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

Chinese language
–
Chinese is a group of related, but in many cases mutually unintelligible, language varieties, forming a branch of the Sino-Tibetan language family. Chinese is spoken by the Han majority and many ethnic groups in China. Nearly 1.2 billion people speak some form of Chinese as their first language, the varieties of Chinese are usually described by native speakers as dialects of a single Chinese language, but linguists note that they are as diverse as a language family. The internal diversity of Chinese has been likened to that of the Romance languages, There are between 7 and 13 main regional groups of Chinese, of which the most spoken by far is Mandarin, followed by Wu, Min, and Yue. Most of these groups are mutually unintelligible, although some, like Xiang and certain Southwest Mandarin dialects, may share common terms, all varieties of Chinese are tonal and analytic. Standard Chinese is a form of spoken Chinese based on the Beijing dialect of Mandarin. It is the language of China and Taiwan, as well as one of four official languages of Singapore. It is one of the six languages of the United Nations. The written form of the language, based on the logograms known as Chinese characters, is shared by literate speakers of otherwise unintelligible dialects. Of the other varieties of Chinese, Cantonese is the spoken language and official in Hong Kong and Macau. It is also influential in Guangdong province and much of Guangxi, dialects of Southern Min, part of the Min group, are widely spoken in southern Fujian, with notable variants also spoken in neighboring Taiwan and in Southeast Asia. Hakka also has a diaspora in Taiwan and southeast Asia. Shanghainese and other Wu varieties are prominent in the lower Yangtze region of eastern China, Chinese can be traced back to a hypothetical Sino-Tibetan proto-language. The first written records appeared over 3,000 years ago during the Shang dynasty, as the language evolved over this period, the various local varieties became mutually unintelligible. In reaction, central governments have sought to promulgate a unified standard. Difficulties have included the great diversity of the languages, the lack of inflection in many of them, in addition, many of the smaller languages are spoken in mountainous areas that are difficult to reach, and are often also sensitive border zones. Without a secure reconstruction of proto-Sino-Tibetan, the structure of the family remains unclear. A top-level branching into Chinese and Tibeto-Burman languages is often assumed, the earliest examples of Chinese are divinatory inscriptions on oracle bones from around 1250 BCE in the late Shang dynasty

Standard Chinese
–
Its pronunciation is based on the Beijing dialect, its vocabulary on the Mandarin dialects, and its grammar is based on written vernacular Chinese. Like other varieties of Chinese, Standard Chinese is a language with topic-prominent organization. It has more initial consonants but fewer vowels, final consonants, Standard Chinese is an analytic language, though with many compound words. There exist two standardised forms of the language, namely Putonghua in Mainland China and Guoyu in Taiwan, aside from a number of differences in pronunciation and vocabulary, Putonghua is written using simplified Chinese characters, while Guoyu is written using traditional Chinese characters. There are many characters that are identical between the two systems, in English, the governments of China and Hong Kong use Putonghua, Putonghua Chinese, Mandarin Chinese, and Mandarin, while those of Taiwan, Singapore, and Malaysia, use Mandarin. The name Putonghua also has a long, albeit unofficial, history and it was used as early as 1906 in writings by Zhu Wenxiong to differentiate a modern, standard Chinese from classical Chinese and other varieties of Chinese. For some linguists of the early 20th century, the Putonghua, or common tongue/speech, was different from the Guoyu. The former was a prestige variety, while the latter was the legal standard. Based on common understandings of the time, the two were, in fact, different, Guoyu was understood as formal vernacular Chinese, which is close to classical Chinese. By contrast, Putonghua was called the speech of the modern man. The use of the term Putonghua by left-leaning intellectuals such as Qu Qiubai, prior to this, the government used both terms interchangeably. In Taiwan, Guoyu continues to be the term for Standard Chinese. The term Putonghua, on the contrary, implies nothing more than the notion of a lingua franca, Huayu, or language of the Chinese nation, originally simply meant Chinese language, and was used in overseas communities to contrast Chinese with foreign languages. Over time, the desire to standardise the variety of Chinese spoken in these communities led to the adoption of the name Huayu to refer to Mandarin and it also incorporates the notion that Mandarin is usually not the national or common language of the areas in which overseas Chinese live. The term Mandarin is a translation of Guānhuà, which referred to the lingua franca of the late Chinese empire, in English, Mandarin may refer to the standard language, the dialect group as a whole, or to historic forms such as the late Imperial lingua franca. The name Modern Standard Mandarin is sometimes used by linguists who wish to distinguish the current state of the language from other northern. Chinese has long had considerable variation, hence prestige dialects have always existed. Confucius, for example, used yǎyán rather than colloquial regional dialects, rime books, which were written since the Northern and Southern dynasties, may also have reflected one or more systems of standard pronunciation during those times

