It comprises the districts of Ningbo proper, three satellite cities, and a number of rural counties including islands in Hangzhou Bay and the East China Sea. Its port, spread across locations, is among the busiest in the world. As of the 2010 census, the entire administrated area had a population of 7.6 million, with 3.5 million in the six urban districts of Ningbo proper. To the north, Hangzhou Bay separates Ningbo from Shanghai, to the east lies Zhoushan in the East China Sea, on the west and south, Ningbo borders Shaoxing, the first character in the citys name ning means serene, while its second character bo translates to waves. The city is abbreviated Yǒng, after the Yong Hill, a prominent coastal hill near the city, the character ming was composed by two parts, representing two lakes inside the city wall, Sun Lake and Moon Lake. As a city with giant port, culture of Ningbo influences many countries near it, Ningbo is one of Chinas oldest cities, with a history dating to the Hemudu culture in 4800 BC. Since the Tang dynasty Ningbo was an important commercial port, arab traders lived in Ningbo during the Song dynasty when it was known as Mingzhou, as the ocean-going trade passages took precedence over land trade during this time. Another name for Mingzhou/Ningbo was Siming and it was a well known center of ocean-going commerce with the foreign world. These merchants did not intermingle with native Chinese, practicing their own customs and religion and they did not try to proselytize Islam to Chinese. Jews also lived in Ningbo, as evidenced by the fact that, after a flood destroyed Torah scrolls in Kaifeng. The city of Ningbo was known in Europe for a time under the name of Liampó. This is the spelling used e. g. in the standard Portuguese history, João de Barross Décadas da Ásia. The spelling Liampó is also attested in the Peregrination by Fernão Mendes Pinto, for the mid-16th-century Portuguese, the nearby promontory, which they called the cape of Liampó, after the nearby illustrious city was the easternmost known point of the mainland Asia. The Portuguese began trading in Ningbo around 1522, by 1542, the Portuguese had a sizable community in Ningbo. Portuguese activities from their Ningbo base included pillaging and attacking multiple Chinese port cities around Ningbo for plunder and they also enslaved people during their raids. The Portuguese were ousted from the Ningbo area in 1548, Ningbo was one of the five Chinese treaty ports opened by the Treaty of Nanjing at the end of the First Opium War between Britain and China. During the war, British forces took possession of the city of Ningbo briefly after storming the fortified town of Zhenhai at the mouth of the Yong River on October 10,1841

Zhoushan
–
Zhoushan, formerly romanized as Chusan, is a prefecture-level city in northeastern Zhejiang Province in eastern China. It consists of an archipelago of islands at the mouth of Hangzhou Bay. The prefectures city proper is Dinghai on Zhoushan Island, now administered as the prefectures Dinghai District, during the 2010 census, Zhoushan Prefectures population was 1,121,261, out of whom 842,989 lived in the urban districts of Dinghai and Putuo. On 8 July 2011 the central government approved Zhoushan as Zhoushan Archipelago New Area, the archipelago was inhabited 6,000 years ago during the Neolithic by people of the Hemudu culture. During the Spring and Autumn period, Zhoushan was called Yongdong, referring to its location east of the Yong River, at the time, it belonged to the state of Yue. The fishermen and sailors who inhabited the islands often engaged in piracy, at the time of the Eastern Jin, the Zhoushan Islands served as the base for Sun Ens rebellion. Sun En, an adherent of the Taoist sect the Way of the Five Pecks of Rice, todays Zhoushan was first created as Wengshan County in Ming Prefecture in 738 under the Tang. In 863, the Japanese Buddhist monk Egaku and a Putuoshan local Zhang-shi placed a statue of Guanyin at Chaoyin Cave that would become a popular tourist. In 1073, under the Song, it was renamed Changguo County, after suppression of the pirates, Zhoushan became an important commercial entrepôt. Under the early Qing dynasty, it played a role to Xiamen. Changguo Prefecture became Dinghai County within Zhejiang Province in 1688 under the Qing, the restriction of all European trade to the port of Guangzhou in 1760 forced Westerners to leave Zhoushan. The Qianlong Emperor denied this request together with all the rest, at that time, Zhoushan was a well known port while Hong Kong was still only a fishing village. The British Foreign Secretary Palmerston was famously livid when he learned that Elliot agreed to the cession of Hong Kong while giving up Zhoushan, Elliot was dismissed in April 1841 for his blunder. His replacement Sir Henry Pottinger led a British fleet that recaptured Zhoushan on 1 October 1841, as a result, Britain no longer had any use for Zhoushan but it kept the island until 1846 as a guarantee for the fulfilment of the stipulations of the treaty. Dinghai was upgraded to a directly-controlled subprefecture sometime in 1841, Zhoushan was also occupied by the British in 1860 during the Second Opium War. Wang Yijun, a leader of the Taiping rebels, attempted to retake Zhoushan from its Qing garrison on 13 February 1862 but was defeated and killed, following the Xinhai Revolution and the establishment of the Republic of China, Dinghai Subprefecture reverted to a county. Sun Yat-sen visited Zhoushan on 25 August 1916 and wrote Travelling to Putuo. On 1 October 1942, the Japanese ship Lisbon Maru was transporting 1,800 POWs to Tokyo when she was attacked by the USS Grouper off Qingbing or Dongfu, one torpedo hit, the fishermen of nearby Dongji rescued 384 of the British prisoners from the wreckage

