83-999: Grand Canal can refer to multiple waterways: Grand Canal (China) in eastern China Grand Canal (Ireland) , between the River Shannon and Dublin in Ireland Grand Canal (Venice) in Venice, Italy Grand Canal d'Alsace in eastern France Grand Canal (Phoenix) in Arizona, United States Grand Canal ( Mario ) , a fictional location appearing in Mario Party 7 GRAND Canal or Great Recycling and Northern Development Canal , proposed for Great Lakes region of North America The proposed Pan Korea Grand Waterway ( 한반도 대운하 ) in South Korea, sometimes referred to as

166-520: A competitor but as an economic feeder into the greater Suzhou market. Therefore, the Grand Canal served to make or break the economic fortunes of certain cities along its route and served as the economic lifeline of indigenous trade within China. The scholar Gu Yanwu of the early Qing dynasty (1644–1912) estimated that the previous Ming dynasty had to employ 47,004 full-time laborers recruited by

249-660: A further canal on the Tonghui River connected Tongzhou with a wharf called the Houhai or "rear sea" in central Beijing. In the Ming and Qing dynasties, however, the water level in the Tonghui River dropped and ships could not travel from Tongzhou to Beijing. Tongzhou then became the northern shipping terminus of the canal. Cargo was unloaded at Tongzhou and transported to Beijing by land. The Tonghui river still exists as

332-524: A gated space while the water could be drained to appropriate levels; the Chinese also built roofed hangars over the space to add further protection for the ships. Much of the Grand Canal was ruined for several years after 1128 when Kaifeng's governor Du Chong ( 杜 充 , Dù Chōng , d.   1141) decided to break the dykes and dams holding back the waters of the Yellow River in order to decimate

415-572: A man named Li Hualong created the Jia Canal. Named after the Jia River whose course it followed, it ran 140 kilometers (87 mi) from Xiazhen (modern Weishan) on the shore of Shandong's Weishan Lake to Suqian in Jiangsu. The construction of the Jia Canal left only 100 kilometers (62 mi) of Yellow River navigation on the Grand Canal, from Suqian to Huai'an, which by 1688 had been removed by

498-559: A rapid courier system. Enormous lines of trees were also planted along parts of the canal as windbreaks. Although the Tang dynasty (618–907) capital at Chang'an was the most thriving metropolis of China in its day, it was the city of Yangzhou —in proximity to the Grand Canal—that was the economic hub of the Tang era. Besides being the headquarters for the government salt monopoly and

581-512: A renovated stone channel, it reaches the city of Linqing on the Shandong – Hebei border. Liangshan County is the northern terminus of the canal for barge traffic. The fifth section of the canal extends for a distance of 524 kilometers (326 mi) from Linqing to Tianjin along the course of the canalized Wei River . Though one of the northernmost sections, its name derives from its position relative to Tianjin. The Wei River at this point

664-419: A series of lakes—Zhaoyang, Dushan, and Nanyang—which nominally form a continuous body of water. At present, diversions of water mean that the lakes are often largely dry land. North of the northernmost Nanyang Lake is the city of Jining . Further on, about 30 km (19 mi) north of Jining, the highest elevation of the canal (38.5 m or 126 ft above sea level) is reached at the town of Nanwang . In

747-495: A smooth and efficient canal system. The city of Kaifeng grew to be a major hub, later becoming the capital of the Song dynasty (960–1279). Although the Tang and Song dynasty international seaports—the greatest being Guangzhou and Quanzhou , respectively—and maritime foreign trade brought merchants great fortune, it was the Grand Canal within China that spurred the greatest amount of economic activity and commercial profit. During

830-467: A total of 165,000 laborers dredged the canal bed in Shandong and built new channels, embankments, and canal locks . The Yongle Emperor moved the Ming capital from Nanjing to Beijing in 1403. This move deprived Nanjing of its status as chief political center of China. The reopening of the Grand Canal also benefited Suzhou over Nanjing since the former was in a better position on the main artery of