Pinyin
–
Pinyin, or Hànyǔ Pīnyīn, is the official romanization system for Standard Chinese in mainland China, Malaysia, Singapore, and Taiwan. It is often used to teach Standard Chinese, which is 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, and also in certain computer input methods to enter Chinese characters. The pinyin system was developed in the 1950s by many linguists, including Zhou Youguang and it was published by the Chinese government in 1958 and revised several times. The International Organization for Standardization adopted pinyin as a standard in 1982. The system was adopted as the standard in Taiwan in 2009. The word Hànyǔ means the language of the Han people. In 1605, the Jesuit missionary Matteo Ricci published Xizi Qiji in Beijing and this was the first book to use the Roman alphabet to write the Chinese language. Twenty years later, another Jesuit in China, Nicolas Trigault, neither book had much immediate impact on the way in which Chinese thought about their writing system, and 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, 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 effect of the kana syllabaries. 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 actually 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, and it was popular and used in English-language publications outside China until 1979. This Sin Wenz or New Writing was much more sophisticated than earlier alphabets. In 1940, several 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 Societys new journal. Outside the CCP, other prominent supporters included Sun Yat-sens son, Sun Fo, Cai Yuanpei, the countrys most prestigious educator, Tao Xingzhi, an educational reformer. Over thirty journals soon appeared written in Sin Wenz, plus large numbers of translations, biographies, some contemporary Chinese literature, and a spectrum of textbooks

Wu Chinese
–
Wu is a group of linguistically similar and historically related varieties of Chinese primarily spoken in the whole city of Shanghai, Zhejiang province, southern Jiangsu province and bordering areas. Major Wu varieties include those of Shanghai, Suzhou, Ningbo, Wuxi, Wenzhou/Oujiang, Hangzhou, Shaoxing, Jinhua, Wu speakers, such as Chiang Kai-shek, Lu Xun and Cai Yuanpei, occupied positions of great importance in modern Chinese culture and politics. Wu can also be found being used in Shaoxing opera, which is only in national popularity to Peking opera, as well as in the performances of the popular entertainer. Wu is also spoken in a number of diaspora communities, with significant centers of immigration originating from Shanghai, Qingtian. Suzhou has traditionally been the center of Wu and was likely the first place the distinct variety of Sinitic known as Wu developed. Suzhou dialect is considered to be the most linguistically representative of the family. Due to the influence of Shanghainese, Wu as a whole is incorrectly labelled in English as simply, Shanghainese, among speakers of other Sinitic languages, Wu is often subjectively judged to be soft, light, and flowing. There is an idiom in Mandarin that specifically describes these qualities of Wu speech, Ngu nung nioe ngiu, Wu varieties have the largest vowel quality inventories in the world. The Jinhui dialect spoken in Shanghais Fengxian District has 20 vowel qualities, Wu Chinese, along with Min, is also of great significance to historical linguists due to their retention of many ancient features. These two languages have proven pivotal in determining the history of the Chinese languages. More pressing concerns of the present are those of language preservation, however, many analysts believe that a stable state of diglossia will endure for at least several generations if not indefinitely. Saying one speaks Wu is akin to saying one speaks a Romance language and it is not a particularly defined entity like Standard Mandarin or Hochdeutsch. They do this by affixing 話 Wo to their locations endonym, for example, 溫州話 Wēnzhōuhuà is used for Wenzhounese. Affixing 閒話 xiánhuà is also common and more typical of the Taihu division, Wu, the formal name and standard reference in dialectology literature. Northern Wu, Wu typically spoken in the north of Zhejiang and it by default includes the Xuanzhou division in Anhui as well, however this division is often neglected in Northern Wu discussions. Southern Wu, Wu spoken in southern Zhejiang and periphery, comprising the Oujiang, Wuzhou, Western Wu, A term gaining in usage as a synonym for the Xuanzhou division and modeled after the previous two terms since the Xuanzhou division is less representative of Northern Wu. Shanghainese, is also a common name, used because Shanghai is the most well-known city in the Wu-speaking region. The term Shanghainese is never used by linguists to refer to anything

