spring*: *"At the cave mouth lies a deep well, / Celestial elixir fills the void. / I bring a jar here, / Hoping to connect with the immortal spring."*

Fifth, there are many reflections: Water flows through the cave, bringing it to life. The emerald water casts reflections, blending reality and illusion in delightful ways.

Sixth, there are many bridges: There are four flat bridges and two stepping stones inside the cave. Beneath the bridges are natural gullies, which probes have found to be over two zhang (about six meters) deep in silt. For safety reasons, the silt was not fully removed, so now visitors only get the feeling of being near the water.

Linwu Cave is an exquisitely constructed underground palace, a vast yet intricate artistic treasure trove. Its formation depends on three basic conditions.

First is limestone.

Second, there are many fractures under Linwu Mountain, providing channels for groundwater flow and surface water infiltration. The cave’s chamber runs roughly east-west, a result of water eroding the limestone along nearly east-west fractures.

Third, Linwu Mountain is located in a water-rich area. Two hundred million years ago, this was the sea; later, the shoreline shifted eastward, and this became Taihu Lake.

Linwu Mountain is a mountain with caves, caves within mountains, and caves within caves—large caves housing smaller ones, all interconnected.

Linwu Cave offers a whole different world inside compared to the vast openness outside. In winter, while it’s freezing outside, the cave remains warm as spring; in summer, while it’s scorching outside, the cave stays cool and moist. Truly a pleasant climate year-round. With its constant temperature and spectacular scenery, Linwu Cave has been praised by ancients as a heavenly paradise on earth.
