108-540: Jǐ is the pinyin romanization of the present-day Mandarin pronunciation of the Chinese name written 濟 in traditional characters and 济 in the simplified form used in mainland China . The river's Old Chinese pronunciation has been reconstructed as /*[ts]ˤəjʔ/ or /*ʔsliːlʔ/. Ancient Chinese accounts also wrote the name with the character 泲 , and Lin Chuanjia considered this to be identical with

216-670: A Jesuit missionary in China, wrote the first book that used the Latin alphabet to write Chinese, entitled Xizi Qiji ( 西字奇蹟 ; 'Miracle of Western Letters') and published in Beijing in 1605. Twenty years later, fellow Jesuit Nicolas Trigault published 'Aid to the Eyes and Ears of Western Literati' ( 西儒耳目資 ; Xīrú ěrmù zī )) in Hangzhou. Neither book had any influence among

324-404: A tone number at the end of individual syllables. For example, tóng is written tong . Each tone can be denoted with its numeral the order listed above. The neutral tone can either be denoted with no numeral, with 0, or with 5. Briefly, tone marks should always be placed in the order a, e, i, o, u, ü , with the only exceptions being iu and io where the tone mark is placed on

432-622: A watershed of 795,000 km (307,000 sq mi). Beginning in the Bayan Har Mountains , the river flows generally eastwards before entering the 1,500 km (930 mi) long Ordos Loop, which runs northeast at Gansu through the Ordos Plateau and turns east in Inner Mongolia . The river then turns sharply southwards to form the border between Shanxi and Shaanxi , turns eastwards at its confluence with

540-637: A GB recommendation in 1996, and were last updated in 2012. In practice, however, published materials in China now often space pinyin syllable by syllable. According to Victor H. Mair , this practice became widespread after the Script Reform Committee, previously under direct control of the State Council , had its power greatly weakened in 1985 when it was renamed the State Language Commission and placed under

648-400: A common practice in some sub-dialects, is rarely used in official publications. Even though most initials contain a consonant, finals are not always simple vowels, especially in compound finals ( 复韵母 ; 複韻母 ; fùyùnmǔ ), i.e. when a "medial" is placed in front of the final. For example, the medials [ i ] and [ u ] are pronounced with such tight openings at the beginning of

756-669: A drastic eastward turn at its confluence with the Wei at Tongguan in Shaanxi . However, the official division for the middle reaches of the river run from Hekou in Togtoh County , Inner Mongolia , to Zhengzhou , Henan . The middle reaches are 1,206 km (749 mi) long, with a basin area of 344,000 square kilometers (133,000 sq mi), 45.7% of the total, with a total elevation drop of 890 m (2,920 ft), an average drop of 0.074%. There are 30 large tributaries along

864-719: A failed attempt to protect his realm's capital from the Later Tang . A similar proposal from the Song engineer Li Chun concerning flooding the lower reaches of the river to protect the central plains from the Khitai was overruled in 1020: the Chanyuan Treaty between the two states had expressly forbidden the Song from establishing new moats or changing river courses. Breaches occurred regardless: one at Henglong in 1034 divided

972-498: A final that some native Chinese speakers (especially when singing) pronounce yī ( 衣 ; 'clothes'), officially pronounced /í/ , as /jí/ and wéi ( 围 ; 圍 ; 'to enclose'), officially pronounced /uěi/ , as /wěi/ or /wuěi/ . Often these medials are treated as separate from the finals rather than as part of them; this convention is followed in the chart of finals below. The conventional lexicographical order derived from bopomofo is: In each cell below,

1080-473: A front high rounded vowel, namely after the letters j , q , x , and y . For example, the sound of the word for 'fish' ( 鱼 ; 魚 ) is transcribed in pinyin simply as yú , not as * yǘ . This practice is opposed to Wade–Giles, which always uses ü , and Tongyong Pinyin , which always uses yu . Whereas Wade–Giles needs the umlaut to distinguish between chü (pinyin ju ) and chu (pinyin zhu ), this ambiguity does not arise with pinyin, so

1188-472: A major flood of the regional center Sizhou and Pan's dismissal from court. Subsequently, the river's 1680 flood entirely submerged Sizhou and the nearby Ming Zuling tombs beneath Hongze Lake for centuries until modern irrigation and flood control lowered the water level enough to permit their excavation and the tombs' restoration. Between 1851 and 1855 , the Yellow River returned to the north amid