913-785: A wide, concrete-lined storm-channel and drain for the suburbs of Beijing. The Eastern Zhejiang Canal runs 239 kilometers (149 mi) across the coastal plain south of Hangzhou Bay in northern Zhejiang. It begins at the Qiantang River in Xixing, Binjiang District , Hangzhou; crosses the Cao'e River in Shaoxing ; and connects to the Yong River and ports on the East China Sea at Ningbo . This Hangzhou–Ningbo canal began as

996-466: Is heavily polluted while drought and industrial water extraction have left it too low to be navigable. The canal, now in Hebei province, passes through the cities of Dezhou and Cangzhou . Although to spectators, the canal appears to be a deep waterway in these city centers, its depth is maintained by weirs and the canal is all but dry where it passes through the surrounding countryside. At its terminus,

1079-530: Is a city of China that is directly affiliated with the central government and is not placed under any provinces. There are four municipalities in China: Beijing , Chongqing , Shanghai , and Tianjin . Although being as a city by name, a Chinese municipality is more than a city in a traditional sense. It is equivalent to a province as it usually composed of a central urban area and a number of much larger surrounding suburban and rural areas. During

1162-856: Is currently navigable. Its course is today divided into seven sections. From south to north these are the Jiangnan Canal, the Li Canal, the Inner Canal, the Middle Canal, the Lu Canal, the South Canal, the North Canal, and the Tonghui River. Man-Made Lake Lianhu Training Lake "Lianhu" was used to feed water to the Grand Canal section near Jiangnan. Since the canal was man-made there was not enough naturally flowing water to keep

1245-550: Is the remnant of the New Nanyang Canal of 1566 – see below). A southerly course passes close by Xuzhou and enters Weishan Lake near Peixian . This latter course is less used today. Canal is utilized by barge traffic bringing coal and construction materials around northern Jiangsu Province. At Weishan Lake, both courses enter Shandong province. From here to Linqing , the canal is called the Lu or 'Shandong' Canal. It crosses

1328-585: The Central Government of the People's Republic of China . After the establishment of the People's Republic of China in 1949, Anshan , Benxi , and Fushun were also made municipalities, while Qingdao, Dalian, and Harbin were reduced to provincial municipalities . Hankou was merged into Wuhan , which became a municipality of its own. Hence, there remained 12 municipalities. In November 1952, Nanjing

1411-737: The Chinese as the Jing – Hang Grand Canal , is thought to extend for 1,776 km (1,104 mi) and is divided into 6 main subsections. The Jiangnan Canal runs from the Qiantang River at Hangzhou to the Yangtze River at Zhenjiang ; the Inner Canal from the Yangtze at Yangzhou to the Huai River at Huai'an , which for centuries was also its junction with the former course of

1494-508: The Chinese government and UNESCO recognized the Eastern Zhejiang Canal from Hangzhou to Ningbo along the former Tongji and Yongji Canals as official components of the Grand Canal. The oldest sections of what is now the Grand Canal were completed in the early 5th century BC during the conflicts of China's Spring and Autumn period to provide supplies and transport routes for the states of Wu and Yue . The network

1577-577: The Huai River , and then transferred back onto deep barges once the shipment of grain reached the Yellow River . Chinese engineers built a dam to divert the Wen River to the southwest in order to feed 60% of its water north into the Grand Canal, with the remainder going south. They dug four large reservoirs in Shandong to regulate water levels, which allowed them to avoid pumping water from local sources and water tables. Between 1411 and 1415

1660-541: The Jiangnan Canal and to connect Luoyang northeast to his wars with Korea by the Yongji Canal ( t 永 濟 渠 , s 永 济 渠 , Yǒngjì Qú ). After this network's completion in 609, Emperor Yang was said to have led a flotilla of boats 105 km (65 mi) long from the north down to his southern capital at Yangzhou. This process again involved massive levies of conscripted labor and

1743-604: The Jiangnan region in the southeast to enrich the main Sui capital at Luoyang to the west and to supply the expeditionary Sui armies in the Goguryeo-Sui Wars to the northeast. The institution of the Grand Canal also obviated the need for army garrisons to become self-sufficient part-time militia-farmers while guarding the dry frontiers between China, Goguryeo and Göktürk .

