Jiangsu
–
Jiangsu, formerly romanized as Kiangsu, is an eastern-central coastal province of the Peoples Republic of China. It is one of the provinces in manufacturing electronics and apparel items. Jiangsu is the third smallest, but the fifth most populous, Jiangsu has the second-highest GDP of Chinese provinces, after Guangdong. Jiangsu borders Shandong in the north, Anhui to the west, Jiangsu has a coastline of over 1,000 kilometres along the Yellow Sea, and the Yangtze River passes through the southern part of the province. Since the Sui and Tang dynasties, Jiangsu has been an economic and commercial center. Cities such as Yangzhou, Nanjing, Wuxi, Suzhou and Shanghai are all major Chinese economic hubs, since the initiation of economic reforms in 1990, Jiangsu has become a focal point for economic development. It is widely regarded as Chinas most developed province measured by its Human Development Index, Jiangsu is home to many of the worlds leading exporters of electronic equipment, chemicals and textiles. It has also been Chinas largest recipient of foreign investment since 2006. Its 2014 nominal GDP was more than 1 trillion US dollars and its name is a compound of the first elements of the names of the two cities of Jiangning and Suzhou. The abbreviation for this province is 苏, the character of its name. The state of Wu was subjugated in 473 BC by the state of Yue, Yue was in turn subjugated by the powerful state of Chu from the west in 333 BC. Eventually the state of Qin swept away all the other states, during the Three Kingdoms period, southern Jiangsu became the base of the Eastern Wu whose capital, Jiankang, is modern Nanjing. When nomadic invasions overran northern China in the 4th century, the court of the Jin Dynasty moved to Jiankang. Cities in southern and central Jiangsu swelled with the influx of migrants from the north, Jiankang remained as the capital for four successive Southern Dynasties and became the largest commercial and cultural center in China. The Tang Dynasty relied on southern Jiangsu for annual deliveries of grain and it was during the Song Dynasty, which saw the development of a wealthy mercantile class and emergent market economy in China, that south Jiangsu emerged as a center of trade. From then onwards, south Jiangsu, especially cities like Suzhou or Yangzhou, would be synonymous with opulence. Today south Jiangsu remains one of the richest parts of China, the Mongols took control of China in the thirteenth century. The Ming Dynasty, which was established in 1368 after driving out the Mongols who had occupied China, following a coup by Zhu Di, however, the capital was moved to Beijing, far to the north

Yangzhou
–
Yangzhou, formerly romanized as Yangchow, is a prefecture-level city in central Jiangsu Province, China. Its population was 4,414,681 at the 2010 census and its area is home to 2,146,980 inhabitants. Historically, Yangzhou was one of the wealthiest cities in China, known at various periods for its great merchant families, poets, artists and its name refers to its former position as the capital of the ancient Yangzhou prefecture in imperial China. Currently, the city of Yangzhou administers six county-level divisions. Accordingly, they are divided into 98 township-level divisions, including 87 towns and townships. Guangling, the first settlement in the Yangzhou area, was founded in the Spring, after the defeat of Yue by King Fuchai of Wu, a garrison city was built 12 metres above the water level on the north bank of the Yangtze c.485 BC. This city in the shape of a three by three li square was named Hancheng, the newly built Han canal formed a moat around the south and east sides of the city. The purpose of Hancheng was to protect Suzhou from naval invasion from Qi, in 590, the city began to be called Yangzhou, which was the traditional name of what was the entire southeastern part of China then. Under Emperor Yang of Sui, Yangzhou was the capital of China. It was called Jiangdu upon the completion of the Grand Canal until the fall of the Sui dynasty, as revolts spread across China in 616, the Emperor abandoned the North and meanwhile withdrew to Jiangdu, where he remained until his assassination in 618. The city has remained an economic and cultural center and major port of foreign trade. During the Tang dynasty, many merchants from Silla also lived in Yangzhou, the city, still known as Guangling, was briefly made the capital of Wu during the Five Dynasties and Ten Kingdoms period. Yangzhou was briefly the seat of the Song dynasty government between 1128 and 1129, when most of North China had been conquered by the Jurchens during the Jin–Song Wars. The Song had retreated