Hulan River
The Hulan River (Chinese: 呼兰河; Pinyin: Hūlán Hé; English: ''Call Orchid'') is a river in Heilongjiang Province, China. The Hulan rises in the Lesser Khingan mountains, south of Yichun (). It flows west past Tieli and north of Suihua. After the confluence with the Tongken River, it turns south to join the Songhua River in Hulan County, where it flows into the new Dadingshan Reservoir, just east of Harbin (), . The river meanders extensively across the Northeast China Plain, creating many bifurcations and oxbow lakes. The approximate length is 350 km, but there is often more than one stream, and the actual distance including all the bends is 532 km. The area of the catchment basin is 31,207 km2. It has a wide floodplain of fertile black soil. After a comprehensive management plan for the river basin was implemented in the 1950s, it became a center of production for grain, flax and sugar beet. There is a tributary called the Xiaohulan River (''Little Hulan''), which f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chinese Language
Chinese (, especially when referring to written Chinese) is a group of languages spoken natively by the ethnic Han Chinese majority and many minority ethnic groups in Greater China. About 1.3 billion people (or approximately 16% of the world's population) speak a variety of Chinese as their first language. Chinese languages form the Sinitic branch of the Sino-Tibetan languages family. The spoken varieties of Chinese are usually considered by native speakers to be variants of a single language. However, their lack of mutual intelligibility means they are sometimes considered separate languages in a family. Investigation of the historical relationships among the varieties of Chinese is ongoing. Currently, most classifications posit 7 to 13 main regional groups based on phonetic developments from Middle Chinese, of which the most spoken by far is Mandarin (with about 800 million speakers, or 66%), followed by Min (75 million, e.g. Southern Min), Wu (74 million, e.g. Shangh ...

Harbin
Harbin (; mnc, , v=Halbin; ) is a sub-provincial city and the provincial capital and the largest city of Heilongjiang province, People's Republic of China, as well as the second largest city by urban population after Shenyang and largest city by metropolitan population (urban and rural together) in Northeast China. Harbin has direct jurisdiction over nine metropolitan districts, two county-level cities and seven counties, and is the eighth most populous Chinese city according to the 2020 census. The built-up area of Harbin (which consists of all districts except Shuangcheng and Acheng) had 5,841,929 inhabitants, while the total metropolitan population was up to 10,009,854, making it one of the 50 largest urban areas in the world. Harbin, whose name was originally a Manchu word meaning "a place for drying fishing nets", grew from a small rural settlement on the Songhua River to become one of the largest cities in Northeast China. Founded in 1898 with the coming of the C ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Xiao Hong
Xiao Hong or Hsiao Hung (1 June 1911 – 22 January 1942) was a Chinese writer. Her ruming (乳名，infant name) was Zhang Ronghua (張榮華). Her xueming (學名，formal name used at school) was Zhang Xiuhuan (張秀環). Her name Zhang Naiying () was changed by her grandfather; she also used the pen names Qiao Yin and Lingling. Xiao Hong's childhood Xiao Hong was born into a wealthy landlord family on 1 June 1911 the day of the Dragon Boat Festival in Hulan County, in what is now Heilongjiang Province. Xiao Hong's childhood was not a happy one. Her mother died when she was nine years old and she attended a girls school in Harbin in 1927, where she encountered the progressive ideas of the May Fourth movement as well as Chinese and foreign literature. Her childhood was deeply influenced by two people: her father, he was apparently a difficult man who was cold and ruthless, and her grandfather, who was the only one in the family who understood her. In her "Yong yuan de chong j ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Molybdenum
Molybdenum is a chemical element with the symbol Mo and atomic number 42 which is located in period 5 and group 6. The name is from Neo-Latin ''molybdaenum'', which is based on Ancient Greek ', meaning lead, since its ores were confused with lead ores. Molybdenum minerals have been known throughout history, but the element was discovered (in the sense of differentiating it as a new entity from the mineral salts of other metals) in 1778 by Carl Wilhelm Scheele. The metal was first isolated in 1781 by Peter Jacob Hjelm. Molybdenum does not occur naturally as a free metal on Earth; it is found only in various oxidation states in minerals. The free element, a silvery metal with a grey cast, has the sixth-highest melting point of any element. It readily forms hard, stable carbides in alloys, and for this reason most of the world production of the element (about 80%) is used in steel alloys, including high-strength alloys and superalloys. Most molybdenum compounds have low solubili ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tributary
A tributary, or affluent, is a stream or river that flows into a larger stream or main stem (or parent) river or a lake. A tributary does not flow directly into a sea or ocean. Tributaries and the main stem river drain the surrounding drainage basin of its surface water and groundwater, leading the water out into an ocean. The Irtysh is a chief tributary of the Ob river and is also the longest tributary river in the world with a length of . The Madeira River is the largest tributary river by volume in the world with an average discharge of . A confluence, where two or more bodies of water meet, usually refers to the joining of tributaries. The opposite to a tributary is a distributary, a river or stream that branches off from and flows away from the main stream. PhysicalGeography.net, Michael Pidwirny & S ...