1296-452: A new channel and inundating most farmland, cities or towns in its path. The traditional Chinese response of building higher and higher levees along the banks sometimes also contributed to the severity of the floods: When flood water did break through the levees, it could no longer drain back into the river bed as it would after a normal flood, as the river bed was sometimes now higher than the surrounding countryside. These changes could cause

1404-478: A north–south extent of about 1,100 km (680 mi). Its total drainage area is about 795,000 square kilometers (307,000 sq mi). According to the China Exploration and Research Society, the source of the Yellow River is at 34°29′31″N 96°20′25″E  /  34.49194°N 96.34028°E  / 34.49194; 96.34028 in the Bayan Har Mountains near the eastern edge of

1512-747: A standard military tactic during the Warring States period . As the Yellow River valley was the major entryway to the Guanzhong area and the state of Qin from the North China Plain , Qin heavily fortified the Hangu Pass ; it saw numerous battles and was also an important chokepoint protecting the Han capitals of Chang'an and Luoyang . Major flooding in AD 11 is credited with the downfall of

1620-773: A transliteration system for Chinese, his discussion ultimately led to a proliferation of proposed schemes. The Wade–Giles system was produced by Thomas Wade in 1859, and further improved by Herbert Giles , presented in Chinese–English Dictionary (1892). It was popular, and was used in English-language publications outside China until 1979. In 1943, the US military tapped Yale University to develop another romanization system for Mandarin Chinese intended for pilots flying over China—much more than previous systems,

1728-662: Is based on the phonological system of Beijing Mandarin. Other romanization schemes have been devised to transcribe those other Chinese varieties, such as Jyutping for Cantonese and Pe̍h-ōe-jī for Hokkien . Based on the "Chinese Romanization" section of ISO 7098:2015, pinyin tone marks should use the symbols from Combining Diacritical Marks , as opposed by the use of Spacing Modifier Letters in bopomofo. Lowercase letters with tone marks are included in GB 2312 and their uppercase counterparts are included in JIS X 0212 ; thus Unicode includes all

1836-493: Is both a medial and a coda, the nucleus may be dropped from writing. In this case, when the coda is a consonant n or ng , the only vowel left is the medial i, u , or ü , and so this takes the diacritic. However, when the coda is a vowel, it is the coda rather than the medial which takes the diacritic in the absence of a written nucleus. This occurs with syllables ending in -ui (from wei : wèi → -uì ) and in -iu (from you : yòu → -iù ). That is, in

1944-401: Is continuously deposited along the bottom of its channel. The sedimentation causes natural dams to slowly accumulate. These subaqueous dams are unpredictable and generally undetectable. Eventually, the enormous amount of water needs to find a new way to the sea, forcing it to take the path of least resistance . When this happens, it bursts out across the flat North China Plain , sometimes taking

2052-473: Is distinct from the concept of consonant and vowel sounds as basic units in traditional (and most other phonetic systems used to describe the Chinese language). Every syllable in Standard Chinese can be described as a pair of one initial and one final, except for the special syllable er or when a trailing -r is considered part of a syllable (a phenomenon known as erhua ). The latter case, though

2160-519: Is not limited only to pinyin, since many languages that use the Latin alphabet natively also assign different values to the same letters. A recent study on Chinese writing and literacy concluded, "By and large, pinyin represents the Chinese sounds better than the Wade–Giles system, and does so with fewer extra marks." As pinyin is a phonetic writing system for modern Standard Chinese , it is not designed to replace characters for writing Literary Chinese ,

2268-614: Is not ordinarily reflected in pinyin spelling. Standard Chinese has many polysyllabic words. Like in other writing systems using the Latin alphabet, spacing in pinyin is officially based on word boundaries. However, there are often ambiguities in partitioning a word. The Basic Rules of the Chinese Phonetic Alphabet Orthography were put into effect in 1988 by the National Educational and National Language commissions. These rules became

2376-568: Is running to the sea with sufficient volume, 1.4 billion tons are carried to the sea per year. One estimate gives 34 kilograms of silt per cubic meter, as opposed to 10 for the Colorado and 1 for the Nile . Its average discharge is said to be 2,110 cubic meters per second (32,000 for the Yangtze), with a maximum of 25,000 and minimum of 245. However, since 1972, it often runs dry before it reaches

2484-460: Is sometimes used instead by convention. For example, it is common for cellphones to use v instead of ü . Additionally, some stores in China use v instead of ü in the transliteration of their names. The drawback is a lack of precomposed characters and limited font support for combining accents on the letter v , ( v̄ v́ v̌ v̀ ). This also presents a problem in transcribing names for use on passports, affecting people with names that consist of