south to the city from their capital in Kaifeng after it was captured by the Jurchen in the Jingkang Incident of 1127. From Yangzhou, the Song moved to Hangzhou in 1129, later establishing it as the capital of the Southern Song, in 1280, Yangzhou was the site of a massive gunpowder explosion when the bomb store of the Weiyang arsenal accidentally caught fire. This blast killed over a hundred guards, hurled debris from buildings into the air that landed ten li away from the site of the explosion, marco Polo claimed to have served the Yuan dynasty in Yangzhou under Kubilai Khan in the period around 1282–1287. Although some versions of Polos memoirs imply that he was the governor of Yangzhou, it is likely that he was an official in the salt industry. Chinese texts offer no supporting evidence for his claim, there were also Arabic inscriptions from the 13th and 14th centuries, indicating the presence of a Muslim community

Yangtze River Delta
–
The area lies at the heart of the region traditionally called Jiangnan. The Yangtze River drains into the East China Sea, the urban build-up in the area has given rise to what may be the largest concentration of adjacent metropolitan areas in the world. It covers an area of 99,600 square kilometres and is home to over 115 million people as of 2013, if based on the greater Yangtze River Delta zone, it has over 140 million people in this region. Having a fertile soil, the Yangtze River Delta abundantly produces grain, cotton, hemp, Hangzhou served as the Chinese capital during the Southern Song dynasty, and Nanjing was the early capital of the Ming dynasty before the Yongle Emperor moved the capital to Beijing in 1421. Other key cities of the region in pre-modern times include Suzhou, the ancient Suzhou was the capital of the Wu state, and the ancient Shaoxing was the capital of the Yue state. Nanjing first served as a capital in the Three Kingdoms period as the capital of Eastern Wu, in these periods, there were several concomitant states or empires in China and each one had its own capital. The delta is one of the most densely populated regions on earth, most of the people in this region speak Wu Chinese as their mother tongue, in addition to Mandarin. Wu is mutually unintelligible with other varieties of Chinese, including Mandarin, the area of the Yangtze River Delta incorporates more than twenty relatively developed cities in three provinces. The term can be used to refer to the entire region extending as far north as Lianyungang, Jiangsu and as far south as Wenzhou. The region includes some of the economies in China in recent years. Since the ninth century, the Yangtze Delta has been the most populous area in China, East Asia, Ningbo became one of the two biggest seaports in East Asia along with Quanzhou. During the Ming and Qing dynasties, the became a large economic centre for the country. During the Qianlong era of the Qing dynasty, Shanghai began developing rapidly, from late 19th century to early 20th century, Shanghai was the biggest commercial centre in the Far East. The Yangtze River Delta became the first industrialized area in China and it is the centre of Chinese economic development, and surpasses other concentrations of metropolitan areas in China in terms of economic growth, productivity and per capita income. In 1982, the Chinese government set up the Shanghai Economic Area, besides Shanghai, four cities in Jiangsu and five cities in Zhejiang were included. In 1992, a 14-city cooperative joint meeting was launched, besides the previous 10 cities, the members included Nanjing, Zhenjiang and Yangzhou in Jiangsu, and Zhoushan in Zhejiang. In 1997, the joint meeting resulted in the establishment of the Yangtze River Delta Economic Coordination Association. In 2003, Taizhou in Zhejiang also joined the association, in 2010, the association accepted six new members after a six-year observation and review, including Yancheng and Huaian in Jiangsu, Jinhua and Quzhou in Zhejiang, and Maanshan and Hefei in Anhui

Yangtze
–