Zhejiang
–
Zhejiang, formerly romanized as Chekiang, is an eastern coastal province of China. The provinces name derives from the Zhe River, the name of the Qiantang River which flows past Hangzhou. Kuahuqiao culture was a neolithic culture that flourished in Hangzhou area in 6. Zhejiang was the site of the Neolithic cultures of the Hemudu, the area of modern Zhejiang was outside the major sphere of influence of the Shang civilization during the second millennium BC. Instead, this area was populated by peoples known as Dongyue. The kingdom of Yue began to appear in the chronicles and records written during the Spring, according to the chronicles, the kingdom of Yue was in northern Zhejiang. Shiji claims that its leaders were descended from the Shang founder Yu the Great, the Song of the Yue Boatman was transliterated into Chinese and recorded by authors in north China or inland China of Hebei and Henan around 528 BC. The song shows that the Yue people spoke a language that was mutually unintelligible with the dialects spoken in north, the Sword of Goujian bears bird-worm seal script. Yuenü was a swordswoman from the state of Yue, to check the growth of the kingdom of Wu, Chu pursued a policy of strengthening Yue. Under King Goujian, Yue recovered from its early reverses and fully annexed the lands of its rival in 473 BC, the Yue kings then moved their capital center from their original home around Mount Kuaiji in present-day Shaoxing to the former Wu capital at present-day Suzhou. With no southern power to turn against Yue, Chu opposed it directly and, in 333 BC, yues former lands were annexed by the Qin Empire in 222 BC and organized into a commandery named for Kuaiji in Zhejiang but initially headquartered in Wu in Jiangsu. Kuaiji Commandery was the power base for Xiang Liang and Xiang Yus rebellion against the Qin Empire which initially succeeded in restoring the kingdom of Chu. At the beginning of the Three Kingdoms era, Zhejiang was home to the warlords Yan Baihu and Wang Lang prior to their defeat by Sun Ce and Sun Quan, who eventually established the Kingdom of Wu. Despite the removal of their court from Kuaiji to Jianye, they continued development of the region, industrial kilns were established and trade reached as far as Manchuria and Funan. Zhejiang was part of the Wu during the Three Kingdoms, Wu, commonly known as Eastern Wu or Sun Wu, had been the economically most developed state among the Three Kingdoms. The historical novel Romance of the Three Kingdoms records that Zhejiang had the best-equipped, the story depicts how the states of Wei and Shu, lack of material resources, avoided direct confrontation with the Wu. In armed military conflicts with Wu, the two states relied intensively on tactics of camouflage and deception to steal Wus military resources including arrows and bows, the other two centers in the south were Jiankang and Chengdu. In 589, Qiantang was raised in status and renamed Hangzhou, some may have lost social privilege, and took refugee in areas south to Yangtze River