2592-570: Is used to teach Standard Chinese, normally written with Chinese characters , to students already familiar with the Latin alphabet . Pinyin is also used by various input methods on computers and to categorize entries in some Chinese dictionaries . In pinyin, each Chinese syllable is spelled in terms of an optional initial and a final , each of which is represented by one or more letters. Initials are initial consonants, whereas finals are all possible combinations of medials ( semivowels coming before

2700-513: Is written over an i , then it replaces the tittle, as in yī . In dictionaries, neutral tone may be indicated by a dot preceding the syllable—e.g. ·ma . When a neutral tone syllable has an alternative pronunciation in another tone, a combination of tone marks may be used: zhī·dào ( 知道 ) may be pronounced either zhīdào or zhīdao . Before the advent of computers, many typewriter fonts did not contain vowels with macron or caron diacritics. Tones were thus represented by placing

2808-687: The Yuan River that gave Yuanqu County its name. The Ji River changed its precise course several times over the historical period before its disappearance. Generally, it traced its course from an origin near Jiyuan in what is now Henan Province through Shandong to the Bohai Sea . During the Neolithic , the Ji was probably a tributary of the Yellow River , merging with its lower course in

2916-585: The 1332–33 flood or 1344 Yellow River flood during the Yuan dynasty , the 1887 flood during the Qing dynasty which killed anywhere from 900,000 to 2 million people, and a Republic of China era 1931 flood (part of a massive number of floods that year ) that killed 1–4 million people. The cause of the floods is the large amount of fine-grained loess carried by the river from the Loess Plateau , which

3024-479: The 1494 flood . The river flooded many times in the 16th century, including in 1526, 1534, 1558, and 1587. Each flood affected the river's lower course. The 1642 flood was man-made, caused by the attempt of the Ming governor of Kaifeng to use the river to destroy the peasant rebels under Li Zicheng who had been besieging the city for the past six months. He directed his men to break the dikes in an attempt to flood

3132-560: The Bayan Har Mountains , and the Anemaqen ( Amne Machin ) Mountains in Qinghai. The river water is clear and flows steadily. Crystal clear lakes are characteristic of this section. The two main lakes along this section are Lake Gyaring (Zhaling) and Lake Ngoring (Eling), with capacities of 4.7 billion and 10.8 billion m (166 and 381 billion ft ), respectively. At elevations over 4,290 m (14,070 ft) above sea level they are

3240-601: The Chinese Phonetic Alphabet . Hanyu ( 汉语 ; 漢語 ) literally means ' Han language'—that is, the Chinese language—while pinyin literally means 'spelled sounds'. Pinyin is the official romanisation system used in China, Singapore, Taiwan, and by the United Nations . Its use has become common when transliterating Standard Chinese mostly regardless of region, though it is less ubiquitous in Taiwan. It

The river has long been critical to the development of northern China, and is regarded by scholars as a cradle of civilization . Flooding of the river has also caused much destruction, including multiple floods that have resulted in the deaths of over one million people. Among the deadliest were

3564-477: The Ministry of Education . Mair claims that proponents of Chinese characters in the educational bureaucracy "became alarmed that word-based pinyin was becoming a de facto alternative to Chinese characters as a script for writing Mandarin and demanded that all pinyin syllables be written separately." Pinyin superseded older romanization systems such as Wade–Giles and postal romanization , and replaced bopomofo as

3672-639: The North China Plain . At some point, its flooding shifted the lower course of the Yellow River into a separate channel, while the Ji continued to occupy its earlier path. The two rivers ran parallel to one another under the Zhou , Qin , and Han . Under the Han, the Ji River's central course passed through the Great Wild Marsh ( t   大野澤 , s   大野泽 , Dàyězé ) and its mouth

3780-719: The Second Sino-Japanese War , Nationalist troops under Chiang Kai-shek broke the levees holding back the river near the village of Huayuankou in Henan, causing what has been called by Canadian historian, Diana Lary, a "war-induced natural disaster". The goal of the operation was to stop the advancing Japanese troops by following a strategy of "using water as a substitute for soldiers". The 1938 flood of an area covering 54,000 km (20,800 sq mi) took some 500,000 to 900,000 Chinese lives, along with an unknown number of Japanese soldiers. The flood prevented