The Yangtze River, known in China as the Cháng Jiāng or the Yángzǐ Jiāng, is the longest river in Asia and the third-longest in the world. The river is the longest in the world to flow entirely within one country and it drains one-fifth of the land area of the Peoples Republic of China and its river basin is home to one-third of the countrys population. The Yangtze is the sixth-largest river by volume in the world. The Yangtze River plays a role in the history, culture. The prosperous Yangtze River Delta generates as much as 20% of the PRCs GDP, for thousands of years, the river has been used for water, irrigation, sanitation, transportation, industry, boundary-marking and war. The Three Gorges Dam on the Yangtze River is the largest hydro-electric power station in the world, in recent years, the river has suffered from industrial pollution, agricultural run-off, siltation, and loss of wetland and lakes, which exacerbates seasonal flooding. Some sections of the river are now protected as nature reserves, a stretch of the upstream Yangtze flowing through deep gorges in western Yunnan is part of the Three Parallel Rivers of Yunnan Protected Areas, a UNESCO World Heritage Site. In mid-2014 the Chinese government announced it was building a transport network, comprising railways, roads and airports. Because the source of the Yangtze was not ascertained until modern times, Yangtze was actually the name of Chang Jiang for the lower part from Nanjing to the river mouth at Shanghai. In modern Chinese, Yangtze is still used to refer to the part of Chang Jiang from Nanjing to the river mouth. Yangtze never stands for the whole Chang Jiang, Chang Jiang is the modern Chinese name for the lower 2,884 km of the Yangtze from its confluence with the Min River at Yibin in Sichuan Province to the river mouth at Shanghai. Chang Jiang literally means the Long River, in Old Chinese, this stretch of the Yangtze was simply called Jiang/Kiang 江, a character of phono-semantic compound origin, combining the water radical 氵 with the homophone 工. Krong was probably a word in the Austroasiatic language of local peoples such as the Yue, similar to *krong in Proto-Vietnamese and krung in Mon, all meaning river, it is related to modern Vietnamese sông and Khmer kôngkea. By the Han Dynasty, Jiang had come to any river in Chinese. The epithet 長, means long, was first formally applied to the river during the Six Dynasties period, various sections of Chang Jiang have local names. From Yibin to Yichang, the river through Sichuan and Chongqing Municipality is also known as the Chuan Jiang or Sichuan River, in the Hubei Province, the river is also called the Jing Jiang or the Jing River after Jingzhou. In Anhui Province, the takes on the local name Wan Jiang after the shorthand name for Anhui. And Yangzi Jiang t 揚子江s 扬子江, p Yángzǐjiāng) or the Yangzi River, the name likely comes from an ancient ferry crossing called Yangzi or Yangzijin

Grand Canal (China)
–
The Grand Canal, a UNESCO World Heritage Site, is the longest canal or artificial river in the world and a famous tourist destination. Starting at Beijing, it passes through Tianjin and the provinces of Hebei, Shandong, Jiangsu and Zhejiang to the city of Hangzhou, linking the Yellow River and Yangtze River. The oldest parts of the date back to the 5th century BC. The total length of the Grand Canal is 1,776 km and its greatest height is reached in the mountains of Shandong, at a summit of 42 m. The canal has been admired by many throughout history including Japanese monk Ennin, Persian historian Rashid al-Din, Korean official Choe Bu, historically, periodic flooding of the adjacent Yellow River threatened the safety and functioning of the canal. During wartime the high dikes of the Yellow River were sometimes deliberately broken in order to flood advancing enemy troops and this caused disaster and prolonged economic hardships. Despite temporary periods of desolation and disuse, the Grand Canal furthered an indigenous and it has allowed faster trading and has improved Chinas economy. The southern portion remains in constant heavy use to the present day, in the late Spring and Autumn period, King Fuchai of Wu, ruler of the State of Wu, ventured north to conquer the neighboring State of Qi. He ordered a canal be constructed for trading purposes, as well as a means to ship ample supplies north in case his forces should engage the northern states of Song and this canal became known as the Han Gou. Han Gou is known as the second oldest section of the later Grand Canal since the Hong Gou most likely preceded it and it linked the Yellow River near Kaifeng to the Si and Bian rivers and became the model for the shape of the Grand Canal in the north. The exact date of the Hong Gous construction is uncertain, it is first mentioned by the diplomat Su Qin in 330 BC when discussing state boundaries. The historian Sima Qian dated it much earlier than the 4th century BC, attributing it to the work of Yu the Great and its main role throughout its history was the transport of grain to the capital. By the year 600, there were major build ups of silt on the bottom of the Hong Gou canal, obstructing river barges whose drafts were too deep for its waters. The chief engineer of the Sui dynasty, Yuwen Kai, advised the dredging of a new canal that would run parallel to the existing canal, diverging from it at Chenliu. The new canal was to pass not Xuzhou but Suzhou, to connecting with the Si River. With the recorded labor of five men and women under the supervision of Ma Shumou. The Grand Canal was fully completed under the second Sui emperor, from the years 604 to 609, first by linking Luoyang to the Yangzhou, then expanding it to Hangzhou and this allowed the southern area to provide grain to the northern province, particularly to troops stationed there. Running alongside and parallel to the canal was an imperial roadway, the government also planted an enormous line of trees

