Prefecture-level city
–
Prefectural level cities form the second level of the administrative structure. Administrative chiefs of prefectural level cities generally have the rank as a division chief of a national ministry. Since the 1980s, most former prefectures have been renamed into prefectural level cities, a prefectural level city is a city and prefecture that have been merged into one unified jurisdiction. The larger prefectural level cities span over 100 kilometres, prefectural level cities nearly always contain multiple counties, county level cities, and other such sub-divisions. To distinguish a prefectural level city from its urban area. The first prefectural level cities were created on 5 November 1983, over the following two decades, prefectural level cities have come to replace the vast majority of Chinese prefectures, the process is still ongoing. Most provinces are composed entirely or nearly entirely of prefectural level cities, shijiazhuang and Zhengzhou are the largest prefectural level cities with populations approaching or exceeding some sub-provincial cities. A sub-prefecture-level city is a city with powers approaching those of prefectural level cities. There are total of three classification of prefecture-level city, Regular prefectural level city which consist of counties, county level cities, consolidated district-governed prefectural level city which only consist of districts as it subdivisions. Thus, Bloomington, Indiana is indicated on the map by a point, which is distinct from, and enclosed by, in China, however, large cities such as City of Xianning may, in reality, contain both urban and rural elements. Moreover, they may enclose counties or other cities, on a less detailed map, City of Xianning would be indicated by a point, more or less corresponding to the coordinates of its city government. Other populous areas may also be exhibited as points, such as County of Tongshan, with no indication that County of Tongshan is, in fact, enclosed by City of Xianning. On a more detailed map, City of Xianning would be drawn as an area, similar to a county of the United States and this convention may lead to difficulty in the identification of places mentioned in older sources. For example, Guo Moruo writes that he was born in Town of Shawan, within Prefecture of Leshan, and attended primary school in Town of Jiading. A modern map is unlikely to show either town, Shawan, because it is too small, and Jiading, because it is the seat of City of Leshan, and is therefore indicated on the map by a point labelled Leshan. A more detailed map would show Shawan as a district within City of Leshan, statistics of China such as population and industrial activity are generally reported along prefectural city lines. Thus, the relatively unknown City of Huangshi has 2.5 million residents, more than most European capitals, but upon closer inspection, furthermore, Huangshi contains several other cities, such as City of Daye. If a person wished to calculate the population of the area of Huangshi, and had a map of Huangshi, and a table of its population by district

Geographic coordinate system
–
A geographic coordinate system is a coordinate system used in geography that enables every location on Earth to be specified by a set of numbers, letters or symbols. The coordinates are chosen such that one of the numbers represents a vertical position. A common choice of coordinates is latitude, longitude and elevation, to specify a location on a two-dimensional map requires a map projection. The invention of a coordinate system is generally credited to Eratosthenes of Cyrene. Ptolemy credited him with the adoption of longitude and latitude. Ptolemys 2nd-century Geography used the prime meridian but measured latitude from the equator instead. Mathematical cartography resumed in Europe following Maximus Planudes recovery of Ptolemys text a little before 1300, in 1884, the United States hosted the International Meridian Conference, attended by representatives from twenty-five nations. Twenty-two of them agreed to adopt the longitude of the Royal Observatory in Greenwich, the Dominican Republic voted against the motion, while France and Brazil abstained. France adopted Greenwich Mean Time in place of local determinations by the Paris Observatory in 1911, the latitude of a point on Earths surface is the angle between the equatorial plane and the straight line that passes through that point and through the center of the Earth. Lines joining points of the same latitude trace circles on the surface of Earth called parallels, as they are parallel to the equator, the north pole is 90° N, the south pole is 90° S. The 0° parallel of latitude is designated the equator, the plane of all geographic coordinate systems. The equator divides the globe into Northern and Southern Hemispheres, the longitude of a point on Earths surface is the angle east or west of a reference meridian to another meridian that passes through that point. All meridians are halves of great ellipses, which converge at the north and south poles, the prime meridian determines the proper Eastern and Western Hemispheres, although maps often divide these hemispheres further west in order to keep the Old World on a single side. The antipodal meridian of Greenwich is both 180°W and 180°E, the combination of these two components specifies the position of any location on the surface of Earth, without consideration of altitude or depth. The grid formed by lines of latitude and longitude is known as a graticule, the origin/zero point of this system is located in the Gulf of Guinea about 625 km south of Tema, Ghana. To completely specify a location of a feature on, in, or above Earth. Earth is not a sphere, but a shape approximating a biaxial ellipsoid. It is nearly spherical, but has an equatorial bulge making the radius at the equator about 0. 3% larger than the radius measured through the poles, the shorter axis approximately coincides with the axis of rotation

