Overview of the Great Wall in Wan Li

The Great Wall is a great military building in China. It is known as a miracle in the history of ancient human architecture because of its huge scale and arduous project.

The Great Wall was built in the Spring and Autumn Period and the Warring States Period in the 5th century BC. In the 3rd century BC, Qin Shihuang unified China, and after sending 3, troops led by Meng Tian to drive the Xiongnu to the north, the original Great Wall was connected and continued to be built. Since then, it has been continuously maintained and expanded, and it has been built for more than 2, years before and after the mid-17th century.

Badaling

is located in Yanqing County, which is a relatively well-preserved section of the Great Wall in Ming Dynasty. Its Guancheng was built in 155 (the 18th year of Hongzhi in Ming Dynasty), and it is trapezoidal in shape, with two gates in the east and two gates in the west. In the east, it is located in Yongwai Town, and in the west, it is a lock key in the north gate, all of which are masonry structures. The voucher cave is a platform, and two gaps are opened on the north and south sides, connecting the Guancheng wall one after another. The wall of this section is built according to the mountain. The height of the wall is large and firm, the lower part is a stone abutment, and the upper part is built with large city bricks, filled with soil and stones. The top floor is paved with square bricks, and the sealing is dense. The inner side is the Yu wall, and the outer side is the crib wall. There is a crib opening above the crib wall and a shooting hole below it. Where the mountain is steep, a stairway is built, and a fortress-style city platform, an enemy platform or a wall platform is built at the ridge highland, the corner of the city wall or a dangerous place. The wall varies in height and width, with an average height of more than seven meters, and some areas are as high as fourteen meters. The average width of the wall base is six and a half meters, and the top width is more than five meters, which can accommodate five horses running side by side or ten people going hand in hand.

Juyongguan

Juyongguan's name means "migrating to a mediocre place". According to legend, when Qin Shihuang built the Great Wall, he moved the civilian workers who were forced to live here. In the Han Dynasty, it was called Xiguan in the Three Kingdoms period, and changed to Naikuanguan in the Northern Qi Dynasty. In the Tang Dynasty, there were names such as Juyongguan, Jimenguan and Junduguan. Since then, all generations still call Juyongguankou a lush green cage of flowers and trees among the mountains, just like blue waves and green waves, so it is called "Juyongdiecui" and one of the "Eight Scenes of Yanjing".

Jinshanling

Located in Yinghualougou, Bakes, Luanping County, Rehe, it is named because it was built on the big and small Jinshan between Wuling Peak, the first peak of Yanshan Mountain, and Wohuling Mountain in Gubeikou.

These terraces have different forms, such as square, flat and round piers, awnings, vaults, corners and octagons on the roof, observation platforms with few holes, and rare warehouse buildings along the Great Wall.

Huangyaguan

The Great Wall was built in 556 A.D. in the mountains 3 kilometers north of Jixian County. When Qi Jiguang, a famous Ming Dynasty soldier, was the general commander of Jizhen Town, it was redesigned and overhauled with bricks. The characteristics of this section of the Great Wall building are that the abutment wall has bricks and stones, the enemy building is square and round, and the masonry bricks are hollow and solid. The fortress of Guancheng and the Shuiguan of Enemy Taiwan have everything, connecting the mountains and crossing the river, and the layout is ingenious, which combines great risks and wonders.

Shanhaiguan

is located in the northeast of Qinhuangdao, Hebei province, which is the only pass for traffic between North China and Northeast China in China. In 1381 (the 14th year of Ming Hongwu), General Xu Da built the Great Wall here, and built Guancheng to defend it. Guancheng is named after the Yanshan Mountains, which are surrounded by mountains and peaks, and the Bohai Bay, which is choppy in the south.

It was built in 1372 (the fifth year of Hongwu in the Ming Dynasty), but as early as the Han and Sui Dynasties, piers and abutments had been built. Because of the dangerous terrain and magnificent buildings, it has been called the "Xiongguan in the world" since ancient times, which is the first pass to guard the Hexi Corridor and the only place where the ancient Silk Road must pass.

The phrase "Guilin's landscape is the best in the world" is almost universally known in China. Almost everyone who has been to Guilin thinks that this sentence is not exaggerated. After visiting Guilin, former US President Nixon said, "I have traveled to more than 1 famous cities in more than 8 countries, none of which is as beautiful as Guilin, and none of which is as beautiful as Yangshuo." Guilin is located on both sides of Lijiang River in eastern Guangxi. As early as the Northern and Southern Dynasties, there appeared words praising Guilin's landscape. In the Tang Dynasty, there were many poems praising Guilin. It can be seen that Guilin was a tourist attraction more than 1 years ago. The beauty of Guilin's landscape lies in mountains, caves and water, which is called "Guilin's three wonders".

Forest peaks rise from the ground, standing tall and in various forms. There is an elephant trunk mountain near the Lijiang River. The whole mountain is like an elephant standing by the Lijiang River, stretching its nose and drinking water. There is a unique peak in the center of the city. In the middle of the flat land, one peak protrudes and has a magnificent momentum. Although it is only 6 meters high, it is steep. The lonely peak is like a tower, which looks very beautiful from a distance. When you come to it, you will feel that it is very majestic, so it is also known as the "Southern Sky Column". At the western foot of the mountain, there is a rocky road winding up the mountain, with a grade of ***36. Looking from the top of the mountain, you can see all the scenery. Some people say that if this unique peak is placed in other cities, it will become a great scenic spot, but in Guilin, because there are too many strange peaks, it will not look so eye-catching. In the north of the urban area, Diecai Mountain, which stands by the Lijiang River, is a scenic spot in the city. The main peak, Mingyue Peak, is 223 meters above sea level. Although it is not high, it is quite steep in Guilin. A big pavilion was built on its peak, named "Nayun Pavilion". Here, you can enjoy the Lijiang River that floats around the mountains. Diecai Mountain got its name because this rock is layered, like brocade piled up. There are lush trees on the mountain, and under the shade of green trees, there are buildings such as stacked color pavilions, stacked color doors, Yangzhitang, Yingfeng Building and Wangjiang Pavilion. The strange and beautiful mountains in Guilin include Fubo Mountain, Crescent Mountain, Nanxi Mountain, Hidden Mountain and Xishan Mountain. Guilin's strange caves are the same as its special-shaped mountains. In Guilin, there are countless caves, large and small. Almost every mountain has caves, and the two most famous ones are called Qixingyan and reed flute cave.

However, the most exciting program to visit Guilin is the Lijiang River. Because this clear water, which quietly flows from the edge of Guilin City, passes through the steep mountains, and people are sitting on a slow-moving boat, and the scenery on both sides of the strait is displayed like pictures. Only in the process of swimming the Lijiang River can we enjoy the strange and beautiful mountains in Guilin and truly appreciate the beauty of Guilin's landscape. Generally, you can swim the Lijiang River from Guilin to Yangshuo by yacht, with a water distance of 83 kilometers. Soon after the ship sailed, it crossed the Elephant Trunk Mountain and saw it in the morning, which made the image more beautiful. Far through the mountain, the caves that penetrate the north and south of the mountain are like a bright moon hanging high in the sky. During the 83-kilometer-long tour, in addition to mountains and rivers, fields and farmers appeared from time to time on both sides of the strait. At this time, clusters of bamboos dotted with them were very charming. The Mamo Cliff Stone Carvings in Guilin are very famous, and there are more than 2, stone carvings that have survived to this day. The Longyin Rock and Longyin Cave are the places where the stone carvings are most concentrated. Longyinyan has long been a famous forest of steles in Guihai.
