What is Los Angeles?

You can look at Jiayuguan's introduction to Los Angeles. Jiayuguan is the starting point of the western end of Wan Li Great Wall in Ming Dynasty, the most spectacular and well-preserved ancient military castle along the Great Wall in Ming Dynasty, and also an important military fortress along the Great Wall in Ming Dynasty and later generations. Known as "great defense at home and abroad" and "the first pass in Hexi". Jiayuguan is located at the junction of China and the West in Hexi Corridor (west of the central part), with a history of 63 1 year. It was built nine years before Shanhaiguan. In the early Ming Dynasty, Song Xianggong and General Sheng Feng were on their way to victory. He chose to build a pass at the west foot of Jiayu Plateau, which is located in the middle of Hexi Corridor, bordering Jiuquan in the east, Yumen in the west, Montenegro in the back and Qilian in the south. Guancheng was founded in the fifth year of Hongwu in the Ming Dynasty (A.D. 1372), lasted for 168, and was completed in A.D. 1540. As the historical material "Qin Bianlue" records: "There was water at the beginning, and then there was closure. With architecture, the Great Wall will be built later, and the Great Wall can be defended later. " Jiayuguan Guancheng has a reasonable layout and excellent architecture. There are three battlements in Guancheng, many lines of defense, one city in the city and one moat outside the city, forming the trend of guarding the city. It consists of: inner city, urn, Luocheng, moat, three-story and three-eaves, high-rise pavilion resting on the top of the mountain, moat, great wall peak platform and so on. The inner city is the main body and center of Guancheng, with a circumference of 640 meters and an area of 25,000 square meters. Outside the inner city and the west gate, there are urn retreats, each with an area of more than 500 square meters. The urn doors all face south, and there is Los Angeles in the west of the urn. The middle of the city wall is closed to the west, and the word "Jiayuguan" is engraved on the lintel. The existing buildings in Guancheng mainly include guerrilla headquarters, Guan Jing, Guandi Temple, stage and Wenchang Pavilion. Jiayuguan Guancheng is surrounded by mountains and waters, guarding the canyon area about15km wide from north to south, and the Qiu Lai Valley in the south of the canyon constitutes a natural barrier for customs clearance. Beacon docks crisscross Jiayuguan, and there are 66 docks in Guancheng, east, west, north, south and northeast. Jiayuguan is a natural terrain with both offensive and defensive capabilities. It forms a strict military defense system with the nearby Great Wall, city platform, moat, beacon tower and other facilities, and is also known as "the first male pass in the world". The stage was built by Bao Shiyi, a guerrilla general in Jiayuguan, in the fifty-seventh year of Qianlong in Qing Dynasty (AD 1792). In the past, it was an entertainment place for officers and men guarding the city, city residents and business travelers. Its modeling is a typical traditional classical stage in China. The wooden screen separates the foreground from the background, and there are eight figures painted in the center of the screen, which is the familiar content of the "Eight Immortals". At the top is the traditional Chinese pattern "Eight Diagrams", which is a comprehensive reflection of China's ancient thoughts, culture and science. On both sides are a group of amorous feelings murals, which are about monks in temples, nuns in nuns and beautiful women raised by nuns. These paintings are very rare on other stages. There are couplets written on both sides of the stage: "The joys and sorrows of the past were exhausted, and fools were loyal to the scene." Couplets highly summarize the historical changes of human affairs and the role of traditional Chinese opera performance places in past dynasties. Wenchang Pavilion Wenchang Pavilion was built in the Ming Dynasty and rebuilt in the second year of Daoguang reign (AD 1822). The pavilion is a two-story building, with two eaves resting on the top of the mountain, single rooms on both sides of the ground floor and 18 red paint columns around it, forming a cloister. Inside is the official hall, three wide and two deep. There are lattice doors and windows on all sides, and more than 80 colorful landscape figure paintings are painted on the upper part. In the Ming and Qing dynasties, this pavilion was a place where literati met and made friends, recited poems and painted pictures, and read books. In the late Qing dynasty, it became the place where civil servants worked. Outside the west gate of "Tianxia Xiongguan" stone tablet 100 meters, there is a "Tianxia Xiongguan" stone tablet printed in Qing Dynasty. In the 14th year of Jiaqing, Qing Dynasty (1809), when Li, the general of Suzhou Town, inspected Jiayuguan defense, he saw that there was Qilian Mountain in the south and Montenegro in the north, and the style was magnificent, so he wrote down the word "the first pass in the world" and took this stone as a monument. Left an eternal memorial for future generations. The word "full moon" is engraved on the west gate of the inner city of the Moon Gate, which means that in order to realize the long-term and stable strategy of governing the country, the Ming Dynasty implemented the "Huairou" policy towards the nomadic people in the frontier (outside the customs) to appease the remote areas. The inner wall of the inner city is 9m high, with overlapping wall1.7m and total height10.7m.. Less than 6 meters with loess rammer, more than 6 meters with adobe masonry. After more than 600 years, although the wall has peeled off, most of it is still intact and firm. According to legend, the loess used to build the city wall was carefully screened and processed. First, put the selected loess on the bluestone board, bake it in the scorching sun, and dry the grass seeds. The "Great Wall Badge" unearthed under the Great Wall in the northern section of Jiayu recorded in detail the division of labor in repairing the Great Wall at that time. The Great Wall badge is now on display in Jiayuguan Great Wall Museum. The badge is made of stone, with the words "I started work" engraved on the front, "Cai Zhimei started work" engraved on the back, and the names of the captains of various engineering teams who built the Great Wall engraved below. After the completion of the construction project, strict acceptance should be carried out: within a certain distance from the wall, shoot the wall with an arrow, if the arrow can not penetrate, it will prove that the wall is solid and qualified; If the arrow shoots into the wall, it proves that the project is unqualified and needs to be reworked and rebuilt. The strict management system of the Great Wall Project ensures the quality of the Great Wall Project. Luocheng and Arrow Tower Luocheng were founded in the eighth year of Hongzhi in Ming Dynasty (1495), and were presided over by Suzhou soldier Li Duan Cheng. "Los Angeles" is the front of the enemy, and the "convex" shaped walls are all made of bricks, which is very strong. There are "arrow towers" at the north and south ends of "Los Angeles", which are facilities for watching the fire in Kansai, Guannan and Guanbei. Both ends are connected with the external wall, and the external wall is connected with the North and South Great Wall of Guancheng. There are turrets and enemy towers at the four corners of the turret inner city, also known as the "garrison building", which looks like a bunker and is the place where soldiers guarding the city are on duty. There are watchtowers on the north and south city walls, where weapons are placed. Looking back from here, the three tall buildings, Guanghua Building, Rouyuan Building and Jiayuguan Building, are on the same central axis. This architectural form of "through-hole doors" and high platforms and pavilions is the continuous development of China's architectural history and forms for thousands of years. Hehe, I hope it will help you. Q: I don't know much. Just introduce it directly.