3888-705: The Shaanxi loess plateau, it is referred to as 'river, my lord' ( 老爺河 , [lo˦˩˨ i˧ xɤu̯˧] ) in the Jin language. In Mongolian , it is called Šar mörön ( Шар мөрөн 'yellow river') or Khatan gol ( Хатан гол 'queen river'). The river is mentioned in the Kul Tigin stele as the 'green river' ( Old Turkic : yašïl ügüz , 𐰖𐱁𐰞𐰽𐰺𐰍). The Tibetan name is "River of the Peacock" ( Tibetan : རྨ ་ ཆུ , Wylie : rma.chu , THL : Ma chu ; 玛曲 ; 瑪曲 ; Mǎ qǔ ). The Yellow River first formed sometime during

3996-457: The Wei River , and flows across the North China Plain before emptying into the Bohai Sea . The river is named for the yellow color of its water, which comes from the large amount of sediment discharged into the water as the river flows through the Loess Plateau . The Yellow River basin was the birthplace of ancient Chinese civilization . According to traditional Chinese historiography ,

4104-553: The Xia dynasty originated on its banks around 2100 BC; Sima Qian 's Shiji ( c.  91 BC ) record that the Xia were founded after the tribes around the Yellow River united to combat the frequent floods in the area. The river has provided fertile soil for agriculture, but since then has flooded and changed course frequently, with one estimate counting 1,593 floods in the 2,540 years between 595 BC and 1946 AD. As such,

Due to its heavy load of silt the Yellow River is a depositing stream – that is, it deposits part of its carried burden of soil in its bed in stretches where it is flowing slowly. These deposits elevate

The source tributaries drain into Gyaring Lake and Ngoring Lake on the western edge of Golog Prefecture high in the Bayan Har Mountains of Qinghai . In the Zoige Basin along the boundary with Gansu , the Yellow River loops northwest and then northeast before turning south, creating the " Ordos Loop ", and then flows generally eastward across the North China Plain to

4428-638: The "father of pinyin". They based their work in part on earlier romanization systems . The system was originally promulgated at the Fifth Session of the 1st National People's Congress in 1958, and has seen several rounds of revisions since. The International Organization for Standardization propagated Hanyu Pinyin as ISO 7098 in 1982, and the United Nations began using it in 1986. Taiwan adopted Hanyu Pinyin as its official romanization system in 2009, replacing Tongyong Pinyin . Matteo Ricci ,

The river went dry during the Wei and Jin period (3rd–4th century   AD). The Ji finally disappeared during one of the massive Yellow River floods of 1852, as the Yellow River shifted its course from below the Shandong Peninsula to north of it. In

Tributaries of the Yellow River listed from its source to its mouth include: The lower reaches of the Yellow River have no tributaries. The Yellow River is notable for the large amount of silt it carries—1.6 billion tons annually at the point where it descends from the Loess Plateau . If it

Since 2003, China has been working on the South–North Water Transfer Project to alleviate the strain on the river's water supply. When the Yellow River was still somewhat clear, it was simply referred to as 'the river' ( 河 , Old Chinese : *gâi ). Observations made at the Yumenkou gorge, where the river leaves

This segment has a total length of 3,472 kilometers (2,157 mi) and total basin area of 386,000 square kilometers (149,000 sq mi), 51.4% of the total basin area. Along this length, the elevation of the Yellow River drops 3,496 meters (11,470 ft), with an average grade of 0.10%. The source section flows mainly through pastures, swamps, and knolls between

5076-634: The Establishment of Diplomatic Relations between the United States and China in 1979. In 2001, the Chinese government issued the National Common Language Law , providing a legal basis for applying pinyin. The current specification of the orthography is GB/T 16159–2012. Chinese phonology is generally described in terms of sound pairs of two initials ( 声母 ; 聲母 ; shēngmǔ ) and finals ( 韵母 ; 韻母 ; yùnmǔ ). This

It was then introduced to primary schools as a way to teach Standard Chinese pronunciation and used to improve the literacy rate among adults. Despite its formal promulgation, pinyin did not become widely used until after the tumult of the Cultural Revolution . In the 1980s, students were trained in pinyin from an early age, learning it in tandem with characters or even before. During

In 1954, the People's Republic of China announced its General Plan to Fundamentally Control Yellow River Flood Disasters and Develop Yellow River Waterworks. It sought to address both flooding risks and to convert rainfall-fed fields of

5400-482: The Jinshan Valley. The abundant hydrodynamic resources stored in this section make it the second most suitable area to build hydroelectric power plants. The famous Hukou Waterfall is in the lower part of this valley on the border of Shanxi and Shaanxi . In the lower reaches, from Zhengzhou to its mouth, a distance of 786 km (488 mi), the river is confined to a levee -lined course as it flows to

