There are Old Town of Lijiang in Yunnan, Pingyao in Shanxi, Shexian in Anhui and Langzhong in Sichuan. Langzhong Ancient City is located in the north of Sichuan Basin and the middle reaches of Jialing River. The terrain here is dangerous and it has been a military center since ancient times. Compared with other ancient cities, Langzhong is famous for its peculiar geomantic omen. Looking down on Langzhong from the plane, Langzhong City is a beautiful Tai Chi map, which makes Langzhong known as "the first geomantic ancient city in China".

Today, Xiao Zhang won't tell you where Langzhong's "ancient style" is reflected. Today, I will tell you how the reputation of Langzhong Fengshui City came from. Langzhong Ancient City is the best preserved ideal city in ancient China, especially in the Tang Dynasty, which was built according to the theory of astronomical geomantic omen. Geomantic omen theory is a traditional theory about the composition of living environment in ancient China, including the site selection, planning and design of cities and other buildings. It is people-centered, and heaven and earth blend together, thus achieving "the unity of heaven and man". Langzhong Ancient City is a typical example of China's ancient city construction based on "harmony between man and nature". The location and layout of Langzhong ancient city conform to China's traditional geomantic theory, which is the perfect combination of the images of "dragon, sand, water and cave" in China's traditional geomantic omen. The so-called dragon refers to Long Mai, that is, the mountain, where the ancient city of Langzhong is connected with Long Mai. "Sand" refers to the surrounding mountainous terrain. The ancient city of Langzhong takes Panlong Mountain in the north as the town mountain, Jinping Mountain in the south as the case mountain, Jiner Mountain as the Chaoshan Mountain, and the undulating mountains around it are sand mountains. "Water" is a river, and Jialing River is surrounded by the city on three sides, forming a trend of mountains and waters around Jincheng. "Cave dwelling", that is, the base site and buildings, is better to sit facing south. The ruins and buildings of Langzhong ancient city face south. The construction of the ancient city adopts the way of multiple aggregation, which conforms to the traditional geomantic theory and pays attention to the spatial structure of aggregation. Its water and mountains are natural, which constitutes the image pattern of ancient geomantic omen "Xuanwu hangs its head, Suzaku dances, Qinglong winds and white tigers tame" and the structural pattern of landscape cities, which makes it form an ink painting of "holding battlements on three sides and locking smoke clouds on all sides". Du Fu praised that "it is heartbreaking to win things in Langzhong, and the south of Langzhong is sparsely populated", which made Langzhong have the reputation of "Fairyland in Yuen Long" and "Treasure Land of Geomantic omen". From the Western Han Dynasty to the Tang Dynasty, Langzhong has been the main research place of ancient Chinese astronomical geomantic omen, which gave birth to the great astronomer Luoxiahong. Langzhong City is full of gas fields, just like the ancestor of mankind descending from the sky, half lying at the foot of Panlong Mountain, in a symmetrical and orderly mountain shape. In Jinping Mountain, it was the sleeves of ancestors that surrounded his arms and made him bend his knees. Please look at the mountain ahead. It is called Jinping, the first mountain in Jialing. Some people say that standing in the Eight Immortals Cave in Jinping overlooking the ancient city of Langzhong, you can best see the wonderful geomantic omen of the ancient city and the superb ideas of the predecessors to build the city. Du Fu once wrote a poem praising Jin Ping, "I don't know when I come back". Friends, will we feel the same when we stand on it?
