Changsha

Changsha is the capital of Hunan, China. Located in the lower reaches of the Xiang River in northeastern Hunan, it is the 15th most populous city in China with a population of 10,513,100, the third-most populous city in Central China, and the most livable city in China.

The city forms a part of the Greater Changsha Metropolitan Region along with Zhuzhou and Xiangtan, also known as the Changzhutan City Cluster. Greater Changsha was named one of the 13 emerging mega-cities in China in 2012 by the Economist Intelligence Unit. It is also a National Comprehensive Transportation Hub, and one of the first National Famous Historical and Cultural Cities in China. Changshanese, a kind of Xiang Chinese, is spoken in the downtown area, while Ningxiangnese and Liuyangnese are also spoken in the counties and cities under its jurisdiction. As of the 2020 Chinese census, the prefecture-level city of Changsha had a population of 10,047,914 inhabitants.

Changsha has a history of more than 2,400 years of urban construction, and the name "Changsha" first appeared in the Yi Zhou Shu written in the pre-Qin era. In the Qin dynasty, the Changsha Commandery was set up, and in the Western Han dynasty, the Changsha Kingdom was established. The Tongguan Kiln in Changsha during the Tang dynasty produced the world's earliest underglaze porcelain, which was exported to Western Asia, Africa and Europe. In the period of the Five Dynasties, Changsha was the capital of Southern Chu. In the Northern Song dynasty, the Yuelu Academy (later Hunan University) was one of the four major private academies over the last 1000 years. In the late Qing dynasty, Changsha was one of the four major trade cities for rice and tea in China. In 1904, it was opened to foreign trade, and gradually became a revolutionary city. In Changsha, Tan Sitong established the School of Current Affairs, Huang Xing founded the China Arise Society with the slogan "Expel the Tatar barbarians and revive Zhonghua" (驱除鞑虏，复兴中华), and Mao Zedong also carried out his early political movements here. During the Republican Era, Changsha became one of the major home fronts in the Second Sino-Japanese War, but the subsequent Wenxi Fire in 1938 and the three Battles of Changsha from 1939 to 1942 (1939, 1941 and 1941–42) hit Changsha's economy and urban construction hard.

Changsha is now one of the core cities in the Yangtze River Economic Belt and the Belt and Road Initiative, a Beta- (global second-tier) city by the GaWC, a new Chinese first-tier city and also a pioneering area for China-Africa economic and trade cooperation. Known as the "Construction machinery capital of the world", Changsha has an industrial chain with construction machinery and new materials as the main industries, complemented by automobiles, electronic information, household appliances, and biomedicine. Since the 1990s, Changsha has begun to accelerate economic development, and then achieved the highest growth rate among China's major cities during the 2000s. The Xiangjiang New Area, the first state-level new area in Central China, was established in 2015. As of 2023, more than 180 Global 500 companies have established branches in Changsha. The city has the 21st largest number of skyscrapers in the world. The Human Development Index of Changsha reached 0.817 (very high) in 2016, which is roughly comparable to a moderately developed country.

As of 2023, Changsha hosted 59 institutions of higher education, ranking 8th nationwide among all cities in China. The city houses four Double First-Class Universities of Hunan, National Defense Technology, Central South, and Hunan Normal. It is a major center of research and innovation in the Asia-Pacific with a high level of scientific research outputs, ranking 23rd globally in 2024. Changsha is the birthplace of super hybrid rice, the Tianhe-1 supercomputer, China's first laser 3D printer, and China's first domestic medium-low speed maglev line. Changsha has been named the first "UNESCO City of Media Arts" in China. The city is home to the Hunan Broadcasting System (HBS), the most influential provincial TV station in China.

Chángshā is the pinyin romanization of the Mandarin pronunciation of the Chinese name written 長沙 in traditional characters or 长沙 in simplified ones. The name—meaning "long sandy place"—is attested as early as the 11th century BC, when a vassal lord of the area sent King Cheng of Zhou a gift described as a "Changsha softshell turtle" (长沙鳖; 長沙鼈; Chángshā biē). Its precise origin is unknown but it originally referred to the region around the city rather than the settlement itself. In the 2nd century AD, the historian Ying Shao wrote that the Qin use of the name Changsha for the area was a continuance of its old name.

The Chu settlement in the Changsha area was known as Qingyang. Under the Han, the principality of Changsha called its capital Linxiang ("[Place] Overlooking the Xiang River"). During the Tang and Southern Chu, it was known as Tanzhou from its role overseeing their Tan Prefecture.

Development started around 3000 BC when Changsha developed with the proliferation of Longshan culture, although there is no firm evidence of such a link. Evidence exists that people lived and thrived in the area during the Bronze Age. Numerous examples of pottery and other objects have been discovered.
