Sword Severing the Clouds

Sword Severing the Clouds

Sword Severing the Clouds, located in Tai'an City, Shandong Province, features a massive upright rock above Zengfu Temple that resembles a sword piercing the sky, inscribed with the words "Sword Severing the Clouds." This sharp blade was neither a gift from mountain deities nor the masterpiece of skilled craftsmen.

The rock and surrounding stone are a type of banded amphibole plagioclase gneiss, appearing greenish-gray and mainly composed of minerals such as plagioclase, quartz, and amphibole. Due to the well-developed gneissic foliation, the rock is prone to weathering and erosion. Coupled with two sets of vertical joints in different directions within the rock, prolonged weathering has resulted in the formation of platy rock blocks. Subsequent spherical weathering further smoothed the original edges and corners, gradually shaping this sword-like rock formation.

The gneissic foliation direction is 320 degrees northwest, with an almost vertical dip, while the gneissic foliation of the amphibole plagioclase gneiss in Sword Severing the Clouds runs at 270 or 90 degrees, oriented east-west, also nearly vertical. There is a 50-degree angle between the two foliation directions, indicating that this rock block had previously toppled before being re-erected by people. The inscription “Re-erected in the 16th Year of the Republic of China” confirms this. Therefore, the Sword Severing the Clouds we see today is not the original outcrop of the amphibole plagioclase gneiss.

As for the legend that Sword Severing the Clouds can “cut clouds and summon rain,” though it includes mythologizing and exaggeration, there is actually some scientific reasoning behind it. The terrain around Sword Severing the Clouds forms a narrow, concave zone—steep in the north, gentle in the south, with a precipitous slope above and a secluded valley below.

Sword Severing the Clouds is situated right at the valley mouth. On overcast days, the clouds and mist gathered in the valley below rise upward along the valley floor. When they reach the valley opening where the sword stands, they meet the cold air descending from the mountain. The collision causes the moisture to condense into fine rain, creating the phenomenon of the clouds dissipating while a light drizzle begins to fall. Thus, it becomes clear that the changing cloud and rain patterns here are not due to any magical power of the sword, but rather a natural meteorological phenomenon caused by the area’s unique landform and atmospheric conditions. The way the ancients placed this extraordinary rock so perfectly and bestowed upon it a legendary name makes it one of the marvels of Mount Tai.

Sword Severing the Clouds is located south of the Yunbu Bridge on Mount Tai. The so-called “sword” is merely an elongated mountain rock. But crafted by nature’s artistry and situated in a perfect spot, it truly seems to “sever the clouds.”

Legend has it that long ago, a group of people were gathering herbs in the mountains. The rejuvenating polygonum multiflorum, the panacea lingzhi mushroom, the life-restoring thousand-year-old poria cocos, and the tonifying wild yam of Mount Tai that invigorates the body and enhances agility all drew them in. They focused intently on their herb-gathering, oblivious to the rugged mountain paths and the ever-changing skies. When they reached the base of Sword Severing the Clouds and began climbing the cliffs, dark clouds suddenly churned across the sky, shrouding the entire mountain. Visibility dropped to zero, and the treacherous terrain filled everyone with panic. They warned and supported one another, striving to escape the peril and return home safely.

At the height of the crisis, a young man stepped forward. He urged everyone to stay calm and look after one another, waiting in place. Then he leapt onto a large boulder on the slope, let out a mighty roar that shook the earth, and swung his arms with such force that wind seemed to whip from them. As he continued to wave his arms, the vast sea of clouds and swirling mist suddenly scattered and dissipated. The sky turned a brilliant blue, the sun shone brightly overhead, and a gentle breeze blew. Seeing this, the crowd broke into spontaneous cheers.

But when the people, overjoyed, looked for the brave young man, he was nowhere to be found. They searched high and low, calling his name, combing through the mountains and valleys, yet there was no sign of him. With heavy hearts, they returned to the spot where the youth had driven away the clouds and mist.

Then a wise person suddenly noticed that the tall, upright rock on the cliff face resembled the form of the young man. Following his guidance, everyone stood solemnly before the rock, paying tribute and expressing their remembrance.

Since then, the churning clouds and rolling mists have never returned to the area. Any clouds or mists that rise or descend naturally part ways here. To commemorate the brave youth who cleared the clouds and dispersed the fog, people named the standing stone “Sword Severing the Clouds.” Now, when visitors come here, they too stand in respectful awe, honoring this heroic and noble young figure.