1826-579: The Ming dynasty and the Manchu Qing dynasty . Despite the importance of railways and roads in modern China, the People's Republic of China has worked to improve the navigability of the canal since the end of the Chinese Civil War and the portion south of the Yellow River remains in heavy use by barges carrying bulk cargo . Increasing concern over pollution in China and particularly

1909-516: The Mongols invaded in the 13th century and began necessary repairs. During the Mongol Yuan dynasty (1271–1368) the capital of China was moved to Beijing, eliminating the need for the canal arm flowing west to Kaifeng or Luoyang. A summit section was dug across the foothills of the Shandong massif during the 1280s, shortening the overall length by as much as 700 km (430 mi), making

1992-692: The Republic of China , the first municipalities were the 11 cities of Nanjing , Shanghai , Beijing , Tianjin , Qingdao , Chongqing , Xi'an , Guangzhou , Hankou (now part of Wuhan ), Shenyang , and Harbin . They were established in 1927 soon after they were designated as "cities" during the 1920s. Nominally, Dalian was a municipality as well, although it was under Japanese control . These cities were first called special municipalities/cities ( 特别市 ; tèbiéshì ), but were later renamed Yuan -controlled municipalities ( 院辖市 ; yuànxiáshì ), then direct-controlled municipalities ( 直辖市 ; zhíxiáshì ) by

2075-604: 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 Canal's construction is uncertain; it is first mentioned by the diplomat Su Qin in 330 BC when discussing state boundaries. The historian Sima Qian (145–90 BC) knew of no historical date for it, placing his discussion of it just after the legendary works of Yu the Great ; modern scholars now consider it to belong to

2158-731: The Song official and engineer Qiao Weiyue invented the pound lock in the 10th century. The canal has been admired by many visitors throughout its history, including the Japanese monk Ennin (794–864), the Persian historian Rashid al-Din Hamadani (1247–1318), the Korean official Choe Bu (1454–1504), and the Italian missionary Matteo Ricci (1552–1610). In the late Spring and Autumn period , King Fuchai of Wu (whose capital

2241-680: The Taiping Rebellion 's Northern Expedition . Because of various factors—the difficulty of crossing the Yellow River, the increased development of an alternative sea route for grain-ships, and the opening of the Tianjin-Pukou Railway and the Beijing-Hankou Railway —the canal languished and for decades the northern and southern parts remained separate. Many of the canal sections fell into disrepair, and some parts were returned to flat fields. Even today,

2324-411: The Tang dynasty while stopover towns along the main course became the economic hubs of the empire. Periodic flooding of the Yellow River threatened the safety and functioning of the canal while, during wartime, the rivers' high dikes were sometimes deliberately broken to delay or sweep away advancing enemy troops. Even so, restoration and improvement of the canal and its associated flood control works

2407-639: The Yangtze Delta to northern China . Minor additions to the canal were made after the Sui period to cut down on travel time, but overall no fundamental differences existed between the Sui Grand Canal and the Tang Grand Canal. By the year 735, it was recorded that about 149,685,400 kilograms (165,000 short tons) of grain were shipped annually along the canal. The Tang government oversaw canal lock efficiency and built granaries along

2490-895: The Yellow River ; the Middle Canal from Huai'an to the Nansi Lakes ; the Lu Canal from the lakes past Jining and the present course of the Yellow River to the Wei River at Linqing ; the Southern Canal from Linqing to the Hai River at Tianjin ; and the Northern Canal from Tianjin to Tongzhou on the outskirts of Beijing. As such, it passes through the provinces and municipalities of Zhejiang , Jiangsu , Shandong , Hebei , Tianjin, and Beijing. In 2014,

2573-434: The greater administrative areas . In June 1954, 11 of the 14 municipalities were reduced to sub-provincial cities; many of them became capitals of the provinces they were in. Only Beijing, Shanghai, and Tianjin remained municipalities, until Chongqing was restored as a municipality in 1997 with a much enlarged area. Tianjin was also temporarily reverted to sub-provincial city status between 1958 and 1967. Municipalities are