Xinhai Revolution
–
The Xinhai Revolution, also known as the Revolution of 1911 or the Chinese Revolution, was a revolution that overthrew Chinas last imperial dynasty, and established the Republic of China. The revolution was named Xinhai because it occurred in 1911, the year of the Xinhai stem-branch in the cycle of the Chinese calendar. The revolution consisted of many revolts and uprisings, the turning point was the Wuchang Uprising on October 10,1911, which was the result of the mishandling of the Railway Protection Movement. The revolution arose mainly in response to the decline of the Qing state, many underground anti-Qing groups, with the support of Chinese revolutionaries in exile, tried to overthrow the Qing. The brief civil war that ensued was ended through a compromise between Yuan Shikai, the late Qing military strongman, and Sun Yat-sen, the leader of the Tongmenghui. After the Qing court transferred power to the newly founded republic, October 10 is commemorated in Taiwan as Double Ten Day, the National Day of the ROC. In mainland China, Hong Kong and Macau, the day is usually celebrated as the Anniversary of the Xinhai Revolution. After suffering its first defeat to the West in the First Opium War in 1842, in the wars against the Taiping, Nian, Muslims of Yunnan and the Northwest, the traditional Manchu armies proved themselves incompetent and the court came to rely on local Han armies. Following defeat in the Second Opium War, the Qing tried to modernize by adopting certain Western technologies through the Self-Strengthening Movement from 1861, in 1895, China suffered a serious defeat during the First Sino-Japanese War. This demonstrated that traditional Chinese feudal society also needed to be modernized if the technological and commercial advancements were to succeed. In 1898 the Guangxu Emperor was guided by reformers like Kang Youwei and Liang Qichao for a reform in education, military. The reform was a failure, as it was ended prematurely by a coup led by Empress Dowager Cixi. The Guangxu Emperor, who had always been a dependent on Cixi, was put under house arrest in June 1898. Reformers Kang and Liang would be exiled, while in Canada, in June 1899, they tried to form the Emperor Protection Society in an attempt to restore the emperor. Empress Dowager Cixi mainly controlled the Qing dynasty from this point on, under internal and external pressure, the Qing court began to adopt some of the reforms. The Qing managed to maintain its monopoly on power by suppressing, often with great brutality. Dissidents could operate only in societies and underground organizations, in foreign concessions or in exile overseas. There were many revolutionaries and groups that wanted to overthrow the Qing government to re-establish a Han Chinese government, the earliest revolutionary organizations were founded outside of China, such as Yeung Ku-wans Furen Literary Society, created in Hong Kong in 1890

Song dynasty
–
The Song dynasty was an era of Chinese history that began in 960 and continued until 1279. It succeeded the Five Dynasties and Ten Kingdoms period, coincided with the Liao and Western Xia dynasties and it was the first government in world history to issue banknotes or true paper money nationally and the first Chinese government to establish a permanent standing navy. This dynasty also saw the first known use of gunpowder, as well as the first discernment of true north using a compass, the Song dynasty is divided into two distinct periods, Northern and Southern. During the Northern Song, the Song capital was in the city of Bianjing. The Southern Song refers to the period after the Song lost control of its half to the Jurchen Jin dynasty in the Jin–Song Wars. During this time, the Song court retreated south of the Yangtze, the Southern Song dynasty considerably bolstered its naval strength to defend its waters and land borders and to conduct maritime missions abroad. To repel the Jin, and later the Mongols, the Song developed revolutionary new military technology augmented by the use of gunpowder, in 1234, the