A metropolitan area, sometimes referred to as a metro area or commuter belt, is a region consisting of a densely populated urban core and its less-populated surrounding territories, sharing industry and housing. A metro area comprises multiple jurisdictions and municipalities: neighborhoods, boroughs, towns, suburbs, districts and nations like the eurodistricts; as social and political institutions have changed, metropolitan areas have become key economic and political regions. Metropolitan areas include one or more urban areas, as well as satellite cities and intervening rural areas that are socioeconomically tied to the urban core measured by commuting patterns. In the United States, the concept of the metropolitan statistical area has gained prominence. Metropolitan areas may themselves be part of larger megalopolises. For urban centres outside metropolitan areas, that generate a similar attraction at smaller scale for their region, the concept of the regiopolis and regiopolitan area or regio was introduced by German professors in 2006.
In the United States, the term micropolitan statistical area is used. A metropolitan area combines an urban agglomeration with zones not urban in character, but bound to the center by employment or other commerce; these outlying zones are sometimes known as a commuter belt, may extend well beyond the urban zone, to other political entities. For example, New York on Long Island is considered part of the New York metropolitan area. In practice, the parameters of metropolitan areas, in both official and unofficial usage, are not consistent. Sometimes they are little different from an urban area, in other cases they cover broad regions that have little relation to a single urban settlement. Population figures given for one metro area can vary by millions. There has been no significant change in the basic concept of metropolitan areas since its adoption in 1950, although significant changes in geographic distributions have occurred since and more are expected; because of the fluidity of the term "metropolitan statistical area," the term used colloquially is more "metro service area," "metro area," or "MSA" taken to include not only a city, but surrounding suburban and sometimes rural areas, all which it is presumed to influence.
A polycentric metropolitan area contains multiple urban agglomerations not connected by continuous development. In defining a metropolitan area, it is sufficient that a city or cities form a nucleus with which other areas have a high degree of integration. See the many lists of metropolitan areas itemized at § Lists of metropolitan areas; the Australian Bureau of Statistics defines Greater Capital City Statistical Areas as the areas of functional extent of the seven state capitals and the Australian Capital Territory. GCCSAs replaced "Statistical Divisions" used until 2011. In Brazil, metropolitan areas are called "metropolitan regions"; each State defines its own legislation for the creation and organization of a metropolitan region. The creation of a metropolitan region is not intended for any statistical purpose, although the Brazilian Institute of Geography and Statistics uses them in its reports, their main purpose is to allow for a better management of public policies of common interest to all cities involved.
They don't have political, electoral or jurisdictional power whatsoever, so citizens living in a metropolitan region do not elect representatives for them. Statistics Canada defines a census metropolitan area as an area consisting of one or more adjacent municipalities situated around a major urban core. To form a CMA, the metropolitan area must have a population of at least 100,000, at least half within the urban core. To be included in the CMA, adjacent municipalities must have a high degree of integration with the core, as measured by commuter flows derived from census data. In Chinese, there used to be no clear distinction between "megalopolis" and "metropolitan area" until National Development and Reform Commission issued Guidelines on the Cultivation and Development of Modern Metropolitan Areas on Feb 19, 2019, in which a metropolitan area was defined as "an urbanized spatial form in a megalopolis dominated by supercity or megacity, or a large metropolis playing a leading part, within the basic range of 1-hour commute area."
The European Union's statistical agency, has created a concept named Larger Urban Zone. The LUZ represents an attempt at a harmonised definition of the metropolitan area, the goal was to have an area from a significant share of the resident commute into the city, a concept known as the "functional urban region". France's national statistics institute, the INSEE, names an urban core and its surrounding area of commuter influence an aire urbaine; this statistical method applies to agglomerations of all sizes, but the INSEE sometimes uses the term aire métropolitaine to refer to France's largest aires urbaines. In German definition, metropolian areas are eleven most densely populated areas in the Federal Republic of Germany, they comprise the major German cities and their surrounding catchment areas and form the political and cultural centres of the country. For urban centres outside metropolitan areas, that generate a similar attraction at smaller scale for their region, the concept of the Regiopolis and regiopolitan area or regio was introduced by German professors in 2006.
