Tehran vs Zhuhai

Informations

Tehran (; Persian: تهران‎ Ťehrân [tehˈɾɒːn] (listen)) is the capital of Iran and Tehran Province. With a population of around 8.7 million in the city and 15 million in the larger metropolitan area of Greater Tehran, Tehran is the most populous city in Iran and Western Asia, and has the second-largest metropolitan area in the Middle East (after Cairo). It is ranked 24th in the world by the population of its metropolitan area.In the Classical era, part of the territory of present-day Tehran was occupied by Rhages, a prominent Median city. It was subject to destruction through the medieval Arab, Turkic, and Mongol invasions. Its modern-day inheritor remains as an urban area absorbed into the metropolitan area of Greater Tehran. Tehran was first chosen as the capital of Iran by Agha Mohammad Khan of the Qajar dynasty in 1786, in order to remain within close reach of Iran's territories in the Caucasus, before being separated from Iran as a result of the Russo-Iranian Wars, and to avoid the vying factions of the previously ruling Iranian dynasties. The capital has been moved several times throughout history, and Tehran is the 32nd national capital of Persia. Large-scale demolition and rebuilding began in the 1920s, and Tehran has been a destination for mass migrations from all over Iran since the 20th century.Tehran is home to many historical collections, including the royal complexes of Golestan, Sa'dabad, and Niavaran, where the two last dynasties of the former Imperial State of Iran were seated.

Tehran's most famous landmarks include the Azadi Tower, a memorial built under the reign of Mohammad Reza Shah of the Pahlavi dynasty in 1971 to mark the 2,500th year of the foundation of the Imperial State of Iran, and the Milad Tower, the world's sixth-tallest self-supporting tower which was completed in 2007. The Tabiat Bridge, a newly built landmark, was completed in 2014.The majority of the population of Tehran are Persian-speaking people, and roughly 99% of the population understand and speak Persian, but there are large populations of other ethno-linguistic groups who live in Tehran and speak Persian as a second language.Tehran has an international airport (Imam Khomeini Airport), a domestic airport (Mehrabad Airport), a central railway station, the rapid transit system of Tehran Metro, a bus rapid transit system, trolleybuses, and a large network of highways. There have been plans to relocate Iran's capital from Tehran to another area, due mainly to air pollution and the city's exposure to earthquakes. To date, no definitive plans have been approved. A 2016 survey of 230 cities by consultant Mercer ranked Tehran 203rd for quality of life. According to the Global Destinations Cities Index in 2016, Tehran is among the top ten fastest growing destinations.October 6 is marked as Tehran Day based on a 2016 decision by members of the City Council, celebrating the day when the city was officially chosen as the capital of Iran by the Qajar dynasty back in 1907.

Zhuhai (, Chinese: 珠海; pinyin: Zhūhǎi; Yale: Jyūhói) is a prefecture-level city located on the west bank of Pearl River estuary on the central coast of southern Guangdong province, People's Republic of China, on the southeastern edge of Pearl River Delta. Its name literally means "pearl sea", which originates from the city's location at the mouth of the Pearl River meeting the South China Sea. Zhuhai borders Jiangmen to the west, Zhongshan to the north and Macau to the southeast, and shares maritime boundaries with Shenzhen and Hong Kong to the northeast across the estuary. Zhuhai was one of the original four Special Economic Zones established in 1980, as well as one of China's premier tourist destinations, being called the Chinese Riviera.

While the city is located in the traditionally Cantonese-speaking region of Guangdong, a significant portion of the population is now made up of Mandarin-speaking economic migrants originally from inland provinces. The core of Zhuhai, in the northeastern portion of the administrative division, is part of the Guangdong-Hong Kong-Macau Greater Bay Area, the biggest built-up area in the world with more than 44,478,513 inhabitants at the 2010 census, encompassing Shenzhen, Dongguan, Foshan, Zhongshan, Macau, Hong Kong, the main part of Guangzhou, and small parts of Jiangmen and Huizhou cities. According to a report released in 2014 by the Chinese Academy of Social Sciences, Zhuhai is the most livable city in China.