From the 1970s to the 1990s, the dry-up trends accelerated, with the Yellow River failing to reach its mouth for an average of approximately 180 days per year in the 1990s. In 1997, the Yellow River did not reach the sea for 226 consecutive days. The Yellow River basin has an east–west extent of about 1,900 kilometers (1,180 mi) and

The silts received from the middle reaches form sediments here, elevating the river bed. Excessive sediment deposits have raised the riverbed several meters above the surrounding ground. That is why this part of the river is called

5940-521: The Yellow River has been considered a blessing and a curse throughout history, and has been nicknamed both "China's Pride" and "China's Sorrow". The Yellow River's basin presently has a population of 120 million people, while over 420 million people live in the immediate provinces which rely on it as a water source. The basin comprises 13 percent of China's cultivated land area. The area receives very uneven rainfall, only 2 percent of China's water runoff —water and sediment flow has decreased five-fold since

6048-421: The Yellow River is 3.91 billion tons in 1933. The highest silt concentration level was recorded in 1977 at 920 kg/m (57.4 lb/ft ). These sediments later deposit in the slower lower reaches of the river, elevating the river bed and creating the famous "river above ground". From Hekou to Yumenkou, the river passes through the longest series of continuous valleys on its main course, collectively called

The Song worked for five years futilely attempting to restore the previous course – using over 35,000 employees, 100,000 conscripts, and 220,000 tons of wood and bamboo in a single year  – before abandoning the project in 1041. The more sluggish river then occasioned a breach at Shanghu that sent

Treatises on traditional flood control techniques were written by officials such as Pan Jixun , who argued that joining branches of the river increased the water's power and this in turn increased its ability to flush sediment. The difficult situation around the confluence of the Yellow River, the Huai, and the Grand Canal, however, still led to

The 1887 flood has been estimated to have killed between 900,000 and 2 million people, and is the second-worst natural disaster in history (excluding famines and epidemics). The Yellow River more or less adopted its present course during the 1897 flood . The 1931 flood killed an estimated 1,000,000 to 4,000,000, and is the worst natural disaster recorded (excluding famines and epidemics). On 9 June 1938, during

In the 2,540 years from 595 BC to 1946 AD, the Yellow River has been reckoned to have flooded 1,593 times, shifting its course 26 times noticeably and nine times severely. These floods include some of the deadliest natural disasters ever recorded. Before modern disaster management, when floods occurred, some of

7560-411: The main outlet north towards Tianjin in 1048. In 1128, Song troops under the Kaifeng governor Du Chong ( 杜 充 , Dù Chōng , d.   1141) breached the southern dikes of the Yellow River in an effort to stop the advancing Jin army. The resulting major river avulsion allowed the Yellow to capture the Si and other tributaries of the Huai River . For the first time in recorded history,

7668-690: The method of Chinese phonetic instruction in mainland China . The ISO adopted pinyin as the standard romanization for modern Chinese in 1982 (ISO 7098:1982, superseded by ISO 7098:2015). The United Nations followed suit in 1986. It has also been accepted by the government of Singapore , the United States's Library of Congress , the American Library Association , and many other international institutions. Pinyin assigns some Latin letters sound values which are quite different from those of most languages. This has drawn some criticism as it may lead to confusion when uninformed speakers apply either native or English assumed pronunciations to words. However, this problem

7776-433: The middle reaches, and the water flow is increased by 43.5% on this stage. The middle reaches contribute 92% of the river's silts. The middle stream of the Yellow River passes through the Loess Plateau , where substantial erosion takes place. The large amount of mud and sand discharged into the river makes the Yellow River the most sediment -laden river in the world. The highest recorded annual level of silts discharged into

7884-426: The modern Loess Plateau , indicated the river changed to muddy sometime between 367 BC and 165 AD, according to chronicles' records. The alternative names 'murky river' ( 濁河 , *drôk-gâi ) and '(muddy) yellow river' ( 黃河 , *gwâŋ-gâi ) were attested in 145 BC and in 429 AD respectively. The name Yellow River fully replaces Murky River by the end of Tang dynasty , for unclear reasons. In

7992-404: The more convenient form ju is used instead of jü . Genuine ambiguities only happen with nu / nü and lu / lü , which are then distinguished by an umlaut. Many fonts or output methods do not support an umlaut for ü or cannot place tone marks on top of ü . Likewise, using ü in input methods is difficult because it is not present as a simple key on many keyboard layouts. For these reasons v