In India, a metropolitan city is defin
Hanyu Pinyin abbreviated to pinyin, is the official romanization system for Standard Chinese in mainland China and to some extent in Taiwan. It is used to teach Standard Mandarin Chinese, written using Chinese characters; the system includes four diacritics denoting tones. Pinyin without tone marks is used to spell Chinese names and words in languages written with the Latin alphabet, in certain computer input methods to enter Chinese characters; the pinyin system was developed in the 1950s by many linguists, including Zhou Youguang, based on earlier forms of romanizations of Chinese. It was published by revised several times; the International Organization for Standardization adopted pinyin as an international standard in 1982, was followed by the United Nations in 1986. The system was adopted as the official standard in Taiwan in 2009, where it is used for international events rather than for educational or computer-input purposes, but "some cities and organizations, notably in the south of Taiwan, did not accept this", so it remains one of several rival romanization systems in use.
The word Hànyǔ means'the spoken language of the Han people', while Pīnyīn means'spelled sounds'. In 1605, the Jesuit missionary Matteo Ricci published Xizi Qiji in Beijing; this was the first book to use the Roman alphabet to write the Chinese language. Twenty years another Jesuit in China, Nicolas Trigault, issued his Xi Ru Ermu Zi at Hangzhou. Neither book had much immediate impact on the way in which Chinese thought about their writing system, the romanizations they described were intended more for Westerners than for the Chinese. One of the earliest Chinese thinkers to relate Western alphabets to Chinese was late Ming to early Qing dynasty scholar-official, Fang Yizhi; the first late Qing reformer to propose that China adopt a system of spelling was Song Shu. A student of the great scholars Yu Yue and Zhang Taiyan, Song had been to Japan and observed the stunning effect of the kana syllabaries and Western learning there; this galvanized him into activity on a number of fronts, one of the most important being reform of the script.
While Song did not himself create a system for spelling Sinitic languages, his discussion proved fertile and led to a proliferation of schemes for phonetic scripts. The Wade–Giles system was produced by Thomas Wade in 1859, further improved by Herbert Giles in the Chinese–English Dictionary of 1892, it was popular and used in English-language publications outside China until 1979. In the early 1930s, Communist Party of China leaders trained in Moscow introduced a phonetic alphabet using Roman letters, developed in the Soviet Oriental Institute of Leningrad and was intended to improve literacy in the Russian Far East; this Sin Wenz or "New Writing" was much more linguistically sophisticated than earlier alphabets, but with the major exception that it did not indicate tones of Chinese. In 1940, several thousand members attended a Border Region Sin Wenz Society convention. Mao Zedong and Zhu De, head of the army, both contributed their calligraphy for the masthead of the Sin Wenz Society's new journal.
Outside the CCP, other prominent supporters included Sun Fo. Over thirty journals soon appeared written in Sin Wenz, plus large numbers of translations, some contemporary Chinese literature, a spectrum of textbooks. In 1940, the movement reached an apex when Mao's Border Region Government declared that the Sin Wenz had the same legal status as traditional characters in government and public documents. Many educators and political leaders looked forward to the day when they would be universally accepted and replace Chinese characters. Opposition arose, because the system was less well adapted to writing regional languages, therefore would require learning Mandarin. Sin Wenz fell into relative disuse during the following years. In 1943, the U. S. military engaged Yale University to develop a romanization of Mandarin Chinese for its pilots flying over China. The resulting system is close to pinyin, but does not use English letters in unfamiliar ways. Medial semivowels are written with y and w, apical vowels with r or z.