Jin dynasty was conquered by the Mongols, who took control of northern China, maintaining uneasy relations with the Southern Song. Möngke Khan, the fourth Great Khan of the Mongol Empire and his younger brother Kublai Khan was proclaimed the new Great Khan, though his claim was only partially recognized by the Mongols in the west. In 1271, Kublai Khan was proclaimed the Emperor of China, after two decades of sporadic warfare, Kublai Khans armies conquered the Song dynasty in 1279. The Mongol invasion led to a reunification under the Yuan dynasty, the population of China doubled in size during the 10th and 11th centuries. The Northern Song census recorded a population of roughly 50 million, much like the Han and this data is found in the Standard Histories. However, it is estimated that the Northern Song had a population of some 100 million people and this dramatic increase of population fomented an economic revolution in pre-modern China. The expansion of the population, growth of cities, and the emergence of a national economy led to the withdrawal of the central government from direct involvement in economic affairs. The lower gentry assumed a role in grassroots administration and local affairs. Appointed officials in county and provincial centers relied upon the gentry for their services, sponsorship. Social life during the Song was vibrant, citizens gathered to view and trade precious artworks, the populace intermingled at public festivals and private clubs, and cities had lively entertainment quarters. The spread of literature and knowledge was enhanced by the expansion of woodblock printing. Technology, science, philosophy, mathematics, and engineering flourished over the course of the Song, although the institution of the civil service examinations had existed since the Sui dynasty, it became much more prominent in the Song period

Qing dynasty
–
It was preceded by the Ming dynasty and succeeded by the Republic of China. The Qing multi-cultural empire lasted almost three centuries and formed the base for the modern Chinese state. The dynasty was founded by the Jurchen Aisin Gioro clan in Manchuria, in the late sixteenth century, Nurhaci, originally a Ming vassal, began organizing Banners, military-social units that included Jurchen, Han Chinese, and Mongol elements. Nurhaci formed the Jurchen clans into an entity, which he renamed as the Manchus. By 1636, his son Hong Taiji began driving Ming forces out of Liaodong and declared a new dynasty, in 1644, peasant rebels led by Li Zicheng conquered the Ming capital, Beijing. The Ten Great Campaigns of the Qianlong Emperor from the 1750s to the 1790s extended Qing control into Central Asia, the early rulers maintained their Manchu ways, and while their title was Emperor, they used khan to the Mongols and they were patrons of Tibetan Buddhism. They governed using Confucian styles and institutions of government and retained the imperial examinations to recruit Han Chinese to work under or in parallel with Manchus. They also adapted the ideals of the system in dealing with neighboring territories. The Qianlong reign saw the apogee and initial decline in prosperity. The population rose to some 400 million, but taxes and government revenues were fixed at a low rate, corruption set in, rebels tested government legitimacy, and ruling elites did not change their mindsets in the face of changes in the world system. Following the Opium War, European powers imposed unequal treaties, free trade, the Taiping Rebellion and the Dungan Revolt in Central Asia led to the deaths of some 20 million people, most of them due to famines caused by war. In spite of disasters, in the Tongzhi Restoration of the 1860s, Han Chinese elites rallied to the defense of the Confucian order. The initial gains in the Self-Strengthening Movement were destroyed in the First Sino-Japanese War of 1895, in which the Qing lost its influence over Korea, New Armies were organized, but the ambitious Hundred Days Reform of 1898 was turned back by Empress Dowager Cixi, a conservative leader. Sun Yat-sen and other revolutionaries competed with reformist monarchists such as Kang Youwei, after the deaths of Cixi and the Guangxu Emperor in 1908, the hardline Manchu court alienated reformers and local elites alike. The Wuchang Uprising on October 11,1911, led to the Xinhai Revolution, General Yuan Shikai negotiated the abdication of Puyi, the last emperor, on February 12,1912. Nurhaci declared himself the Bright Khan of the Later Jin state in both of the 12–13th century Jurchen Jin dynasty and of his Aisin Gioro clan. His son Hong Taiji renamed the dynasty Great Qing in 1636, there are competing explanations on the meaning of Qīng. The character Qīng is composed of water and azure, both associated with the water element and this association would justify the Qing conquest as defeat of fire by water