8100-495: The most common way to transcribe them in English. Pinyin has also become the dominant Chinese input method in mainland China, in contrast to Taiwan, where bopomofo is most commonly used. Families outside of Taiwan who speak Mandarin as a mother tongue use pinyin to help children associate characters with spoken words which they already know. Chinese families outside of Taiwan who speak some other language as their mother tongue use

8208-579: The names of several pinyin letters using -ê finals. According to the Scheme for the Chinese Phonetic Alphabet , ng can be abbreviated with the shorthand ŋ . However, this shorthand is rarely used due to difficulty of entering it on computers. (Starts with the vowel sound in f a ther and ends in the velar nasal ; like s ong in some dialects of American English) An umlaut is added to ⟨ u ⟩ when it occurs after

8316-530: The northeast across the North China Plain before emptying into the Bohai Sea . The basin area in this stage is only 23,000 square kilometers (8,900 sq mi), a mere 3% of the total, because few tributaries add to the flow in this stage; nearly all rivers to the south drain into the Huai River , whereas those to the north drain into the Hai River . The Huai River Basin, for example, is separated from

8424-590: The northern states of Qi and Jin . From the Si, the Ji River then had access to the Huai River , which connected to the new course of the Yellow River through the Hongguo Canal and with the Yangtze River through the Hangou Canal just completed by Fuchai's men in 486   BC. Under the Zhou , the state of Qi was centered on the broad floodplain of the Ji. It also used the "clear Ji" along with

8532-558: The pinyin letters assigned to each initial are accompanied by their phonetic realizations in brackets, notated according to the International Phonetic Alphabet . In each cell below, the first line indicates the International Phonetic Alphabet (IPA) transcription, the second indicates pinyin for a standalone (no-initial) form, and the third indicates pinyin for a combination with an initial. Other than finals modified by an -r , which are omitted,

8640-473: The pinyin system, four main tones of Mandarin are shown by diacritics: ā, á, ǎ, and à. There is no symbol or diacritic for the neutral tone: a. The diacritic is placed over the letter that represents the syllable nucleus , unless that letter is missing. Tones are used in Hanyu Pinyin symbols, and they do not appear in Chinese characters. Tones are written on the finals of Chinese pinyin. If the tone mark

8748-575: The population might initially die from drowning and many more would suffer later from the ensuing famine and spread of diseases. In Chinese mythology , the giant Kua Fu drained the Yellow River and the Wei River to quench his burning thirst as he pursued the Sun. Historical documents from the Spring and Autumn period and Qin dynasty indicate that the Yellow River at that time flowed considerably north of its present course. These accounts show that after

8856-411: The practice to use "LYU" and "NYU" in passports. Although nüe written as nue , and lüe written as lue are not ambiguous, nue or lue are not correct according to the rules; nüe and lüe should be used instead. However, some Chinese input methods support both nve / lve (typing v for ü ) and nue / lue . The pinyin system also uses four diacritics to mark the tones of Mandarin . In

8964-540: The present course of the Yellow River include (from west to east) Lanzhou , Yinchuan , Wuhai , Baotou , Luoyang , Zhengzhou , Kaifeng , and Jinan . The current mouth of the Yellow River is located at Kenli County , Shandong. The river is commonly divided into three stages. These are roughly the northeast of the mountainous Tibetan Plateau , the Ordos Loop and Loess Plateau , and the North China Plain . However, different scholars have different opinions on how

9072-456: The process, it overtook the Ji and assumed its bed. Other parts of the former course of the Ji form the present Xiaoqing River . The Ji River was the namesake of Jiyuan ("Source of the Ji") and Jinan ("Lands South of the Ji"). Pinyin Hanyu Pinyin , or simply pinyin , is the most common romanization system for Standard Chinese . In official documents, it is referred to as

9180-441: The rainy season from July to October, when 60% of the annual volume of the river flows. Maximum demand for irrigation is needed between March and June. In order to capture excess water for use when needed and for flood control and electricity generation, several dams have been built, but their expected life is limited due to the high silt load. A proposed South–North Water Transfer Project involves several schemes to divert water from

9288-502: The rebels, but destroyed his own city instead: the flood and the ensuing famine and plague are estimated to have killed 300,000 of the city's previous population of 378,000. The once-prosperous city was nearly abandoned until its rebuilding under the Kangxi Emperor in the Qing dynasty . The question of how aggressively flooding should be controlled, and whether it should be steered back to its original channels when it migrated,