Cantonese
–
Cantonese, or Standard Cantonese, is a variety of Chinese spoken in the city of Guangzhou in southeastern China. It is the prestige variety of Yue, one of the major subdivisions of Chinese. In mainland China, it is the lingua franca of the province of Guangdong and some neighbouring areas such as Guangxi. In Hong Kong and Macau, Cantonese serves as one of their official languages and it is also spoken amongst overseas Chinese in Southeast Asia and throughout the Western World. When Cantonese and the closely related Yuehai dialects are classified together, Cantonese is viewed as vital part of the cultural identity for its native speakers across large swathes of southeastern China, Hong Kong and Macau. Although Cantonese shares some vocabulary with Mandarin, the two varieties are mutually unintelligible because of differences in pronunciation, grammar and lexicon, sentence structure, in particular the placement of verbs, sometimes differs between the two varieties. This results in the situation in which a Cantonese and a Mandarin text may look similar, in English, the term Cantonese is ambiguous. Cantonese proper is the variety native to the city of Canton and this narrow sense may be specified as Canton language or Guangzhou language in English. However, Cantonese may also refer to the branch of Cantonese that contains Cantonese proper as well as Taishanese and Gaoyang. In this article, Cantonese is used for Cantonese proper, historically, speakers called this variety Canton speech or Guangzhou speech, although this term is now seldom used outside mainland China. In Guangdong province, people call it provincial capital speech or plain speech. In Hong Kong and Macau, as well as among overseas Chinese communities, in mainland China, the term Guangdong speech is also increasingly being used among both native and non-native speakers. Due to its status as a prestige dialect among all the dialects of the Cantonese or Yue branch of Chinese varieties, the official languages of Hong Kong are Chinese and English, as defined in the Hong Kong Basic Law. The Chinese language has different varieties, of which Cantonese is one. Given the traditional predominance of Cantonese within Hong Kong, it is the de facto official spoken form of the Chinese language used in the Hong Kong Government and all courts and it is also used as the medium of instruction in schools, alongside English. A similar situation exists in neighboring Macau, where Chinese is an official language along with Portuguese. As in Hong Kong, Cantonese is the predominant spoken variety of Chinese used in life and is thus the official form of Chinese used in the government. The variant spoken in Hong Kong and Macau is known as Hong Kong Cantonese, Cantonese first developed around the port city of Guangzhou in the Pearl River Delta region of southeastern China

Jyutping
–
Jyutping is a romanisation system for Cantonese developed by the Linguistic Society of Hong Kong, an academic group, in 1993. Its formal name is The Linguistic Society of Hong Kong Cantonese Romanisation Scheme, the LSHK promotes the use of this romanisation system. The name Jyutping is a contraction consisting of the first Chinese characters of the terms Jyut6jyu5, only the finals m and ng can be used as standalone nasal syllables. ^ ^ ^ Referring to the pronunciation of these words. There are nine tones in six distinct tone contours in Cantonese, however, as three of the nine are entering tones, which only appear in syllables ending with p, t, and k, they do not have separate tone numbers in Jyutping. Jyutping and the Yale Romanisation of Cantonese represent Cantonese pronunciations with the letters in, The initials, b, p, m, f, d, t, n, l, g, k, ng, h, s, gw, kw. The vowel, aa, a, e, i, o, u, the coda, i, u, m, n, ng, p, t, k. But they differ in the following, The vowels eo and oe represent /ɵ/ and /œː/ respectively in Jyutping, the initial j represents /j/ in Jyutping whereas y is used instead in Yale. The initial z represents /ts/ in Jyutping whereas j is used instead in Yale, the initial c represents /tsʰ/ in Jyutping whereas ch is used instead in Yale. In Jyutping, if no consonant precedes the vowel yu, then the initial j is appended before the vowel, in Yale, the corresponding initial y is never appended before yu under any circumstances. Jyutping defines three finals not in Yale, eu /ɛːu/, em /ɛːm/, and ep /ɛːp/ and these three finals are used in colloquial Cantonese words, such as deu6, lem2, and gep6. To represent tones, only tone numbers are used in Jyutping whereas Yale traditionally uses tone marks together with the letter h. Jyutping and Cantonese Pinyin represent Cantonese pronunciations with the letters in, The initials, b, p, m, f, d, t, n, l, g, k, ng, h, s, gw, kw. The vowel, aa, a, e, i, o, u, the coda, i, u, m, n, ng, p, t, k. But they have differences, The vowel oe represents both /ɵ/ and /œː/ in Cantonese Pinyin whereas eo and oe represent /ɵ/ and /œː/ respectively in Jyutping. The vowel y represents /y/ in Cantonese Pinyin whereas both yu and i are used in Jyutping, the initial dz represents /ts/ in Cantonese Pinyin whereas z is used instead in Jyutping. The initial ts represents /tsʰ/ in Cantonese Pinyin whereas c is used instead in Jyutping. To represent tones, the numbers 1 to 9 are usually used in Cantonese Pinyin, however, only the numbers 1 to 6 are used in Jyutping