Accent marks are used to indicate tone. Pinyin was created by Chinese linguists, including Zhou Youguang, as part of a Chinese government project in the 1950s. Zhou is called "the father of pinyin," Zhou worked as a banker in New York when he decided to return to China to help rebuild the country after the establishment of the People's Republic of China in 1949, he became an economics professor in Shanghai, in 1955, when China's Ministry of Education created a Committee for the Reform of the Chinese Written Language, Premier Zhou Enlai assigned Zhou Youguang the task of developing a new romanization system, despite the fact that he was not a professional linguist. Hanyu Pinyin was based on several existing systems: Gwoyeu Romatzyh of 1928, Latinxua Sin Wenz of 1931, the diacritic markings from zhuyin. "I'm not the father of pinyin," Zhou said years later. It's a lo
China the People's Republic of China, is a country in East Asia and the world's most populous country, with a population of around 1.404 billion. Covering 9,600,000 square kilometers, it is the third- or fourth-largest country by total area. Governed by the Communist Party of China, the state exercises jurisdiction over 22 provinces, five autonomous regions, four direct-controlled municipalities, the special administrative regions of Hong Kong and Macau. China emerged as one of the world's earliest civilizations, in the fertile basin of the Yellow River in the North China Plain. For millennia, China's political system was based on hereditary monarchies, or dynasties, beginning with the semi-legendary Xia dynasty in 21st century BCE. Since China has expanded, re-unified numerous times. In the 3rd century BCE, the Qin established the first Chinese empire; the succeeding Han dynasty, which ruled from 206 BC until 220 AD, saw some of the most advanced technology at that time, including papermaking and the compass, along with agricultural and medical improvements.
The invention of gunpowder and movable type in the Tang dynasty and Northern Song completed the Four Great Inventions. Tang culture spread in Asia, as the new Silk Route brought traders to as far as Mesopotamia and Horn of Africa. Dynastic rule ended in 1912 with the Xinhai Revolution; the Chinese Civil War resulted in a division of territory in 1949, when the Communist Party of China established the People's Republic of China, a unitary one-party sovereign state on Mainland China, while the Kuomintang-led government retreated to the island of Taiwan. The political status of Taiwan remains disputed. Since the introduction of economic reforms in 1978, China's economy has been one of the world's fastest-growing with annual growth rates above 6 percent. According to the World Bank, China's GDP grew from $150 billion in 1978 to $12.24 trillion by 2017. Since 2010, China has been the world's second-largest economy by nominal GDP and since 2014, the largest economy in the world by purchasing power parity.
China is the world's largest exporter and second-largest importer of goods. China is a recognized nuclear weapons state and has the world's largest standing army and second-largest defense budget; the PRC is a permanent member of the United Nations Security Council as it replaced the ROC in 1971, as well as an active global partner of ASEAN Plus mechanism. China is a leading member of numerous formal and informal multilateral organizations, including the Shanghai Cooperation Organization, WTO, APEC, BRICS, the BCIM, the G20. In recent times, scholars have argued that it will soon be a world superpower, rivaling the United States; the word "China" has been used in English since the 16th century. It is not a word used by the Chinese themselves, it has been traced through Portuguese and Persian back to the Sanskrit word Cīna, used in ancient India."China" appears in Richard Eden's 1555 translation of the 1516 journal of the Portuguese explorer Duarte Barbosa. Barbosa's usage was derived from Persian Chīn, in turn derived from Sanskrit Cīna.
Cīna was first used including the Mahābhārata and the Laws of Manu. In 1655, Martino Martini suggested that the word China is derived from the name of the Qin dynasty. Although this derivation is still given in various sources, it is complicated by the fact that the Sanskrit word appears in pre-Qin literature; the word may have referred to a state such as Yelang. The meaning transferred to China as a whole; the origin of the Sanskrit word is still a matter of debate, according to the Oxford English Dictionary. The official name of the modern state is the "People's Republic of China"; the shorter form is "China" Zhōngguó, from zhōng and guó, a term which developed under the Western Zhou dynasty in reference to its royal demesne. It was applied to the area around Luoyi during the Eastern Zhou and to China's Central Plain before being used as an occasional synonym for the state under the Qing, it was used as a cultural concept to distinguish the Huaxia people from perceived "barbarians". The name Zhongguo is translated as "Middle Kingdom" in English.
