Xi'an, formerly known as Haojing, Chang'an, Jingzhao, Xijing, and Yongzhou, is the capital city of Shaanxi Province, People's Republic of China. It is located in the central part of China, in the south-central part of Shaanxi Province and in the middle of the Weihe Plain. It is a megacity, a national central city, and the core city of the Guanzhong urban agglomeration. Xi'an is a sub-provincial city and the political, economic, cultural, transportation, medical, and educational center of Shaanxi Province and even the northwest region[4][5][6][7]. The total permanent population is 12.9959 million. The Municipal People's Government is located in Weiyang Square, Fengcheng 8th Road, Weiyang District.
Xi'an is a famous cultural and tourist city in China and even in the world. It has a very profound historical and cultural heritage and is well-known at home and abroad. It is the first city in Chinese history to be called Jing. It has a history of more than 3,100 years of city construction[8][9] and more than 1,070 years of capital history. In history, many prosperous dynasties, including Zhou, Qin, Western Han, Sui, and Tang, had their capitals here [10], which made Xi'an witness the peak period of openness, extroversion, martial spirit, and prosperity in Chinese history, and left a huge amount of relics. Xi'an currently has two of the six world cultural heritage sites and is also the starting point of the Silk Road [Note 1]. The main urban area of Xi'an still retains the complete Ming Dynasty city walls and gates, moats and bridges, corner towers, urn cities, arrow towers and other facilities. In and around the city, there are a large number of ancient cultural relics such as the Mausoleum of Qin Shihuang, the Han Yang Mausoleum, the ruins of the Han Chang'an City, and the ruins of the Tang Daming Palace, which are of extremely high archaeological research value.
In terms of geography and transportation, Xi'an is located in the middle of the Weihe Plain in Guanzhong. The Weihe River, the largest tributary of the Yellow River, flows from the north of the city from southwest to northeast. There are also rivers such as the Chanhe River, the Bahe River, and the Jinghe River in the north and west. It is known as "Eight Rivers Surrounding Chang'an", all of which are ecological protection areas. It is adjacent to the northern slope of the Qinling Mountains in the south and is also close to the intersection of the climates of northern and southern China. Due to its geographical location in the center of the country, Xi'an is a gateway city and an important transportation hub for the Yangtze River Delta, the Pearl River Delta, and the Beijing-Tianjin-Hebei region to the northwest and southwest. It is also a must-go place for the northwest region to go to the eastern and southern regions of the country. Xi'an Railway Station is located on the Longhai Railway and is a hub station with huge transportation volume. Xi'an currently has the 4F-level Xi'an Xianyang International Airport and domestic high-speed rail transportation hubs such as Xi'an North Station. In terms of urban transportation, Xi'an currently has 11 operating subway lines with a total mileage of 403 kilometers. It also operates the Xihu Line of the urban rail and the tram Gaoxin Yunba.
Xi'an is one of China's national central cities, an important city in the Silk Road Economic Belt, the New Eurasian Continental Bridge and the Yellow River Basin, and the economic, technological, educational, energy, financial, cultural and commercial center of the Guanzhong Urban Agglomeration. Its Yanliang District is an important aviation industry base in China. In 2009, the State Council approved the "Development Plan for the Guanzhong-Tianshui Economic Zone", proposing to build Xi'an into an important national science and technology research and development center, a regional trade, logistics, exhibition center, a regional financial center, a world-class tourist destination, and an important national high-tech industry and advanced manufacturing base, and strive to build Xi'an into an international metropolis. In 2013, the State Council approved the establishment of Xixian New Area, becoming China's seventh national new area. Most of the areas under the jurisdiction of the China (Shaanxi) Pilot Free Trade Zone established in 2017 are located in Xi'an. In February 2018, the National Development and Reform Commission and the Ministry of Housing and Urban-Rural Development issued the "Development Plan for the Guanzhong Plain Urban Agglomeration" to support Xi'an in building a national central city, an international comprehensive transportation hub, and an international metropolis with historical and cultural characteristics.
In terms of administrative divisions, it currently has jurisdiction over 11 districts and 2 counties and fully administers Xixian New Area, with a total area of about 10,700 square kilometers (including Xixian New Area), and several officially designated economic management zones such as the High-tech Zone, Qujiang New Area, and Economic Development Zone. The Xi'an Municipal Party Committee, Municipal Government and other party and government agencies are located in the administrative center of Weiyang District.