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

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

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

Quanzhou
–
Quanzhou, formerly known as Chinchew, is a prefecture-level city beside the Taiwan Strait in Fujian Province, China. Its is Fujians largest metropolitan region, with an area of 11,245 square kilometers and, as of the 2010 census, Quanzhou was Chinas 12th-largest extended metropolitan area in 2010. Quanzhou was Chinas major port for foreign traders, who knew it as Zaiton and it was visited by both Marco Polo and Ibn Battuta, both travelers praised it as one of the most prosperous and glorious cities in the world. A failed revolt prompted a massacre of the foreign communities in 1357. Quanzhou became a center in the 19th century but the siltation of its harbor long reduced its capacity for trade by larger ships. Quanzhou is the pinyin romanization of the citys Chinese name 泉州. The name derives from the former status as the seat of the imperial Chinese Quan Prefecture. The romanization Chuan-chiu, Choan-Chiu, and Shanju reflect the local Hokkien pronunciation Choâⁿ-chiu and it is uncertain when or why British sailors first applied the name to Quanzhou. Variants include Kangiu, Chinchu, and Chincheu, variant transcriptions from the Arabic name include Caiton, Çaiton, Çayton, Zaytún, Zaitûn, Zaitún, and Zaitūn. The common folk etymology of satin as deriving from Zaiton cloth seems, however, Quanzhou proper lies on a spit of land between the estuaries of the Jin and Luo rivers as they flow into Quanzhou Bay on the Taiwan Strait. Its surrounding prefecture extends west halfway across the province and is hilly, along with Xiamen and Zhangzhou to its south and Putian to its north, it makes up Fujian Provinces Southern Coast region. In its mountainous interior, it borders Longyan to the southwest and its moderate temperature ranges from 0 to 38 degrees Celsius. In summer, there are typhoons that bring rain and some damage to the city, wang Guoqing used the area as a base of operations for the Chen State before he was subdued by the Sui general Yang Su in the AD 590s. Quanzhou proper was established under the Tang in 718 on a spit of land between two branches of the Jin River, Muslim traders reached the city early on in its existence, along with their existing trade at Guangzhou and Yangzhou. Already connected to inland Fujian by roads and canals, Quanzhou grew to importance in the first century of the Song. A1095 inscription records two convoys, each of twenty ships, arriving from the Southern Seas each year, Quanzhous maritime trade developed the areas ceramics, sugar, alcohol, and salt industries. 90% of Fujians ceramic production at the time was jade-colored celadon, frankincense was such a coveted import that promotions for the trade superintendents at Guangzhou and Quanzhou were tied to the amount they were able to bring in during their terms in office. During this period it was one of the worlds largest and most cosmopolitan seaports, by 1120, its prefecture claimed a population of around 500,000

First Opium War
–
European silver flowed into China when the Canton System, instituted in the mid-18th century, confined the sea trade to Canton and to the Chinese merchants of the Thirteen Factories. The British East India Company had a monopoly of British trade. The British East India Company began to auction opium grown on its plantations in India to independent foreign traders in exchange for silver, the opium was then transported to the Chinese coast and sold to local middlemen who retailed the drug inside China. This reverse flow of silver and the numbers of opium addicts alarmed Chinese officials. In 1839, the Daoguang Emperor, rejecting proposals to legalise and tax opium, Lin confiscated around 20,000 chests of opium without offering compensation, blockaded trade, and confined foreign merchants to their quarters. The failure of the treaty to satisfy British goals of improved trade, in China, the war is considered the beginning of modern Chinese history. Direct maritime trade between Europe and China began in 1557 when the Portuguese leased an outpost at Macau, after the Spanish conquest of the Philippines, the exchange of goods between China and western Europe accelerated dramatically. From 1565, the annual Manila Galleon brought in enormous amounts of silver to the Asian trade network, from 1700–1842, Guangzhou came to dominate maritime trade with China, and this period became known as the Canton System. Official British trade was conducted through the auspices of the British East India Company, the British East India Company gradually came to dominate Sino-European trade from its position in India. From the inception of the Canton System in 1757, trade in goods from China was extremely lucrative for European, however, foreign traders were only permitted to do business through a body of Chinese merchants known as the Cohong and were restricted to Canton. Foreigners could only live in one of the Thirteen Factories, near Shameen Island, while silk and porcelain drove trade through their popularity in the west, an insatiable demand for tea existed in Britain. However, only silver was accepted in payment by China, which resulted in a trade deficit. From the mid-17th century around 28 million kilograms of silver were received by China, principally from European powers, Britain had been on the gold standard since the 18th century, so it had to purchase silver from continental Europe and Mexico to supply the Chinese appetite for silver. Attempts by a British embassy, a Dutch mission, Russias Golovkin in 1805, by 1817, the British realized they could reduce the trade deficit as well as turn the Indian colony profitable by counter-trading in narcotic Indian opium. Opium was produced in traditionally cotton-growing regions of India under British East India Company monopoly, both areas had been hard hit by the introduction of factory-produced cotton cloth, which used cotton grown in Egypt. The opium was auctioned in Calcutta on the condition that it be shipped by British traders to China, Opium as a medicinal ingredient was documented in texts as early as the Tang dynasty but its recreational use was limited and there were laws against its abuse. British sales of opium began in 1781, and sales increased fivefold between 1821 and 1837, by 1820, just when the Qing treasury needed to finance the suppression of rebellions, the flow of silver had reversed, Chinese merchants were now exporting it to pay for opium. The imperial court debated whether or how to end the opium trade, Napier was instructed to obey Chinese regulations, communicate directly with Chinese authorities, superintend trade pertaining to the contraband trade of opium, and to survey Chinas coastline