Archaeological evidence suggests that early hominids inhabited China between 2.24 million and 250,000 years ago. The hominid fossils of Peking Man, a Homo erectus who used fire, were discovered in a cave at Zhoukoudian near Beijing; the fossilized teeth of Homo sapiens have been discovered in Fuyan Cave in Hunan. Chinese proto-writing existed in Jiahu around 7000 BCE, Damaidi around 6000 BCE, Dadiwan from 5800–5400 BCE, Banpo dating from the 5th millennium BCE; some scholars have suggested. According to Chinese tradition, the first dynasty was the Xia, which emerged around 2100 BCE; the dynasty was considered mythical by historians until scientific excavations found early Bronze Age sites at Erlitou, Henan in 1959. It remains unclear whether these sites are the remains of the Xia dynasty or of another culture from the same period; the succeeding Shang dynasty is the earliest to be confirmed by contemporary records. The Shang ruled the plain of the Yellow River in eastern China from the 17th to the 11th century BCE.

Handan is a prefecture-level city located in the southwest of Hebei province, China. The southernmost prefecture-level city of the province, it borders Xingtai on the north, the provinces of Shanxi on the west, Henan on the south and Shandong on the east. At the 2010 census, its population was 9,174,683 inhabitants whom 2,845,790 lived in the built-up area made of 3 urban districts and Yangyan counties, Shahe City in Xintai municipality being conurbated now. Handan, once well-defended from southern attack by a bend in the Zhang River, was a city of the state of Zhao during the Warring States Period of Chinese history, it was their second capital, after Zhongmu. It has held the name "Handan" since at least the 1st millennium BCE. King Wuling of Zhao turned Zhao into one of the Qin state's most stalwart foes, pioneering the use of walls to secure new frontiers; the city was conquered by the State of Qin after the virtual annexation of Zhao by Qin except for the Dai Commandery. The first emperor of China, Qin Shi Huang was born in Handan, the child of a statesman from the state of Qin and after conquering Zhao he ordered all enemies of his mother to be buried alive.
The conquest of Zhao the Qin siege of Handan, is featured extensively in Chen Kaige's classic film, The Emperor and the Assassin. At the beginning of the Han dynasty, Handan was Liu Bang's base for suppressing Chen Xi's rebellion in 197 and 196 BCE; the town was still regarded as a cultural and commercial centre at the end of the dynasty in the early 3rd century CE. It declined because of the numerous battles that ravaged northern China following the Han Dynasty, but maintained a reputation for its fine Cizhou ware well into the Qing dynasty, it was the birthplace in the 19th century of Yang-style tai chi, one of its five major schools. Though much of Handan's ancient history is no longer visible, it still has some attractions, most derived from Zhao folklore such as the road into which Lin Xiangru, courier of the precious Mr. He's jade, backed in order to let his nemesis Lian Po pass first, as well as the location in which Lian Po begged for Lin Xiangru's forgiveness. Modern-day Congtai Park is located on the site of the historical Zhao court.
Next to Congtai Park is the legendary "Xuebu Qiao", or "Learning to Walk Bridge". Legend has it that a noble from the state of Yan heard of a elegant manner of walking unique to Handan. Arriving in Handan, he spent weeks trying to master the Handan style of walking on a bridge, only to fail. In the process, however, he had forgotten how to walk and had to crawl back to Yan; this story inspired the Chinese expression, 邯郸学步, which means learning something difficult too intensely, thereby forgetting the basics in the process. The nearby Xiangtangshan Caves contain massive Buddha statues carved into the mountainside, some dating to the 6th century. Many of these statues were vandalised by occupying Japanese forces during World War II. Handan was prized by the Japanese invaders for its coal reserves. In 2007, Handan was the location of China's largest bank robbery The population at the 2010 census was 941,427 for the 3 urban districts, 2,845,790 for the built up area and 9,174,683 for the entire Prefecture-level city area of 12,068 km2.