9396-477: The regions along the river are mostly deserts and grasslands, with very few tributaries. The flow is slow. The Hetao Plain has a length of 900 km (560 mi) and width of 30 to 50 km (19 to 31 mi). It is historically the most important irrigation plain along the Yellow River. The Ordos Loop formed by an enormous twist of the Yellow River, beginning at Zhongning County in Ningxia and ending with

9504-487: The result appears very similar to modern Hanyu Pinyin. Hanyu Pinyin was designed by a group of mostly Chinese linguists, including Wang Li , Lu Zhiwei , Li Jinxi , Luo Changpei , as well as Zhou Youguang (1906–2017), an economist by trade, as part of a Chinese government project in the 1950s. Zhou, often called "the father of pinyin", worked as a banker in New York when he decided to return to China to help rebuild

9612-455: The river passed Luoyang , it flowed along the border between Shanxi and Henan Provinces, then continued along the border between Hebei and Shandong before emptying into Bohai Bay near present-day Tianjin . Another outlet followed essentially the present course. The river left these paths in 602 BC and shifted several hundred kilometers to the east. Sabotage of dikes, canals, and reservoirs and deliberate flooding of rival states became

9720-693: The river skirts through the high-altitude peat bog known as the Zoigê Wetlands and makes a sharp turn towards the northwest forming the border between Maqu and Zoigê County in Sichuan . Flowing now along the northern edge of Amne Machin, the river reenters Qinghai and gradually curves north towards the Longyang Gorge at Xinghai . The valley section stretches from Longyang Gorge in Qinghai to Qingtong Gorge in Gansu. Steep cliffs line both sides of

9828-517: The river's mouth to shift as much as 480 km (300 mi), sometimes reaching the ocean to the north of the Shandong Peninsula and sometimes to the south. Another historical source of devastating floods is the collapse of upstream ice dams in Inner Mongolia with an accompanying sudden release of vast quantities of impounded water. There have been 11 such major floods in the past century, each causing tremendous loss of life and property. Nowadays, explosives dropped from aircraft are used to break

9936-501: The river. The water bed is narrow and the average drop is large, so the flow in this section is extremely turbulent and fast. There are 20 gorges in this section, the most famous of these being the Longyang , Jishi, Liujia , Bapan, and Qingtong gorges. The flow conditions in this section makes it the best location for hydroelectric plants. The Yellow River exits Qinghai for the second and final time in these gorges and enters Gansu for

10044-423: The riverbed which flows between natural levees in its lower reaches. Should a flood occur, the river may break out of the levees into the surrounding lower flood plain and take a new channel. Historically this has occurred about once every hundred years. In modern times, considerable effort has been made to strengthen levees and control floods. Below is an incomplete list of hydroelectric power stations built on

10152-491: The sea. The low volume is due to increased agricultural irrigation, increased by a factor of five since 1950. Water diverted from the river as of 1999 served 140 million people and irrigated 74,000 km (29,000 sq mi) of land. The Yellow River delta totals 8,000 square kilometers (3,100 square miles). However, with the decrease in silt reaching the sea, it has been reported to be shrinking slightly each year since 1996 through erosion. The highest volume occurs during

10260-592: The second time just before Liujia Gorge. Downstream from the Yanguo Gorge, the provincial capital of Lanzhou is built upon the Yellow River's banks. The Yellow River flows northeasterly out of Gansu and into Ningxia before the Qingtong Gorge. After emerging from the Qingtong Gorge, the river comes into a section of vast alluvial plains , the Yinchuan Plain and Hetao Plain . In this section,

10368-418: The second vowel instead. Pinyin tone marks appear primarily above the syllable nucleus—e.g. as in kuài , where k is the initial, u the medial, a the nucleus, and i is the coda. There is an exception for syllabic nasals like /m/ , where the nucleus of the syllable is a consonant: there, the diacritic will be carried by a written dummy vowel. When the nucleus is / ə / (written e or o ), and there

10476-434: The short-lived Xin dynasty , and another flood in AD 70 returned the river north of Shandong on essentially its present course. From around the beginning of the 3rd century, the importance of the Hangu Pass was reduced, with the major fortifications and military bases moved upriver to Tongguan . In AD 923, the desperate Later Liang general Duan Ning again broke the dikes, flooding 1,000 square miles (2,600 km ) in