Paleontology
–
Paleontology or palaeontology is the scientific study of life that existed prior to, and sometimes including, the start of the Holocene Epoch. It includes the study of fossils to determine organisms evolution and interactions with each other, paleontological observations have been documented as far back as the 5th century BC. The science became established in the 18th century as a result of Georges Cuviers work on comparative anatomy, and developed rapidly in the 19th century. The term itself originates from Greek παλαιός, palaios, i. e. old, ancient, ὄν, on, i. e. being, creature and λόγος, logos, i. e. speech, thought, study. Paleontology lies on the border between biology and geology, but differs from archaeology in that it excludes the study of modern humans. It now uses techniques drawn from a range of sciences, including biochemistry, mathematics. The final quarter of the 20th century saw the development of molecular phylogenetics, molecular phylogenetics has also been used to estimate the dates when species diverged, but there is controversy about the reliability of the molecular clock on which such estimates depend. The simplest definition is the study of ancient life, paleontology is one of the historical sciences, along with archaeology, geology, astronomy, cosmology, philology and history itself. This means that it aims to describe phenomena of the past, hence it has three main elements, description of the phenomena, developing a general theory about the causes of various types of change, and applying those theories to specific facts. Sometimes the smoking gun is discovered by an accident during other research. Paleontology lies on the boundary between biology and geology since paleontology focuses on the record of past life but its source of evidence is fossils. In addition paleontology often uses techniques derived from other sciences, including biology, osteology, ecology, chemistry, techniques developed in engineering have been used to analyse how ancient organisms might have worked, for example how fast Tyrannosaurus could move and how powerful its bite was. As knowledge has increased, paleontology has developed specialised subdivisions, vertebrate paleontology concentrates on fossils of vertebrates, from the earliest fish to the immediate ancestors of modern mammals. Invertebrate paleontology deals with fossils of such as molluscs, arthropods. Paleobotany focuses on the study of plants, but traditionally includes the study of fossil algae. Palynology, the study of pollen and spores produced by plants and protists. Micropaleontology deals with all microscopic fossil organisms, regardless of the group to which they belong, one example is the development of oxygenic photosynthesis by bacteria, which hugely increased the productivity and diversity of ecosystems. This also caused the oxygenation of the atmosphere, together, these were a prerequisite for the evolution of the most complex eukaryotic cells, from which all multicellular organisms are built

Google
–
Google is an American multinational technology company specializing in Internet-related services and products. These include online advertising technologies, search, cloud computing, software, Google was founded in 1996 by Larry Page and Sergey Brin while they were Ph. D. students at Stanford University, in California. Together, they own about 14 percent of its shares, and they incorporated Google as a privately held company on September 4,1998. An initial public offering took place on August 19,2004, in August 2015, Google announced plans to reorganize its various interests as a conglomerate called Alphabet Inc. Google, Alphabets leading subsidiary, will continue to be the company for Alphabets Internet interests. Upon completion of the restructure, Sundar Pichai became CEO of Google, replacing Larry Page, rapid growth since incorporation has triggered a chain of products, acquisitions, and partnerships beyond Googles core search engine. The company leads the development of the Android mobile operating system, the Google Chrome web browser, and Chrome OS, the new hardware chief, Rick Osterloh, stated, a lot of the innovation that we want to do now ends up requiring controlling the end-to-end user experience. Google has also experimented with becoming an Internet carrier, alexa, a company that monitors commercial web traffic, lists Google. com as the most visited website in the world. Several other Google services also figure in the top 100 most visited