The municipal executive and judiciary are situated in Congtai District, as well as the CPC and Public Security bureaux. Handan has a cold, continental semi-arid climate, with strong monsoonal influence, typical of the North China Plain; the normal monthly daily mean temperature ranges from −0.9 °C in January to 27.3 °C in July, while the annual mean temperature is 14.3 °C. A majority of the normal annual precipitation of 502 mm occurs in August. Handan has witnessed rapid growth over the past 20 years. Industrial growth in the city has focused on transport activities. Handan is a major producer of coal and steel, with Coal mines at Fengfeng providing power for Handan's iron and textile mills. Chemical and cement plants along with other industries benefit. Local agriculture produces maize and eggs. Handan has a growing services sector, with retail and trading making up 40% of the economy; the GDP per capita in Renminbi was estimated at ¥13,449 in 2005. In 2015, the figure was ￥33,554.87. According to a survey by "Global voices China" in February 2013, Handan was one of China's most polluted cities due to heavy industrial outputs.
However the government has made a significant effort to make the city cleanerwhich involved closing down many polluting power plants. It is no longer the most polluted city, according to a 2016 government survey, the number of good air quality days is 189 days, an increase of 135 days compared with 2013. Handan Prefecture is home to the AAAAA tourist attractions Guangfu Ancient City and the Nüwa Imperial Palace. According to Handan government in 2007, 40 ethnic groups were present in Handan. Ethnic minorities represent 50,000 people, among which 48,000 Hui. There are 22 Hui schools and 5 Hui junior high schools in Handan; the most widespread religion in Handan is Chinese folk religion, including Buddhism. In 2013, there were more than 150,000 Catholics in Handan according to the Catholic Church, in the Roman Catholic Diocese of Yongnian. Mother of Grace Cathedral in Daming County was built in 1918; the most recent church was built in 2007. There are 300,000 Protestants; the largest Protestant church is on Qianjin Avenue and was built in 1997.
The oldest church was on Congtai Street and was built in 1920. The churc
Hengshui is a prefecture-level city in southern Hebei province, People's Republic of China, bordering Shandong to the southeast. At the 2010 census its population was 4,340,373 inhabitants whom 522,147 lived in the built-up area made of Taocheng urban district, it is on the Jingjiu Railway. Hengshui High School and Hengshui University are located in Hengshui; the Harrison International Peace Hospital is located in Hengshui. This comprehensive teaching and research hospital was named after Dr. Tillson Harrison, a martyr to the Chinese revolution. Dr. Harrison, a Canadian, died in 1947 while transporting medical supplies; some of this equipment is on display in an exhibition room in the hospital. The hospital uses both traditional Chinese medicine and modern western diagnostic and therapeutic technology; the city is renowned as the centre for inside painting of small snuff bottles. Zhang Rucai was born in Hebei Province and since 1972, he started to learn the art of inside painting. In April 1996, he was conferred the title Master of Chinese Folk Arts & Crafts by UNESCO.
The city has a fascinating museum and exhibition of the art of the inside painter - many complex paintings done on the inside of small snuff bottles as well as special larger pieces of glassware. There is a Buddhist Temple on the outskirts of the city, well worth a visit, as is the bridge in the old part of the city - one of the few remnants of the old town. According to a survey made by "Global voices China" in February 2013, 7 cities in Hebei including Xingtai, Baoding, Langfang and Tangshan, are among China's 10 most polluted cities. Hengshui is the seat of the Catholic Diocese of Hengshui
Tianjin romanized as Tientsin, is a coastal metropolis in northern China and one of the nine national central cities of the People's Republic of China, with a total population of 15,621,200 as of 2016 estimation. Its built-up area, made up of 12 central districts, was home to 12,491,300 inhabitants in 2016 and is the world's 29th-largest agglomeration and 11th-most populous city proper, it is governed as one of the four municipalities under the direct administration of central government of the PRC and is thus under direct administration of the central government. Tianjin borders Hebei Province and Beijing Municipality, bounded to the east by the Bohai Gulf portion of the Yellow Sea. Part of the Bohai Economic Rim, it is the largest coastal city in northern China. In terms of urban population, Tianjin is the fourth largest in China, after Shanghai and Guangzhou. In terms of administrative area population, Tianjin ranks fifth in Mainland China; the walled city of Tianjin was built in 1404. As a treaty port since 1860, Tianjin has been a major gateway to Beijing.
