# Xi'an

Xi'an is the capital of the Chinese province of Shaanxi. A sub-provincial city on the Guanzhong plain, the city is the third-most populous city in Western China after Chongqing and Chengdu, as well as the most populous city in Northwestern China. Its total population was 12.95 million as of the 2020 census, including an urban population of 9.28 million.
Known as Chang'an throughout much of its history, Xi'an is one of China's Four Great Ancient Capitals, having held the position under several of the most important dynasties in Chinese history, including the Western Zhou, Qin, Western Han, Sui, Northern Zhou and Tang. Xi'an is now the second-most popular tourist destination in China. The city was one of the terminal points on the Silk Road during the ancient and medieval eras, as well as the home of the 3rd-century BC Terracotta Army commissioned by Emperor Qin Shi Huang—both of which are listed as World Heritage Sites by UNESCO.
Since the 1980s, as part of the economic growth of inland China especially for the central and northwest regions, Xi'an has matured into a cultural, industrial, political and educational, and research and development hub. Xi'an currently holds sub-provincial status, administering 11 districts and 2 counties. In 2020, Xi'an was ranked as a Beta- (global second tier) city by the Globalization and World Cities Research Network, and, according to the country's own ranking, ranked 17th; it is also one of the world's top 100 financial centers according to the Global Financial Centres Index. Xi'an is ranked by the Nature Index as one of the top 20 cities globally by scientific research output, and is home to multiple prestigious educational institutions, such as Xi'an Jiaotong University, Northwestern Polytechnical University, Xidian University and Northwest University.

## Name

"Xi'an" is the atonal pinyin romanization of its Chinese name 西安, Western Peace. (The apostrophe – known in Chinese as a 隔音符號, géyīn fúhào – should be included to distinguish its pronunciation from the single syllable xian.) The name was adopted in 1369 under the early Ming dynasty. Jesuit missionaries recorded its name as "Si-ngan" or "Si-ngan-fou" from its status as the seat of a prefecture (府, fǔ). This form still appears in the Latin name of the Catholic diocese of Xi'an, archidioecesis Singanensis. The name was later romanized as "Hsi-an" by Wade & Giles and as "Sianfu" or "Sian" by the imperial post office, both of which were common until the promulgation of pinyin.
The area of present-day Xi'an has been the site of several important former Chinese cities. The capital of the Western Zhou were the twin cities of Feng and Hao, known collectively as Fenghao, located on opposite banks of the Feng River at its confluence with the southern bank of the Wei in the western suburbs of present-day Xi'an. The Qin capital Xianyang was erected north of the Wei during the Warring States period and was succeeded by the Western Han capital of Chang'an (長安), meaning "Perpetual Peace", which was located south of the Wei and covered the central area of present-day Xi'an. During the Eastern Han, Chang'an was also known as the "Western Capital" (西京), named for its namesake position relative to the main capital at Luoyang. Under the Sui, its name became Daxing (大興, "Greatly Prosperous") in AD 581. Under the Tang, the name reverted to Chang'an in 618. Under the Mongolian Yuan dynasty (13th & 14th centuries), it held a succession of names: Fengyuan (奉元), Anxi (安西, "Peaceful West") and Jingzhao (京兆). The Ming name "Xi'an" was changed back to Xijing ("Western Capital", as above) between 1930 and 1943.

## History
### Prehistory

The Lantian Man was discovered in 1963 in Lantian County, 50 km (31 mi) southeast of Xi'an, and dates back to at least 500,000 years before the present time. A 6,500-year-old Neolithic village, Banpo, was discovered in 1953 on the eastern outskirts of the city proper, which contains the remains of several well organized Neolithic settlements carbon dated to 5,600–6,700 years ago. The site is now home to the Xi'an Banpo Museum, built in 1957 to preserve the archaeological collection.

### Ancient era

Xi'an became a cultural and political center of China in the 11th century BC with the founding of the Zhou dynasty. The capital of Zhou was established in the twin settlements of Fengjing (灃京) and Haojing (鎬京), together known as Fenghao, located southwest of contemporary Xi'an. The settlement was also known as Zōngzhōu (宗周) to indicate its role as the capital of the vassal states. In 738 BC, King Ping of Zhou moved the capital to Luoyang due to political unrest.