It is known that 121,500 soldiers and officers were needed simply to operate the 11,775 government grain barges in the mid-15th century. Besides its function as a grain shipment route and major vein of river-borne indigenous trade in China, the Grand Canal had long been a government-operated courier route as well. In the Ming dynasty, official courier stations were placed at intervals of 35 to 45 km (22 to 28 mi). Each courier station

2822-498: The 1950s a new canal was dug to the south of the old summit section. The old summit section is now dry, while the new canal holds too little water to be navigable. About 50 km (31 mi) further north, passing close by Dongping Lake , the canal reaches the Yellow River. By this point waterless, it no longer connects to the river. It reappears again in Liaocheng City on the north bank where, intermittently flowing through

2905-546: The 1990s, canal barge crews could tell when they neared Hangzhou by the stench of the visibly black water they passed through. Similarly, fishermen on Dongping Lake in Shandong objected to the introduction of water from the Yangtze as part of the South-North Water Diversion Project when they saw it noticeably killing fish and affecting their catch. During the 21st century, increasing efforts have been made to improve environmental conditions along

2988-608: The 6th century BC. The reunification of China under the Sui dynasty (581–618) ended three centuries of chaos since the Upheaval of the Five Barbarians , and the renewed political stability allowed both the thorough repair of existing canals and flood control systems as well as the construction of new canals. The primary consideration of the Sui canals was the need to tap into the expanding economic and agricultural resources of

3071-599: The Beijing–Hangzhou and Sui and Tang canals as part of UNESCO's listing for the Grand Canal. The Grand Canal World Heritage site is composed of 31 sections and a number of accessory heritage sites. Though the canal nominally crosses the watersheds of five river systems, in reality, the variation between these is so low that it has only a single summit section. The elevation of the canal bed varies from 1 m below sea level at Hangzhou to 38.5 m above at its summit. At Beijing, it reaches 27 m, fed by streams flowing downhill from

3154-495: The Chinese architecture. Many saw the canal as an economic advantage that could bring economic prosperity, like the canal and its benefits. Matteo Ricci 's Journals describes the canal in great detail documenting the economic prosperity. The pound lock is one of the more notable features of the Erie canal that is directly connected to the infrastructure of the Grand Canal as it is used in other similar bodies of water. The Grand Canal

3237-765: The Grand Canal from the low-lying and flood-prone land west of Weishan Lake onto the marginally higher land to its east. It was fed by rivers flowing from east to west from the borders of the Shandong massif. North of the Jizhou Canal summit section, the Huitong Canal ran downhill, fed principally by the River Wen, to join the Wei River in the city of Linqing. In 1289, a geological survey preceded its one-year construction. The Huitong Canal, built by an engineer called Ma Zhizhen, ran across sharply sloping ground and

3320-576: The Grand Canal has not fully recovered its importance prior to the floods of the mid-19th century. After the founding of the People's Republic of China in 1949, the need for economic development led the authorities to order heavy reconstruction work. The Grand Canal played a major role during Mao Zedong 's Great Leap Forward as it provided an efficient way to transport grain. It was further refurbished following Deng Xiaoping 's Reform and Opening Up , with improving economic conditions leading to greater infrastructure investment. The economic importance of

3403-476: The Grand Canal with a number of historical sections. Some of these have disappeared, others are still partially extant, and others form the basis for the modern canal. The following are the most important but do not form an exhaustive list. In 12 BC, in order to solve the problem of the Grand Canal having to use 160 kilometers (100 mi) of the perilous course of the Yellow River in Northern Jiangsu,

3486-409: The Grand Canal, and so it became Ming China's greatest economic center. The only other viable contender with Suzhou in the Jiangnan region was Hangzhou, but it was located 200 km (120 mi) further down the Grand Canal and away from the main delta. Even the shipwrecked Korean Choe Bu (1454–1504)—while traveling for five months throughout China in 1488—acknowledged that Hangzhou served not as

3569-573: The Han Canal had connected the Yangtze with the Huai River utilizing existing waterways , lakes , and marshes . The Han Canal is known as the second oldest section of the later Grand Canal since the Hong Canal ( t   鴻溝 , s   鸿沟 , Hónggōu , "Canal of the Wild Geese" or "Far-Flung Canal") most likely preceded it. It linked the Yellow River near Kaifeng to