10584-443: The sound lü or nü , particularly people with the surname 吕 ( Lǚ ), a fairly common surname, particularly compared to the surnames 陆 ( Lù ), 鲁 ( Lǔ ), 卢 ( Lú ) and 路 ( Lù ). Previously, the practice varied among different passport issuing offices, with some transcribing as "LV" and "NV" while others used "LU" and "NU". On 10 July 2012, the Ministry of Public Security standardized

10692-498: The standard written language prior to the early 1900s. In particular, Chinese characters retain semantic cues that help distinguish differently pronounced words in the ancient classical language that are now homophones in Mandarin. Thus, Chinese characters remain indispensable for recording and transmitting the corpus of Chinese writing from the past. Pinyin is not designed to transcribe varieties other than Standard Chinese, which

10800-496: The system to teach children Mandarin pronunciation when learning vocabulary in elementary school. Since 1958, pinyin has been actively used in adult education as well, making it easier for formerly illiterate people to continue with self-study after a short period of pinyin literacy instruction. Yellow River The Yellow River is the second-longest river in China and the sixth-longest river system on Earth, with an estimated length of 5,464 km (3,395 mi) and

10908-693: The three stages are divided. This article mainly adopts the division used by the Yellow River Conservancy Commission . The Yellow River derived sediments have been transported out of the Bohai Sea, all way to the North Yellow Sea and South Yellow Sea, and formed a Distal Depocenter around the Shandong Peninsula. The upper reaches of the Yellow River constitute a segment starting from its source in

11016-649: The two largest plateau freshwater lakes nationwide. A significant amount of land in the Yellow River's source area has been designated as the Sanjiangyuan ("'Three Rivers' Sources") National Nature Reserve , to protect the source region of the Yellow River, the Yangtze , and the Mekong . Flowing east at the eastern edge of the Amne Machin Mountains, the Yellow River enters Maqu County in Gansu . Here,

11124-441: The use of a non-pinyin romanization system, such as one that uses final consonants to indicate tones. Technically, i, u, ü without a following vowel are finals, not medials, and therefore take the tone marks, but they are more concisely displayed as above. In addition, ê [ɛ] ( 欸 ; 誒 ) and syllabic nasals m ( 呒 , 呣 ), n ( 嗯 , 唔 ), ng ( 嗯 , 𠮾 ) are used as interjections or in neologisms ; for example, pinyin defines

11232-435: The vowel), a nucleus vowel, and coda (final vowel or consonant). Diacritics are used to indicate the four tones found in Standard Chinese, though these are often omitted in various contexts, such as when spelling Chinese names in non-Chinese texts. Hanyu Pinyin was developed in the 1950s by a group of Chinese linguists including Wang Li , Lu Zhiwei , Li Jinxi , Luo Changpei and Zhou Youguang , who has been called

11340-559: Was a topic of controversy in the imperial court. Rival cliques made arguments based on budgetary, technical and strategic criteria. Geographer Charles Greer identifies two competing schools of thought on how to control the Yellow River. One, which he identifies as Confucian , advocated containing the river between higher levees, thus maximizing the amount of river basin land that could be cultivated. The other, which he associates with Taoism , favored lower levees separated by as much as 5-10 kilometers. In one particular long-running debate during

11448-528: Was authored in January 1956 by Ye Laishi , Lu Zhiwei and Zhou Youguang. A revised Pinyin scheme was proposed by Wang Li, Lu Zhiwei and Li Jinxi, and became the main focus of discussion among the group of Chinese linguists in June 1956, forming the basis of Pinyin standard later after incorporating a wide range of feedback and further revisions. The first edition of Hanyu Pinyin was approved and officially adopted at

11556-692: Was in Qiansheng Commandery ( 千乘 郡 , Qiānchéng Jùn ). The area around the Ji River was among the most densely populated in China during the Neolithic Age , when its plains were a center for the Longshan and Yueshi cultures . It was honored as a god in ancient Chinese religion . Sima Qian lists the Ji among the rivers connected by the Honggou Canal ( t   鴻溝 , s   鸿沟 , Hónggōu , "Canal of

11664-576: Was not a linguist by trade. Hanyu Pinyin incorporated different aspects from existing systems, including Gwoyeu Romatzyh (1928), Latinxua Sin Wenz (1931), and the diacritics from bopomofo (1918). "I'm not the father of pinyin", Zhou said years later; "I'm the son of pinyin. It's [the result of] a long tradition from the later years of the Qing dynasty down to today. But we restudied the problem and revisited it and made it more perfect." An initial draft
