Yandang Mountain is a strange and beautiful mountain in the world, but it has never been mentioned in the geographical atlas since ancient times. During the Xiang Fu period in the Song Dynasty, Yuqing Palace was built, and it was only when the mountains were cut. At this time, it doesn't even have the name of the mountain. According to books in the western regions, there lived a Lohan named Luo Nuoju at the Dragon Bridge of Furong Peak in Yandang Mountain on the southeast coast of China. In the Tang Dynasty, a monk named Guan Xiu wrote Nuoju Rozan, and there was a poem "Wild geese are flowing clouds, and the dragon feast is rainy".

There is Furong Peak in the south of this mountain, and Furong Hill is under the peak. Looking ahead, you can overlook the sea. However, people at that time did not know where Yandang and Longqiu were. Later, people began to see the mountain because of logging. There is a big pool on the top of the mountain, which is regarded as the legendary wild goose swing; There are two pools at the foot of the mountain, thinking they are big and small dragons. As for the gorge and the peak, they are all named after Guan Xiu's poems. When Xie Lingyun, a poet of the Song Dynasty in the Southern Dynasties, was appointed as the magistrate of Yongjia, he almost traveled all over the landscape of Yongjia, but he didn't talk about this Yandang Mountain because there was no such name at that time.

I observe these peaks of Yandang Mountain, which are steep, high, straight, steep and strange. They stand up, about thousands of feet high, with high cliffs and huge valleys, unlike other mountains. Many of its peaks are contained in the surrounding valleys. Looking at these peaks from outside to inside, you can't see anything; Only when you walk into the valley can you see them towering into the sky. The cause of formation should be the result of being washed away by the flood water in the valley. All the sand was washed away, leaving only these upright boulders. As for the dragons, water curtains, the first moon valley and so on, they are all caves washed by water.

Seen from below, these peaks are towering rock cliffs; Seen from above, the peaks in the valley are as high as the surrounding mountains, even lower than the ground of the surrounding mountains. Where streams and valleys in the world are washed away by water, there are towering soil layers and rocks like shrines, all of which belong to this situation and have the same causes. Today, in the mountains and streams west of Shaanxi, the vertical soil layer often reaches hundreds of feet and stands tall, which can be regarded as the similar shape of the smaller Yandang Mountain, but here is loess and there is stone.

Because many peaks of Yandang Mountain are not standing on the ground, but covered by deep valleys and old forests, the ancients did not see them, so it is not surprising that Xie Lingyun has never been there.

Second, the original text: from? Northern Song Dynasty? Shen Kuo's "Meng Qian Bi Tan"

Yandang Mountain in Wenzhou is a wonderful place in the world. However, since ancient times, there has been no writing. Among the auspicious symbols, Yuqing Palace was built and the mountain was cut down to make materials. Only some people have seen it, but it is not famous yet. According to the Records of the Western Regions, Alao 'nao lived in the Records of the Wild Goose in the Sinian, Furong Peak and the southeast of Dragon Ball. Guan Xiu, a Tang priest, wrote a poem called "Wild geese shake the clouds, and the dragon tyrants feast with rain". There is Furong Peak in the south of this mountain, and there is Furong Hill under the peak, which overlooks the sea, but I don't know where Yandang and Longqiao are. I saw this mountain after logging.

There is a big pool at the top of the mountain, which is said to be a wild goose swing. There are two pools of water under it, which are thought to be dragons. There are also those who have crossed the gorge and returned to the peak, all named after Guan Xiu's poems. Xie Lingyun has been guarding Yongjia and traveled all over the landscape of Yongjia, but he didn't talk about this mountain alone. Gai didn't have the name of Wild Goose Swing at that time.

Look at the peaks of Yandang Mountain. They are all steep and steep. Climbing to thousands of feet, the huge valleys on the cliffs are all wrapped in valleys, unlike other mountains. From the outside of the ridge, nothing can be seen, but in the valley, it is new and dry. The reason is that the valley is flooded, the sand is gone, and only the boulder stands. Such as big and small dragons, water curtain, early moon valley, etc. , are all holes made by water. From the bottom, there are high cliffs; Seen from above, it is suitable for the ground. Even the top of the mountain is lower than the top of the mountain. There is a niche for planting soil and this kind of ear in the gully where water is cut in the world. In today's Chengdu-Gaoshan, Shaanxi-Dajianhe, the earth stands and moves a hundred feet. It stands tall, but it is also concrete and small, but this soil is a stone ear.

Not out of the ground, but covered by the deep valley Lin Mang, so the ancients didn't see it, and the spiritual luck couldn't reach it, which was unreasonable.

Extended data

I. Introduction to the work:

Meng Qian Bi Tan is a comprehensive note work written by Shen Kuo (1031-1095), a scientist and politician in the Northern Song Dynasty, which involves natural science, technology and social and historical phenomena in ancient China. This book is also very valuable in the world, and it was appraised as "a milestone in the history of science in China" by the British historian Joseph Needham.

According to the oldest extant Dade block print, Meng Qian Bi Tan is divided into 30 volumes, including 26 volumes of Bi Tan, 3 volumes of Bu Bi Tan and Continued Bi Tan 1 volume. There are 17 items and 609 articles in the book. The content involves astronomy, mathematics, physics, chemistry, biology and other disciplines, which is of great value. The natural science part of the book summarizes the scientific achievements of China in ancient times, especially in the Northern Song Dynasty. In terms of social history, it exposed the decay of the ruling clique in the Northern Song Dynasty, and recorded in detail the military interests of the northwest and the north, the evolution of the etiquette system, and the drawbacks of the old tax system.

Meng Qian Bi Tan was written at the end of 1 1 century, which is generally considered to be between 1086 and 1093. The author said that his creation "is not a person's interest", and the starting point is "the shade in the mountains is intended to talk." The title of Meng Qian Bitan is the name of "Meng Xi Park" where Shen Kuo lived in seclusion in Runzhou (now Zhenjiang) in his later years. Books, including Zuben, have long been lost in the Song Dynasty. The oldest version that can be seen now is 1305 (the ninth year of Yuan Dade), which is now in the National Library of China. Yuan Dade's engraving is rare, with clear circulation and orderly version. After several dynasties, it was easily collected by its owner and bought back in Hongkong on 1965 under the auspices of Zhou Enlai.