Provinces of China
–
Provinces, formally provincial-level administrative divisions or first-level administrative divisions, are the highest-level Chinese administrative divisions. There are 34 such divisions, classified as 23 provinces, four municipalities, five autonomous regions, the Peoples Republic of China claims sovereignty over the territory administered by the Republic of China, claiming most of it as its Taiwan Province. The ROC also administers some offshore islands which form Fujian Province and these were part of an originally unified Fujian province, which since the stalemate of the Chinese Civil War in 1949 has been divided between the PRC and ROC. Note that every province has a Communist Party of China provincial committee, the committee secretary is in effective charge of the province, rather than the nominal governor of the provincial government. The government of each province is nominally led by a provincial committee. The committee secretary is first-in-charge of the province, second-in-command is the governor of the provincial government, the Peoples Republic of China claims the island of Taiwan and its surrounding islets, including Penghu, as Taiwan Province. The territory is controlled by the Republic of China, a municipality or direct-controlled municipality is a higher level of city which is directly under the Chinese government, with status equal to that of the provinces. In practice, their status is higher than that of common provinces. The governor of each region is usually appointed from the respective minority ethnic group. A special administrative region is an autonomous and self-governing subnational subject of the Peoples Republic of China that is directly under the Central Peoples Government. Each SAR has an executive as head of the region. The regions government is not fully independent, as policy and military defence are the responsibility of the central government. Notes,1, as of 20102, per km23, km24, Abbreviation in the parentheses is informal 5, Since founding in 1949, however, the PRC has never controlled Taiwan. Taiwan currently administers Taiwan, Penghu, Kinmen and Matsu, the subject of whether or not Taiwan is part of China is often debated, with no clear conclusion. The Ming Dynasty kept the system set up by the Yuan Dynasty, however. By the time of the establishment of the Qing Dynasty in 1644 there were 18 provinces, in addition, there was a zongdu, a general military inspector or governor general, for every two to three provinces. Outer regions of China were not divided into provinces, military leaders or generals oversaw Manchuria, Xinjiang, and Mongolia, while vice-dutong and civilian leaders headed the leagues, a subdivision of Mongolia. The ambans supervised the administration of Tibet, in 1884 Xinjiang became a province, in 1907 Fengtian, Jilin, and Heilongjiang were made provinces as well

Henan
–
Henan is a province of the Peoples Republic of China, located in the central part of the country. Its one-character abbreviation is 豫, named after Yuzhou, a Han Dynasty state that parts of Henan. Although the name of the province south of the river, approximately a quarter of the province lies north of the Yellow River. Henan is often referred to as Zhongyuan or Zhongzhou which literally means central plain land or midland, although the name is also applied to the entirety of China proper. Henan is the birthplace of Chinese civilization with over 3,000 years of recorded history, and remained Chinas cultural, economical, numerous heritages have been left behind including the ruins of Shang Dynasty capital city Yin and the Shaolin Temple. Four of the Eight Great Ancient Capitals of China, Luoyang, Anyang, Kaifeng, with an area of 167,000 km2, Henan covers a large part of the fertile and densely populated North China Plain. Its neighbouring provinces are Shaanxi, Shanxi, Hebei, Shandong, Anhui, Henan is Chinas third most populous province with a population of over 94 million. If it were a country by itself, Henan would be the 12th most populous country in the world, behind Mexico, Henan is the 5th largest provincial economy of China and the largest among inland provinces. However, per capita GDP is low compared to eastern and central provinces. The economy continues to depend on its dwindling aluminum and coal reserves, as well as agriculture, heavy industry, tourism, high-tech industry and service sector is underdeveloped and is concentrated around Zhengzhou and Luoyang. Widely regarded as the Cradle of Chinese civilization along with Shanxi and Shaanxi provinces, Henan is known for its historical prosperity, the economic prosperity resulted from its extensive fertile plains and its location at the heart of the country. However, its location also means that it has suffered from nearly all of the major wars in China. In addition, the floods of the Yellow River have caused significant damage from time to time. Kaifeng, in particular, has been buried by the Yellow Rivers silt seven times due to flooding, archaeological sites reveal that prehistoric cultures such as the Yangshao Culture and Longshan Culture were active in what is now northern Henan since the Neolithic Era. The more recent Erlitou culture has been identified with the Xia Dynasty. Virtually the entire kingdom existed within what is now north and central Henan, the Xia Dynasty collapsed around the 16th century BC following the invasion of Shang, a neighboring vassal state centered around todays Shangqiu in eastern Henan. The Shang Dynasty was the first literate dynasty of China and its many capitals are located at the modern cities of Shangqiu, Yanshi, and Zhengzhou. Their last and most important capital, Yin, located in modern Anyang, is where the first Chinese writing was created, in the 11th century BC, the Zhou Dynasty of Shaanxi arrived from the west and overthrew the Shang Dynasty