### Imperial era

Following the Warring States period, China was unified under the Qin dynasty (221–206 BC) for the first time, with the capital located at Xianyang, just northwest of modern Xi'an. The first emperor of China, Qin Shi Huang ordered the construction of the Terracotta Army and his mausoleum just to the east of Xi'an almost immediately after his ascension to the throne.
In 202 BC, the founding emperor Liu Bang of the Han dynasty established his capital in Chang'an County; his first palace, Changle Palace (長樂宮, "Perpetual Happiness") was built across the river from the ruin of the Qin capital. This is traditionally regarded as the founding date of Chang'an. Two years later, Liu Bang built Weiyang Palace (未央宮, "Never Ending Palace") north of modern Xi'an. Weiyang Palace was the largest palace ever built on Earth, covering 4.8 square kilometers (1,200 acres), which is 6.7 times the size of the current Forbidden City and 11 times the size of the Vatican City. The original Xi'an city wall was started in 194 BC and took 4 years to finish. Upon completion, the wall measured 25.7 km (15.97 mi) in length and 12 to 16 m (39.37–52.49 ft) in thickness at the base, enclosing an area of 36 km$^2$ (13.90 sq mi). In the year 190, amidst uprisings and rebellions just prior to the Three Kingdoms period, Dong Zhuo, a powerful warlord from nearby Xiliang, moved the court from Luoyang to Chang'an in a bid to avoid a coalition of other powerful warlords against him.
In 582, shortly after the Sui dynasty was founded, the emperor of Sui ordered a new capital to be built southeast of the Han capital, called Daxing (大興, "Great prosperity"). It consisted of three sections: the Imperial City, the palace section, and the civilian section, with a total area of 84 km$^2$ (32 sq mi) within the city walls. At the time, it was the largest city in the world. The city was renamed Chang'an by the Tang dynasty. In the mid-7th century, after returning from his pilgrimage to India, the Buddhist monk Xuanzang established a translation school for Sanskrit scriptures.
Construction of the Giant Wild Goose Pagoda began in 652. This pagoda was 64 m (209.97 ft) in height, and was built to store the translations of Buddhist sutras obtained from India by Xuanzang. In 707, construction of the Small Wild Goose Pagoda began. This pagoda measured 45 m (147.64 ft) tall at the time of completion, and was built to store the translations of Buddhist sutras by Yijing. The massive 1556 Shaanxi earthquake eventually damaged the tower and reduced its height to 43.4 m (142.39 ft).
The Nestorian Stele is a Tang Chinese stele erected in 781 that documents 150 years of early Christianity in China. It is a 279 cm tall limestone block with text in both Chinese and Syriac describing the existence of Christian communities in several cities in northern China. It reveals that the initial Nestorian Christian church had met recognition by the Tang Emperor Taizong, due to efforts of the Christian missionary Alopen in 635.
Chang'an was devastated at the end of the Tang dynasty in 904. Residents were forced to move to the new capital city in Luoyang, and a small area in the city continued to be occupied thereafter.
In the era of the Song dynasty, Xi'an was an important cultural center of scholarship and innovation on matters such as science, as well as historiography, religion, and philosophy in China. The Northern Song era saw its people, political culture, and strategic location be directly utilized by the Song dynasty proper and its continued relevance to Muslim travelers into China and Chinese Muslim residents.
During the Ming dynasty, a new wall was constructed in 1370 which remains intact to this day. The wall measures 11.9 km (7.4 mi) in circumference, 12 m (39.37 ft) in height, and 15 to 18 m (49.21–59.06 ft) in thickness at the base; a moat was also built outside the walls. The new wall and moat would protect a much smaller city of 12 km$^2$ (4.6 sq mi).