websites, including YouTube, Googles mission statement, from the outset, was to organize the worlds information and make it universally accessible and useful, and its unofficial slogan was Dont be evil. In October 2015, the motto was replaced in the Alphabet corporate code of conduct by the phrase Do the right thing, Google began in January 1996 as a research project by Larry Page and Sergey Brin when they were both PhD students at Stanford University in Stanford, California. They called this new technology PageRank, it determined a websites relevance by the number of pages, and the importance of those pages, Page and Brin originally nicknamed their new search engine BackRub, because the system checked backlinks to estimate the importance of a site. Originally, Google ran under Stanford Universitys website, with the domains google. stanford. edu, the domain name for Google was registered on September 15,1997, and the company was incorporated on September 4,1998. It was based in the garage of a friend in Menlo Park, craig Silverstein, a fellow PhD student at Stanford, was hired as the first employee. The first funding for Google was an August 1998 contribution of $100,000 from Andy Bechtolsheim, co-founder of Sun Microsystems, given before Google was incorporated. At least three other investors invested in 1998, Amazon. com founder Jeff Bezos, Stanford University computer science professor David Cheriton. Author Ken Auletta claims that each invested $250,000, early in 1999, Brin and Page decided they wanted to sell Google to Excite. They went to Excite CEO George Bell and offered to sell it to him for $1 million, vinod Khosla, one of Excites venture capitalists, talked the duo down to $750,000, but Bell still rejected it. Googles initial public offering took place five years later, on August 19,2004, at that time Larry Page, Sergey Brin, and Eric Schmidt agreed to work together at Google for 20 years, until the year 2024

Yellow Sea
–
The Yellow Sea is the name given to the northern part of the East China Sea, which is a marginal sea of the Pacific Ocean. It is located between mainland China and the Korean Peninsula and its name comes from the sand particles from Gobi Desert sand storms that turn the surface of the water golden yellow. The innermost bay of the Yellow Sea is called the Bohai Sea, into it flow both the Yellow River and Hai He. Deposits of sand and silt from those rivers contribute to the sea colour, the northern extension of the Yellow Sea is called the Korea Bay. The Yellow Sea is one of four seas named after common colour terms — the others being the Black Sea, the Red Sea, the International Hydrographic Organization defines the limits of the Yellow Sea as follows, On the South. The parallel of 33°17 North from Saisyu To to the mainland. The Yellow Sea, excluding the Bohai, extends by about 960 km from north to south and about 700 km from east to west, it has an area of about 380,000 km2 and the volume of about 17,000 km3. Its depth is only 44 m on average, with a maximum of 152 m, the sea is a flooded section of continental shelf that formed after the last ice age as sea levels rose 120 m to their current levels. The sea bottom is slowly rising toward China and more rapidly at the Korean Peninsula, the depth gradually increases from north to south. The sea bottom and shores are dominated by sand and silt brought by the rivers through the Bohai Sea and those deposits, together with sand storms are responsible for the yellow water color and the sea name. The area has cold, dry winters with strong northerly monsoons blowing from late November to March, average January temperatures are −10 °C in the north and 3 °C in the south. Summers are wet and warm with frequent typhoons between June and October, air temperatures range between 10 and 28 °C. The average annual precipitation increases from about 500 mm in the north to 1,000 mm in the south, fog is frequent along the coasts, especially in the upwelling cold-water areas. The sea has a warm cyclone current and it is a part of the Kuroshio Current, which diverges near the western part of Japan and flows northward into the Yellow Sea at the speed of below 0.8 km/h. Southward currents prevail near the sea coast, especially in the monsoon period. The water temperature is close to freezing in the part in winter, so drift ice patches and continuous ice fields form. The water temperature and salinity are homogeneous across the depth, the southern waters are warmer at 6–8 °C. In spring and summer, the layer is warmed up by the sun and diluted by the fresh water from rivers, while the deeper water remains cold

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