Metropolitan area
–
As social, economic and political institutions have changed, metropolitan areas have become key economic and political regions. The Greater São Paulo is a term for one of the multiple definitions the large metropolitan area located in the São Paulo state in Brazil. A metropolitan area combines an urban agglomeration with zones not necessarily urban in character and these outlying zones are sometimes known as a commuter belt, and may extend well beyond the urban zone, to other political entities. For example, El Monte, California is considered part of the Los Angeles metro area in the United States, in practice, the parameters of metropolitan areas, in both official and unofficial usage, are not consistent. Population figures given for one area can vary by millions. A polycentric metropolitan area is one not connected by continuous development or conurbation, in defining a metropolitan area, it is sufficient that a city or cities form a nucleus that other areas have a high degree of integration with. The Australian Bureau of Statistics defines statistical divisions as areas under the influence of one or more major towns or a major city. However, this definition has become obsolete with the conurbation of several statistical divisions into a larger metropolitan areas. In Brazil, metropolitan areas are called metropolitan regions, each State defines its own legislation for the creation, definition and organization of a metropolitan region. The creation of a region is not intended for any statistical purpose, although the Brazilian Institute of Geography. Their main purpose is to allow for a management of public policies of common interest to all cities involved. They dont have political, electoral or jurisdictional power whatsoever, so living in a metropolitan region do not elect representatives for them. Statistics Canada defines a metropolitan area as an area consisting of one or more adjacent municipalities situated around a major urban core. To form a CMA, the area must have a population of at least 100,000. To be included in the CMA, adjacent municipalities must have a degree of integration with the core. As of the Canada 2011 Census, there were 33 CMAs in Canada, including six with a population over one million—Toronto, Montreal, Vancouver, Ottawa, Calgary and Edmonton. In Denmark the only area is Greater Copenhagen, consisting of the Capital Region of Denmark along with the neighboring regions Region Zealand. Greater Copenhagen has an population of 1.25 million people

Time in China
–
The time in China follows a single standard time offset of UTC+08,00, despite China spanning five geographical time zones. The official national standard time is called Beijing Time domestically and China Standard Time internationally, daylight saving time has not been observed since 1991. The special administrative regions maintain their own authorities, with standards called Hong Kong Time. These have been equivalent to Beijing time since 1992, in addition, a second time standard is used in Xinjiang, two hours less than the Beijing Time, which is called Ürümqi Time or Xinjiang Time. In 1912, the Republic of China established five standard time zones, namely Kunlun, Sinkiang-Tibet, Kansu-Szechwan, Chungyuan, and Changpai. The unified time zone policy was adopted by the Communist Party of China or the Central People’s Government some time between 27 September 1949 and 6 October 1949, the date is unknown. However, recent research suggests that the policy was most likely adopted on 27 September 1949, daylight saving time was observed from 1986 to 1991. In 1997 and 1999, Hong Kong and Macau were transferred to China from the United Kingdom and Portugal, although the sovereignty of the SARs belongs to China, they retain their own policies regarding time zones for historical reasons. Due to their locations, both are within the UTC+08,00 time zone, which is the same as the national standard — Beijing time. Xinjiang Time, also known as Ürümqi Time, is set due to its location in the westernmost part of the country. The time offset is UTC+06,00, which is two hours behind Beijing, and is shared with neighbouring Kazakhstan and Kyrgyzstan. Currently, timezone usage within Xinjiang is roughly split along the divide, with most ethnic Han following Beijing time. Some local authorities are now using both time standard side by side, the coexistence of two timezones within the same region causes some confusion among the local population, especially when inter-racial communication occur. Some ethnic Han in Xinjiang might not be aware of the existence of the UTC+6 Xinjiang Time because of language barrier, regardless, Beijing Time users in Xinjiang usually schedule their daily activities two hours later than those who live in eastern China. As such, stores and offices in Xinjiang are commonly opening from 10am to 7pm Beijing Time and this is known as the work/rest time in Xinjiang. Hong Kong maintains its own time authority after transfer of sovereignty in 1997, the Hong Kong Time is UTC+08,00 all year round, and daylight saving time has not been used since 1979. Greenwich Mean Time was adopted as the basis in 1904, before that, local time was determined by astronomical observations at Hong Kong Observatory using a 6-inch Lee Equatorial and a 3-inch Transit Circle. Macau maintains its own time authority after transfer of sovereignty in 1999, the Macau Standard Time is the time in Macau