### Modern era

The Qing dynasty established a walled off Manchu banner quarter in northeast Xi'an, on the site of the former palace of the Ming Prince of Qin. A Han banner quarter was established in the southeast of the city.
Manchu bannermen from the Xi'an banner garrison were praised for maintaining Manchu culture by Kangxi in 1703. Xi'an garrison Manchus were said to retain Manchu culture far better than all other Manchus at martial skills in the provincial garrisons and they were able to draw their bows properly and perform cavalry archery, unlike Beijing Manchus. The Qianlong emperor received a memorial staying Xi'an Manchu bannermen still had martial skills, although not up to those, in the past in a 1737 memorial from Cimbu. By the 1780s, the military skills of Xi'an Manchu bannermen dropped enormously, and they had been regarded as the most militarily skilled provincial Manchu banner garrison. Manchu women from the Xi'an garrison often left the walled Manchu garrison and went to hot springs outside the city, and gained bad reputations for their sexual lives. A Manchu from Beijing, Sumurji, was shocked and disgusted by this after being appointed Lieutenant general of the Manchu garrison of Xi'an and informed the Yongzheng emperor what they were doing. Han civilians and Manchu bannermen in Xi'an had bad relations, with the bannermen trying to steal at the markets. Manchu Lieutenant general Cimbru reported this to Yongzheng emperor in 1729, after he was assigned there. Governor Yue Rui of Shandong was then ordered by the Yongzheng to report any bannerman misbehaving and warned him not to cover it up in 1730, after Manchu bannermen were put in a quarter in Qingzhou. Manchu bannermen from the garrisons in Xi'an and Jingzhou fought in Xinjiang in the 1770s and Manchus from Xi'an garrison fought in other campaigns against the Dzungars and Uyghurs throughout the 1690s and 18th century. In the 1720s Jingzhou, Hangzhou, and Nanjing Manchu banner garrisons fought in Tibet.
For the over 200 years they lived next to each other, Han civilians and Manchu bannermen of both genders in Xi'an did not intermarry with each other at all. The Qing dynasty altered its law on intermarriage between Han civilians and Manchu bannermen several times in the dynasty. At the beginning of the Qing dynasty, the Qing allowed Han civilians to marry Manchu women. Then the Qing banned civilians from marrying women from the Eight banners later. In 1865, the Qing allowed Han civilian men to marry Manchu bannerwomen in all garrisons, except the capital garrison of Beijing. There was no formal law on marriage between people in the different banners, like the Manchu and Han banners, but it was informally regulated by social status and custom. In northeastern China, such as Heilongjiang and Liaoning, it was more common for Manchu women to marry Han men, since they were not subjected to the same laws and institutional oversight as Manchus and Han in Beijing and elsewhere.
In October 1911, during the Xinhai revolution, revolutionaries stormed the Manchu fort in Xi'an. Most of the city's 20,000 Manchus were killed. Hui (Muslims; then referred to as "Mohammedans") were divided in its support for the revolution. Those of Shaanxi supported the revolutionaries, while those of Gansu supported the Qing. The Hui of Xi'an (Shaanxi province) joined the Han Chinese revolutionaries in slaughtering the Manchus. Some wealthy Manchus survived by being ransomed. Wealthy Han Chinese enslaved Manchu girls and poor Han Chinese troops seized young Manchu women as wives. Hui Muslims also seized young pretty Manchu girls and raised them as Muslims.
A British missionary who witnessed the massacre commented that "Old and young, men and women, children alike, were all butchered... Houses were plundered and then burnt; those who would fain have laid hidden till the storm was past, were forced to come out into the open. The revolutionaries, protected by a parapet of the wall, poured a heavy, unceasing, relentless fire into the doomed Tartar (Manchu) city, those who tried to escape thence into the Chinese city were cut down as they emerged from the gates."
In 1936, the Xi'an (then "Sian") Incident took place in the city during the Chinese Civil War. The incident helped to bring the Kuomintang (KMT) and Chinese Communist Party to form the Second United Front in order to concentrate on fighting against the Imperial Japanese Army in the Second Sino-Japanese War.
On March 11, 1938, an aerial battle broke out for the first time over Xi'an as Imperial Japanese Army Air Force aircraft attacked the city, and was engaged by Chinese Air Force I-15 fighter planes, led by Lt. Cen Zeliu of the 5th Pursuit Group, 17th Squadron. While repeatedly attacked by air, Shaanxi was heavily fortified by units of the Eighth Route Army; Xi'an was never taken by the Japanese forces.
On May 20, 1949, the Communist-controlled People's Liberation Army captured the city of Xi'an from the Kuomintang force.
During the Mao era, Xi'an was further developed as part of the Third Front Construction.$^{:186}$
Xi'an made headlines for being one of the many cities where the 2012 China anti-Japanese demonstrations occurred.
In 2022, Xi'an witnessed the largest COVID-19 community outbreak since the initial months of the pandemic hit China. From December 23, 2021, the city was put into strict lockdown after local authorities reported more than 250 cases, traced to the Delta variant by authorities. This led to stressed healthcare and delayed or insufficient food deliveries to some part of the city. Restrictions of Xi'an were lifted on January 24.