3652-514: The Jiangnan Canal, the Inner Canal is heavily utilized by barge traffic bringing coal, construction materials and increasingly shipping containers around Jiangsu Province. This 'Middle Canal' section runs from Huai'an to Weishan Lake , passing through Luoma Lake and following more than one course, the result of the impact of centuries of Yellow River flooding. After Pizhou , a northerly course passes through Tai'erzhuang to enter Weishan Lake at Hanzhuang bound for Nanyang and Jining (this course

3735-405: The Jizhou Canal. The Shanyang Canal originally opened onto the Yangtze a short distance south of Yangzhou . As the north shore of the Yangtze gradually silted up to create the sandbank island of Guazhou, it became necessary for boats crossing to and from the Jiangnan Canal to sail the long way around the eastern edge of that island. After a particularly rough crossing of the Yangtze from Zhenjiang,

3818-405: The Shanyin Canal excavated in Shaoxing by the Yue official Fan Li in the early 5th century BC during China's Spring and Autumn period . Despite the difficulty of connecting the route's various watersheds, the present route was completed with the construction of the Xixing Canal by the Jin official He Xun in the late 3rd century AD. The canal was an important artery of transport and supply for

3901-435: The Song and earlier periods, barge ships occasionally crashed and wrecked along the Shanyang Yundao section of the Grand Canal while passing the double slipways, and more often than not those were then robbed of the tax grain by local bandits. This prompted Qiao Weiyue, an Assistant Commissioner of Transport for Huainan , to invent a double-gate system known as the pound lock in the year 984. This allowed ships to wait within

3984-414: The Sui dynasty, Yuwen Kai, advised the digging of a new canal that would run parallel to the existing canal, diverging from it at Chenliu ( Yanzhou ). The new canal was to pass not Xuzhou but Suzhou , to avoid connecting with the Si River and instead make a direct connection with the Huai River just west of Lake Hongze . With the recorded labor of five million people under the supervision of Ma Shumou,

4067-428: The Yellow River flooded and changed its course , severing the course of the canal in Shandong. This was foreseen by a Chinese official in 1447, who remarked that the flood-prone Yellow River made the Grand Canal like a throat that could be easily strangled (leading some officials to request restarting the grain shipments through the East China Sea ). In 1855 the dikes of the canal were opened to flood advancing troops of

4150-415: The Yellow River. Such a case occurred in the year 858 when an enormous flood along the Grand Canal inundated thousands of acres of farmland and killed tens of thousands of people in the North China Plain . Such an unfortunate event could reduce the legitimacy of a ruling dynasty by causing others to perceive it as having lost the Mandate of Heaven ; this was a good reason for dynastic authorities to maintain

4233-441: The Yellow River—overseen by engineer Liang Rui—established canal lock gates to regulate water levels for the canal. Double slipways were installed to haul boats over when the difference in water levels was too great for the flash lock to operate. Similarly, by the year 600, there were major buildups of silt on the bottom of the Hong Canal, obstructing river barges whose drafts were too deep for its waters. The chief engineer of

4316-493: The canal at proper depth so that boats could travel through it. So a man-made lake was used to feed water to the Jiangnan section of the Grand Canal. It was protected by the Government from reclamation and any use of the lake water without proper taxation was deemed illegal. It was supposed to be protected from profitable exploitation, but because the government changed over the years, lake Lianhu had been reclaimed many times and it started to become more shallow. The government changed

4399-416: The canal joins the Hai River in the center of Tianjin City before turning north-west. In Tianjin, the canal heads northwest, for a short time following the course of the Yongding, a tributary of the Hai River , before branching off toward Tongzhou on the edge of the municipality of Beijing. It is here that the modern canal stops and that a Grand Canal Cultural Park has been built. During the Yuan dynasty,

4482-482: The canal will likely continue. The provincial governments of Shandong , Jiangsu , and Zhejiang undertook dredging intended to increase shipping capacity by 40 percent by 2012. The central government has also made the main route of the Grand Canal the eastern path of the South-North Water Diversion Project , using enormous pumping stations to redirect water from the Yangtze Delta to the drier north. The canal became greatly polluted during China's industrialization. By