Oxbow Lakes
An oxbow lake is a U-shaped lake or pool that forms when a wide meander of a river is cut off, creating a free-standing body of water. In South Texas, oxbows left by the Rio Grande are called '' resacas''. In Australia, oxbow lakes are called billabongs. The word "oxbow" can also refer to a U-shaped bend in a river or stream, whether or not it is cut off from the main stream. Geology An oxbow lake forms when a meandering river erodes through the neck of one of its meanders. This takes place because meanders tend to grow and become more curved over time. The river then follows a shorter course that bypasses the meander. The entrances to the abandoned meander eventually silt up, forming an oxbow lake. Because oxbow lakes are stillwater lakes, with no current flowing through them, the entire lake gradually silts up, becoming a bog or swamp and then evaporating completely. When a river reaches a low-lying plain, often in its final course to the sea or a lake, it meanders wid ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
River Bifurcation
River bifurcation (from la, furca, fork) occurs when a river flowing in a single stream separates into two or more separate streams (called distributaries) which then continue downstream. Some rivers form complex networks of distributaries, typically in their deltas. If the streams eventually merge again or empty into the same body of water, then the bifurcation forms a river island. River bifurcation may be temporary or semi-permanent, depending on the strength of the material that is dividing the two distributaries. For example, a mid-stream island of soil or silt in a delta is most likely temporary, due to low material strength. A location where a river divides around a rock fin, e.g. a volcanically formed dike, or a mountain, may be more lasting as a result of higher material strength and resistance to weathering and erosion. A bifurcation may also be man-made, for example when two streams are separated by a long bridge pier. Scientific study of bifurcation River bifurcati ...

Northeast China Plain
The Northeast China Plain (), commonly known as Song liao Plain or the Manchurian Plain or just the Northeast Plain, is located in Northeast China, historically also known as Manchuria. It lies between the Greater and Lesser Khingan and Changbai mountains, ending at the coast at Liaodong Bay in the Bohai Sea. Covering 350,000 km2, it is China's largest plain, with an elevation of lower than 200 meters, and less than 100 meters to the southwest. The Songhua, Nen, and Liao rivers run through it. The Manchurian Plain of Asia is the other name of the Amur valley.Encyclopedia Britannica''Northeast Plain'' Retrieved 12-5-2019. The Northeast Plain includes Songnen Plain in the north, Liaohe Plain in the south, and Sanjiang Plain in the northeast. The Songnen plain was formed by the Songhua and alluvial soils from the Nen. The Liaohe plain, located in the hilly areas near Changchun, was created by the separation of watersheds of the Songhua and Liaohe, which are collectively know ...

Meanders
A meander is one of a series of regular sinuous curves in the channel of a river or other watercourse. It is produced as a watercourse erodes the sediments of an outer, concave bank (cut bank) and deposits sediments on an inner, convex bank which is typically a point bar. The result of this coupled erosion and sedimentation is the formation of a sinuous course as the channel migrates back and forth across the axis of a floodplain. The zone within which a meandering stream periodically shifts its channel is known as a meander belt. It typically ranges from 15 to 18 times the width of the channel. Over time, meanders migrate downstream, sometimes in such a short time as to create civil engineering challenges for local municipalities attempting to maintain stable roads and bridges.Neuendorf, K.K.E., J.P.

Hulan County
Hulan District () is one of nine districts of the prefecture-level city of Harbin, the capital of Heilongjiang Province, Northeast China. It covers part of the northeastern suburbs. The district was approved to establish from the former ''Hulan County'' () by the Chinese State Council on February 4, 2004. It borders Bayan County to the east, Bin County to the southeast, Daowai District to the south, and Songbei District to the southwest, as well as the prefecture-level city of Suihua to the northwest. History After World War II, the Hulan District was home of Manchukuo veterans who became homeless because they failed to conscript the newly People's Liberation Army. Administrative divisions Hulan District is divided into 17 subdistricts, 7 towns and 3 townships. ;17 subdistricts * Hulan (), Lanhe (), Yaobo (), Limin (), Kangjin (), Shuangjing (), Jianshelu (), Xueyuanlu (), Zhangling (), Shenjia (), Nanjinglu (), Yumin (), Yutian (), Yuqiang (), Xiaoxiang (), Go ...

Pinyin
Hanyu Pinyin (), often shortened to just pinyin, is the official romanization system for Standard Mandarin Chinese in China, and to some extent, in Singapore and Malaysia. It is often used to teach Mandarin, normally written in Chinese form, to learners already familiar with the Latin alphabet. The system includes four diacritics denoting tones, but pinyin without tone marks is used to spell Chinese names and words in languages written in the Latin script, and is also used in certain computer input methods to enter Chinese characters. The word ' () literally means "Han language" (i.e. Chinese language), while ' () means "spelled sounds". The pinyin system was developed in the 1950s by a group of Chinese linguists including Zhou Youguang and was based on earlier forms of romanizations of Chinese. It was published by the Chinese Government in 1958 and revised several times. The International Organization for Standardization (ISO) adopted pinyin as an international standard ...

Songhua River
The Songhua Postal Romanization, or Sunghwa River (also Haixi or Xingal, russian: Сунгари ''Sungari'') is one of the primary List of rivers of China, rivers of China, and the longest tributary of the Amur. It flows about from the Changbai Mountains on the China–North Korea border through China's northeastern Jilin and Heilongjiang provinces. The river drains of land, and has an annual discharge of to . The extreme flatness of the Northeast China Plain has caused the river to meander over time, filling the wide plain with oxbow lakes, as remnants of the previous paths of the river. Geography The Songhua rises south of Heaven Lake, near the China-North Korea border. From there it flows north, to be interrupted by the Baishan Dam, Baishan, Hongshi Dam, Hongshi and Fengman Dam, Fengman hydroelectricity, hydroelectric dams. The Fengman Dam forms a lake that stretches for . Below the dam, the Second Songhua flows north through Jilin, then northwest until it is joined b ...