Port of Shanghai
–
The Port of Shanghai, located in the vicinity of Shanghai, comprises a deep-sea port and a river port. In 2010, Shanghai port overtook the Port of Singapore to become the worlds busiest container port, Shanghais port handled 29.05 million TEUs, whereas Singapores was a half million TEUs behind. In 2016, Shanghai port set a record by handling over 37 million TEUs. The Port of Shanghai faces the East China Sea to the east and it includes the confluences of the Yangtze River, Huangpu River, and Qiantang River. The Port of Shanghai is managed by Shanghai International Port which superseded the Shanghai Port Authority in 2003, Shanghai International Port Company Limited is a public listed company, of which the Shanghai Municipal Government owns 44.23 percent of the outstanding shares. During the Ming dynasty, what is now the city of Shanghai was a part of Jiangsu Province, while Shanghai had become a county seat in the Yuan dynasty, it remained relatively a small town. Its location at the mouth of the Yangtze River led to its development as coastal trade developed during the reign of the Qianlong Emperor in the Qing dynasty. Gradually, the port of Shanghai surpassed the port of Ningbo, in 1842, Shanghai became a treaty port, thus developing into an international commercial city. By the early 20th century, it was the largest city in the Far East, in 1949, with the Communist takeover in Shanghai, overseas trade was cut dramatically. The economic policy of the Peoples Republic had an effect on Shanghais infrastructure. In 1991, the government allowed Shanghai to initiate economic reform. Since then, the port of Shanghai has developed at an increasing pace, by 2005, the Yangshan deep water port was built on the Yangshan islands, a group of islands in Hangzhou Bay, linked to Shanghai by the Donghai Bridge. This development allowed the port to overcome shallow water conditions in its current location, and to rival another deep-water port and it serves the Yangtze economically developed hinterland of Anhui, Jiangsu, Zhejiang and Henan provinces with its dense population, strong industrial base and developed agricultural sector.

Estuary
–
An estuary is a partially enclosed coastal body of brackish water with one or more rivers or streams flowing into it, and with a free connection to the open sea. Estuaries form a zone between river environments and maritime environments. They are subject both to marine influences—such as tides, waves, and the influx of saline water—and to riverine influences—such as flows of fresh water and sediment. The inflows of sea water and fresh water provide high levels of nutrients both in the water column and in sediment, making estuaries among the most productive natural habitats in the world. Most existing estuaries formed during the Holocene epoch with the flooding of river-eroded or glacially scoured valleys when the sea began to rise about 10. Estuaries are typically classified according to their geomorphological features or to water-circulation patterns, the banks of many estuaries are amongst the most heavily populated areas of the world, with about 60% of the worlds population living along estuaries and the coast. The word estuary is derived from the Latin word aestuarium meaning tidal inlet of the sea, there have been many definitions proposed to describe an estuary. However, this definition excludes a number of water bodies such as coastal lagoons. This broad definition also includes fjords, lagoons, river mouths, an estuary is a dynamic ecosystem having a connection to the open sea through which the sea water enters with the rhythm of the tides. The sea water entering the estuary is diluted by the water flowing from rivers. The pattern of dilution varies between different estuaries and depends on the volume of water, the tidal range. Drowned river valleys are known as coastal plain estuaries. In places where the sea level is rising relative to the land, sea water progressively penetrates into river valleys and this is the most common type of estuary in temperate climates. Well-studied estuaries include the Severn Estuary in the United Kingdom and the Ems Dollard along the Dutch-German border, the width-to-depth ratio of these estuaries is typically large, appearing wedge-shaped in the inner part and broadening and deepening seaward. Water depths rarely exceed 30 m, examples of this type of estuary in the U. S. are the Hudson River, Chesapeake Bay, and Delaware Bay along the Mid-Atlantic coast, and Galveston Bay and Tampa Bay along the Gulf Coast. They are relatively common in tropical and subtropical locations and these estuaries are semi-isolated from ocean waters by barrier beaches. Formation of barrier beaches partially encloses the estuary, with only narrow inlets allowing contact with the ocean waters, bar-built estuaries typically develop on gently sloping plains located along tectonically stable edges of continents and marginal sea coasts. They are extensive along the Atlantic and Gulf coasts of the U. S. in areas with active coastal deposition of sediments, barrier beaches form in shallow water and are generally parallel to the shoreline, resulting in long, narrow estuaries

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