4565-422: The canal. Around Hangzhou, for instance, a $ 250 million restoration project begun in 2001 improved water quality to the point where it no longer produces a noticeable odor and is once again capable of supporting some fauna. On 22 June 2014, UNESCO 's Conference on World Heritage listed the Grand Canal as a World Heritage Site . As well as its present-day course, fourteen centuries of canal-building have left

4648-471: The cities of Huai'an and Yangzhou . Here the land lying to the west of the canal is higher than its bed while the land to the east is lower. Historically the Shanghe region west of the canal has been prone to frequent flooding, while the Xiahe region to its east has been hit by less frequent but immensely damaging inundations caused by the failure of the Grand Canal levees. Recent works have allowed floodwaters from Shanghe to be diverted safely out to sea. Like

4731-475: The construction of the Middle Canal by Jin Fu. In 1566, to escape the problems caused by flooding of the Yellow River around Yutai (now on the western shore of Weishan Lake), the Nanyang New Canal was opened. It ran for 75 kilometers (47 mi) from Nanyang (now Nanyang Town, located in the center of Weishan Lake) to the small settlement of Liucheng (in the vicinity of modern Gaolou Village, Weishan County, Shandong) north of Xuzhou City. This change in effect moved

4814-416: The first major section of the Grand Canal was completed in the year 605 and was called the Bian Qu. The Grand Canal was fully completed from the years 604 to 609 under Emperor Yang , first by linking his southern capital Yangzhou northwest to Luoyang by the Tongji Canal ( t 通 濟 渠 , s 通 济 渠 , Tōngjì Qú ). He then proceeded to connect Yangzhou southeast to Suzhou and Hangzhou by

4897-406: The high concentration of locks gave it the nicknames chahe or zhahe , i.e. 'the river of locks'. Its great number of feeder springs (between two and four hundred, depending on the counting method and season of the year) also led to it being called the quanhe or 'river of springs'. This, the Grand Canal's first true summit section, was engineered by the Mongol Oqruqči in 1238 to connect Jining to

4980-456: The highest-ranked cities in the PRC. Some cities of lower levels may also refer to themselves as municipalities in the English language . Three levels of cities in the People's Republic of China : In municipalities, the highest ranking government official is the mayor . The mayor is also a delegate in the National People's Congress (the legislature) and deputy secretary of the Chinese Communist Party (CCP) Municipal Committee. However,

5063-467: The lake to become more profitable farmland which led to reclamations and agricultural irrigation using the lake. This began to lead to Lake Lianhu not being able to properly feed water to the Grand Canal. Loss of depth due to reclamation and maintenance costs became too high for the lake to become practical to use. Even though it was a man made lake it was still a beautiful sight. Many different people praised its beauty and various poems have been written about

The Yilou Canal was opened in 738 and still exists, though not as part of the modern Grand Canal route. The Grand Canal nominally runs between Beijing and Hangzhou over a total length of 1,794 km (1,115 mi); however, only the section from Hangzhou to Liangshan County

5478-463: The major cities of Jiaxing , Suzhou , Wuxi , and Changzhou before reaching Zhenjiang . The Jiangnan (or 'South of the Yangtze') Canal is heavily utilized by barge traffic bringing coal, containers and construction materials to the booming delta. It is generally a minimum of 100 meters wide in the congested city centers, and often two or three times this width in the neighboring countryside. In recent years, broad bypass canals have been dug around

5561-446: The major cities to reduce 'traffic jams'. The Suzhou section of the Jiangnan Canal flows through the western part of the city. It includes ten city gates and over 20 stone bridges of traditional design and historic areas that have been well preserved as well as temples and pavilions. The Inner Canal runs between the Yangtze and Huai rivers, skirting the Shaobo , Gaoyou , and Hongze lakes of central Jiangsu. This section connects

It rose to a height of 42 meters (138 ft) above the Yangtze, but environmental and technical factors left it with chronic water shortages until it was re-engineered in 1411 by Song Li of the Ming . Song Li's improvements, recommended by a local man named Bai Ying, included damming the rivers Wen and Guang and drawing lateral canals from them to feed reservoir lakes at

