4K Beijing Walking on the wall of Yuan Dynasty - China

Yuan Dadu, referred to as Dadu, was the capital of the Yuan Dynasty. It was planned and constructed by Liu Bingzhong, a scientist in the Yuan Dynasty. It was the Yuan Dynasty from Kublai Khan to the fourth year of Yuan Dynasty (1267) to Emperor Yuanshun to the 28th year of Zhengzheng (1368). Jingshi. Its city site is located in the urban area of ​​present-day Beijing, from the Tucheng ruins of Yuanda Capital in the north, Chang'an Avenue in the south and the Second Ring Road in the east and west. The layout of the streets of Yuanta Metropolis established the basic pattern of Beijing today. The city defense system of the Yuan Dynasty includes city walls, gates, and moats. The city wall is built of rammed earth, with a circumference of 60 miles and 240 steps (28.6 kilometers), a height of about 10 to 12 meters, a base width of 20 to 24 meters, and a top width of 10 to 15 meters. The old method of the Song Dynasty was used to build the city, that is, Yongding wood was first installed in the wall, and then horizontal wood was added, and then soil was rammed. Since most of the summer is rainy, the earthen city walls are easily washed and soaked by rain, leading to collapse. Therefore, at the beginning of the construction of the city, it was proposed to cover it with masonry, but it was abandoned due to insufficient financial resources. The Hou Yuan Ting specially deployed the army to harvest reeds and weave reed mats. Every summer, the reed mats were used to cover the walls of the city wall, which was called "Reed City", which was commonly known as the "City of Reeds". However, during Yuan Wenzong, the world was in turmoil, fearing that the people of the uprising would set fire to the reed mats, so the "Reed City" was terminated and replaced with temporary enlistment for repairs whenever the walls collapsed. The direction of the city wall of Yuanda Metropolis is taken in a straight line, 7400 meters from east to west, and 6650 meters long from north to south.