During the Boxer Rebellion the city was the seat of the Tianjin Provisional Government. Under the Qing dynasty and the Republic of China, Tianjin became one of the largest cities in the region. At that time, numerous European-style buildings and mansions were constructed in concessions, many of which are well-preserved today. After the founding of the People's Republic of China, Tianjin suffered a depression due to the policy of the central government and Tangshan earthquake, but recovered from 1990s. Nowadays Tianjin is a dual-core city, with its main urban area located along the Hai River, which connects to the Yellow and Yangtze Rivers via the Grand Canal; as of the end of 2010, around 285 Fortune 500 companies have set up base in Binhai. Since 2010, Tianjin's Yujiapu Financial District has become known as China's Manhattan. Tianjin is the pinyin romanization of the Chinese characters 天津, which mean "Heavenly Ford" or "Ford of Heaven"; the origin of the name is obscure. One folk etymology is that it was an homage to the patriotic Chu poet Qu Yuan, whose "Li Sao" includes the verse "...departing from the Ford of Heaven at dawn...".
Another is that it honors a former name of the Girl, a Chinese constellation recorded under the name Tianjin in the Astronomical Record section of the Book of Sui. A third is; the most common are that it was bestowed by the Yongle Emperor of the Ming, who crossed Tianjin's Gu River on his way south to overthrow his nephew the Jianwen Emperor. The land where Tianjin is located today was created in ancient times by sedimentation of various rivers entering the sea at Bohai Gulf, including the Yellow River, which entered the open sea in this area at one point; the opening of the Grand Canal during the Sui dynasty prompted the development of Tianjin into a trading center. During the Qing dynasty Tianjin was promoted to a prefecture or Zhou in 1725 with Tianjin County established under the prefecture in 1731, it was upgraded to an urban prefecture or Fu before becoming a relay station under the command of the Viceroy of Zhili. In 1856, Chinese soldiers boarded The Arrow, a Chinese-owned ship registered in Hong Kong flying the British flag and suspected of piracy, of being engaged in the opium trade.
They imprisoned them. In response, the British and French sent gunboats under the command of Admiral Sir Michael Seymour to capture the Taku forts near Tianjin in May 1858. At the end of the first part of the Second Opium War in June of the same year, the British and French prevailed, the Treaty of Tientsin were signed, which opened Tianjin to foreign trade; the treaties were ratified by the Xianfeng Emperor in 1860, Tianjin was formally opened to Great Britain and France, thus to the outside world. Between 1895 and 1900, Britain and France were joined by Japan and Russia, by countries without Chinese concessions such as Austria-Hungary and Belgium, in establishing self-contained concessions in Tianjin, each with its own prisons, schools and hospitals; these nations left many architectural reminders of their rule, notably churches and thousands of villas. The presence of foreign influence in Tianjin was not always peaceful. In June 1870, the orphanage held by the Wanghailou Church, in Tianjin, built by French Roman Catholic missionaries, was accused of the kidnapping and brainwashing of Chinese children.
On June 21, the magistrate of Tianjin County initiated a showdown at the church that developed into violent clashes between the church's Christian supporters and non-Christian Tianjin residents. The furious protestors burned down Wanghailou Church and the nearby French consulate and killed eighteen foreigners including ten French nuns, the French consul, merchants. France and six other Western nations complained to the Qing government, forced to pay compensation for the incident. In 1885 Li Hongzhang founded the Tianjin Military Academy for Chinese army officers, with German advisers, as part of his military reforms; the move was supported by Anhui Army commander Zhou Shengchuan. The academy was to serve Anhui Green Standard Army officers. Various practical military and science subjects were taught at the academy; the instructors were Germa