6059-582: The total length about 1,800 km (1,100 mi) and linking Hangzhou and Beijing with a direct north–south waterway for the first time. As in the Song and Jin era, the canal fell into disuse and dilapidation during the Yuan dynasty's decline. The Grand Canal as infrastructure has had influence on other architectural works in the west. The Erie Canal in North America is designed and draws inspiration from

6142-539: The use of the Grand Canal as the eastern path of the South-North Water Diversion Project —intended to provide clean potable water to the north—has led to regulations and several projects to improve water quality along the waterway. The greatest height on the canal is an elevation of 42 m (138 ft) above sea level reached in the foothills of Shandong. Ships in Chinese canals did not have trouble reaching higher elevations after

6225-668: The very summit, at a small town called Nanwang . In AD 369, General Huan Wen of the Eastern Jin dynasty connected the shallow river valleys of the Huai and the Yellow. He achieved this by joining two of these rivers' tributaries, the Si and the Ji respectively, at their closest point, across a low watershed of the Shandong massif. Huan Wen's primitive summit canal became a model for the engineers of

6308-510: Was assigned a different name, all of which were popularized in travel songs of the period. The Manchus invaded China in the mid-17th century, allowed through the northern passes by the Chinese general Wu Sangui once the Ming capital at Beijing had fallen into the hands of a rebel army. The Manchus established the Qing dynasty (1644–1912), and under their leadership, the Grand Canal was overseen and maintained just as in earlier times. In 1855,

6391-484: Was assumed as a duty by each successive dynasty. The canal played a major role in periodically reuniting northern and southern China, and officials in charge of the canal and nearby salt works grew enormously wealthy. Despite damage from floods , rebellions , and wars , the canal's importance only grew with the removal of the capital to Khanbaliq under the Mongol Yuan and to Beijing under Yongle Emperor of

6474-587: Was completed by Emperor Yang of the Sui dynasty in AD 609, linking the fertile Jiangnan region in the south to his capital at Luoyang in the west and to his armies in the far north. His unsuccessful and unpopular wars and the massive amounts of conscripted labor involved in creating the canal were among the chief factors in the rapid fall of the Sui, but the connection of China's major watersheds and population centers proved enormously beneficial. Additional canals supplied Chang'an (now Xi'an ) even further west under

6557-603: Was completed except for areas around Ningbo by 2009, and was fully completed in late 2013. In November 2008, the Eastern Zhejiang Canal was added to the Grand Canal's UNESCO nomination and, in May 2013, was officially included as part of the Grand Canal and listed among the 7th group of Major Historical and Cultural Sites Protected at the National Level by the Chinese government. In 2014, it was included with

6640-622: Was detailed at length in the Record of the Opening of the Canal ( t 《 開 河 記 》 , s 《 开 河 记 》 , Kāihéjì ). At this point, the Grand Canal continued to use noncontiguous artificial channels and both canalized and natural waterways rather than presenting a single continuous manmade canal. However, running alongside and parallel to the course of the canals was an imperial roadway with stables maintained at regular intervals to support

6723-551: Was in present-day Suzhou ), ventured north to attack the State of Qi . He ordered a canal to 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 Lu . This became known as the Han or Hangou Canal ( t 邗溝 , s 邗沟 , Hángōu ). Work began in 486 BC, from south of Yangzhou to north of Huai'an in Jiangsu, and within three years

6806-511: Was reduced to a provincial municipality in Jiangsu . In March 1953, Lüda, which had resulted from the merger of Dalian and Lüshun in December 1950, was made a municipality. In July 1953, Harbin was restored to municipality status, whereas Changchun acquired that status for the first time. Except Beijing and Tianjin, which were under central control, all other municipalities were governed by

6889-485: Was renovated almost in its entirety between 1411 and 1415 during the Ming dynasty (1368–1644). A magistrate of Jining, Shandong sent a memorandum to the throne of the Yongle Emperor protesting the current inefficient means of transporting 4,000,000 dan (428,000,000 liters ) of grain a year by means of transferring it along several different rivers and canals in barge types that went from deep to shallow after