## Geography

Xi'an lies on the Guanzhong Plain in the south-central part of Shaanxi province, on a flood plain created by the eight surrounding rivers and streams.
The city borders the northern foot of the Qin Mountains (Qinling) to the south, and the banks of the Wei River to the north. Hua Shan, one of the five sacred Taoist mountains, is located 100 km (62 mi) away to the east of the city. Not far to the north is the Loess Plateau.
At the beginning of Han dynasty, the Chief of Staff Zhang Liang advised the emperor Liu Bang to choose Guanzhong as the capital of the Han dynasty: "Guanzhong Plain is located behind Mount Xiao and Hangu Pass, and connects Long (Gansu) and Shu (Sichuan). The area can be called an irony castle spreads for thousands of miles, and is rich in harvest like the nation of heaven." (关中左崤函，右陇蜀，沃野千里，此所谓金城千里，天府之国也) Since then, Guanzhong is also known as the 'Nation of the Heaven'.

## Climate

Xi'an has a temperate climate that is influenced by the East Asian monsoon, classified under the Köppen climate classification as a borderline humid subtropical and humid continental climate (Cwa/Dwa). The Wei River valley is characterized by hot, humid summers, cold, dry winters, and dry springs and autumns. Most of the annual precipitation is delivered from July to late October. Snow occasionally falls in winter but rarely settles for long. Dust storms often occur during March and April as the city rapidly warms up. Summer months also experience frequent but short thunderstorms. The monthly 24-hour average temperature ranges from around the freezing mark in January to 27.0 °C (80.6 °F) in July, with an annual mean of 14.08 °C (57.3 °F). Extremes since 1951 have ranged from −20.6 °C (−5 °F) on January 11, 1955, to 41.8 °C (107 °F) on June 21, 1998. A highest record of 42.9 °C (109 °F) was registered in another station on June 17, 2006. An unofficial record low of −25.0 °C (−13 °F) was also recorded in January 1930, but at another weather station in the northern suburbs of the city.

### National Time Service Center

The Shaanxi Astronomical Observatory was established in 1966. In 1975, according to the Geodetic Origin Report of the People's Republic of China, 'in order to avoid bias in the mensuration as much as possible, the Geodetic Origin would be in central mainland China.' Lintong (临潼), a town near Xi'an was chosen. Since 1986, Chinese Standard Time (CST) was set from NTSC. The National Time Service Center (NTSC), the Chinese Academy of Sciences is an institute which is mainly engaged in the service and research on time and frequency. NTSC takes charge of generating and maintaining the national standard time scale, disseminating the time and frequency signals. The autonomous standard time scales of universal time and atomic time and the dissemination techniques with LF radio and HF radio were established successively during the 1970s and 1980s, which meet all the requirements for different applications on the whole, such as the scientific researches, national economy, etc.

## Demographics

As of 2010 Xi'an has a population of 5.4 million. Compared to the census data from 2007, the population has increased by 1.4 million persons. The population is 51.66 percent male and 48.34 percent female. Among its districts, Yanta has the largest population, with around 1.08 million inhabitants.
The Xi'an metropolitan area was estimated by the OECD (Organisation for Economic Co-operation and Development) to have, as of 2010, a population of 12.9 million, of which 5,740,000 is urban.

## Transportation

Xi'an has many areas that are easily accessible on foot. In many commercial, residential, educational zones in the city, especially in the shopping and entertainment districts around the Bell Tower, underpasses and overpasses have been built for the safety and convenience of pedestrians.
A bicycle sharing network started operating in Xi'an from the year 2013 and today has 52,000 bikes, used by over 200,000 people per day. Taxi services are numerous, but many citizens of Xi'an still commute to work using the city's 270 official municipal bus routes serviced by a fleet of over 7,800 buses, with an average system-wide ridership of over 4 million people per day. The bus network is complemented by a rapidly expanding subway system that carries over 1.5 million commuters per day. There are more than 2 million registered automobiles in Xi'an; the growing number of personal automobiles also means traffic jams are a common urban issue.

### Metro

Line 2, running through the city from north (North Railway Station) to south (Weiqu Nan), was the first line opened to the public on September 16, 2011. Operations began on September 28, 2011.