Southern Min
–
Southern Min, or Minnan, is a branch of Min Chinese spoken in certain parts of China including southern Fujian, eastern Guangdong, Hainan, and southern Zhejiang, and in Taiwan. The Min Nan dialects are spoken by descendants of emigrants from these areas in diaspora, most notably the Philippines, Indonesia, Malaysia. In common parlance, Southern Min usually refers to Hokkien, including Amoy and Taiwanese Hokkien, the Southern Min dialect group also includes Teochew, though Teochew has limited mutual intelligibility with Hokkien. Hainanese is not mutually intellgible with other Southern Min and is considered a separate branch of Min. Southern Min is not mutually intelligible with Eastern Min, Pu-Xian Min, any other Min branch, Hakka, Cantonese, Shanghainese or Mandarin. Southern Min dialects are spoken in the part of Fujian. The variant spoken in Leizhou, Guangdong as well as Hainan is Hainanese and is not mutually intelligible with other Southern Min or Teochew, Hainanese is classified in some schemes as part of Southern Min and in other schemes as separate. Puxian Min was originally based on the Quanzhou dialect, but over time became heavily influenced by Eastern Min, eventually losing intellegility with Minnan. A forms of Southern Min spoken in Taiwan, collectively known as Taiwanese, Southern Min is a first language for most of the Hoklo people, the main ethnicity of Taiwan. The correspondence between language and ethnicity is not absolute, as some Hoklo have very limited proficiency in Southern Min while some non-Hoklo speak Southern Min fluently, there are many Southern Min speakers also among Overseas Chinese in Southeast Asia. Many ethnic Chinese immigrants to the region were Hoklo from southern Fujian and brought the language to what is now Burma, Indonesia and present-day Malaysia and Singapore. In general, Southern Min from southern Fujian is known as Hokkien, Hokkienese, many Southeast Asian ethnic Chinese also originated in the Chaoshan region of Guangdong and speak Teochew language, the variant of Southern Min from that region. Southern Min-speakers form the majority of Chinese in Singapore, with the largest group being Hokkien, despite the similarities the two groups are rarely seen as part of the same Minnan Chinese subgroups. The variants of Southern Min spoken in Zhejiang province are most akin to that spoken in Quanzhou, the variants spoken in Taiwan are similar to the three Fujian variants and are collectively known as Taiwanese. Those Southern Min variants that are known as Hokkien in Southeast Asia also originate from these variants. The variants of Southern Min in the Chaoshan region of eastern Guangdong province are known as Teochew or Chaozhou. Teochew is of importance in the Southeast Asian Chinese diaspora, particularly in Malaysia, Thailand, Cambodia, Vietnam, Sumatra. The Philippines variant is mostly from the Quanzhou area as most of their forefathers are from the aforementioned area, the Southern Min language variant spoken around Shanwei and Haifeng differs markedly from Teochew and may represent a later migration from Zhangzhou
