County (People's Republic Of China)
Counties ( zh, t=縣, s=县, hp=Xiàn), formally county-level divisions, are found in the third level of the administrative hierarchy in Provinces and Autonomous regions and the second level in municipalities and Hainan, a level that is known as "county level" and also contains autonomous counties, county-level cities, banners, autonomous banners and City districts. There are 1,355 counties in Mainland China out of a total of 2,851 county-level divisions. The term ''xian'' is sometimes translated as "district" or "prefecture" when put in the context of Chinese history. History ''Xian'' have existed since the Warring States period and were set up nationwide by the Qin Dynasty. The number of counties in China proper gradually increased from dynasty to dynasty. As Qin Shi Huang reorganized the counties after his unification, there were about 1,000. Under the Eastern Han Dynasty, the number of counties increased to above 1,000. About 1400 existed when the Sui dyn ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Karst Topography
Karst is a topography formed from the dissolution of soluble rocks such as limestone, dolomite, and gypsum. It is characterized by underground drainage systems with sinkholes and caves. It has also been documented for more weathering-resistant rocks, such as quartzite, given the right conditions. Subterranean drainage may limit surface water, with few to no rivers or lakes. However, in regions where the dissolved bedrock is covered (perhaps by debris) or confined by one or more superimposed non-soluble rock strata, distinctive karst features may occur only at subsurface levels and can be totally missing above ground. The study of ''paleokarst'' (buried karst in the stratigraphic column) is important in petroleum geology because as much as 50% of the world's hydrocarbon reserves are hosted in carbonate rock, and much of this is found in porous karst systems. Etymology The English word ''karst'' was borrowed from German in the late 19th century, which entered German much ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tremella Fuciformis
''Tremella fuciformis'' is a species of fungus; it produces white, frond-like, gelatinous basidiocarps (fruiting bodies). It is widespread, especially in the tropics, where it can be found on the dead branches of broadleaf trees. This fungus is commercially cultivated and is one of the most popular fungi in the cuisine and medicine of China. ''Tremella fuciformis'' is commonly known as snow fungus, snow ear, silver ear fungus, white jelly mushroom, and white cloud ears. ''Tremella fuciformis'' is a parasitic yeast, and grows as a slimy, mucus-like film until it encounters its preferred hosts, various species of ''Annulohypoxylon'' (or possibly '' Hypoxylon'') fungi, whereupon it then invades, triggering the aggressive mycelial growth required to form the fruiting bodies. Taxonomy and naming ''Tremella fuciformis'' was first described in 1856 by English mycologist Miles Joseph Berkeley, based on collections made in Brazil by the botanist and explorer Richard Spruce. In 1939, J ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
People's Liberation Army
The People's Liberation Army (PLA) is the principal military force of the People's Republic of China and the armed wing of the Chinese Communist Party (CCP). The PLA consists of five service branches: the Ground Force, Navy, Air Force, Rocket Force, and Strategic Support Force. It is under the leadership of the Central Military Commission (CMC) with its chairman as commander-in-chief. The PLA can trace its origins during the Republican Era to the left-wing units of the National Revolutionary Army (NRA) of the Kuomintang (KMT) when they broke away on 1 August 1927 in an uprising against the nationalist government as the Chinese Red Army before being reintegrated into the NRA as units of New Fourth Army and Eighth Route Army during the Second Sino-Japanese War. The two NRA communist units were reconstituted into the PLA on 10 October 1947. Today, the majority of military units around the country are assigned to one of five theater commands by geographical locat ...

Long March
The Long March (, lit. ''Long Expedition'') was a military retreat undertaken by the Red Army of the Chinese Communist Party (CCP), the forerunner of the People's Liberation Army, to evade the pursuit of the National Army of the Chinese Nationalist Party (CNP/KMT). Strictly speaking, the Long March was a series of marches, as various Communist armies in the south escaped to the north and west. However, the most famous began in the Jiangxi (Jiangxi) province in October 1934 and ended in the Shaanxi province in October 1935. The First Front Army of the Chinese Soviet Republic, led by an inexperienced military commission, was on the brink of annihilation by Generalissimo Chiang Kai-shek's troops in their stronghold in Jiangxi province. The CCP, under the eventual command of Mao Zedong and Zhou Enlai, escaped in a circling retreat to the west and north, which reportedly traversed over over 370 days.Zhang, Chunhou. Vaughan, C.

Gypsum
Gypsum is a soft sulfate mineral composed of calcium sulfate dihydrate, with the chemical formula . It is widely mined and is used as a fertilizer and as the main constituent in many forms of plaster, blackboard or sidewalk chalk, and drywall. Alabaster, a fine-grained white or lightly tinted variety of gypsum, has been used for sculpture by many cultures including Ancient Egypt, Mesopotamia, Ancient Rome, the Byzantine Empire, and the Nottingham alabasters of Medieval England. Gypsum also crystallizes as translucent crystals of selenite. It forms as an evaporite mineral and as a hydration product of anhydrite. The Mohs scale of mineral hardness defines gypsum as hardness value 2 based on scratch hardness comparison. Etymology and history The word '' gypsum'' is derived from the Greek word (), "plaster". Because the quarries of the Montmartre district of Paris have long furnished burnt gypsum ( calcined gypsum) used for various purposes, this dehydrated gyp ...

Dolomite (mineral)
Dolomite () is an anhydrous carbonate mineral composed of calcium magnesium carbonate, ideally The term is also used for a sedimentary carbonate rock composed mostly of the mineral dolomite. An alternative name sometimes used for the dolomitic rock type is dolostone. History As stated by Nicolas-Théodore de Saussure the mineral dolomite was probably first described by Carl Linnaeus in 1768. In 1791, it was described as a rock by the French naturalist and geologist Déodat Gratet de Dolomieu (1750–1801), first in buildings of the old city of Rome, and later as samples collected in the mountains now known as the Dolomite Alps of northern Italy. Nicolas-Théodore de Saussure first named the mineral (after Dolomieu) in March 1792. Properties The mineral dolomite crystallizes in the trigonal-rhombohedral system. It forms white, tan, gray, or pink crystals. Dolomite is a double carbonate, having an alternating structural arrangement of calcium and magnesium ions. ...

Prefecture-level City
A prefecture-level city () or prefectural city is an administrative division of the People's Republic of China (PRC), ranking below a province and above a county in China's administrative structure. During the Republican era, many of China's prefectural cities were designated as counties as the country's second level division below a province. From 1949 to 1983, the official term was a province-administrated city (Chinese: 省辖市). Prefectural level cities form the second level of the administrative structure (alongside prefectures, leagues and autonomous prefectures). Administrative chiefs (mayors) of prefectural level cities generally have the same rank as a division chief () of a national ministry. Since the 1980s, most former prefectures have been renamed into prefectural level cities. A prefectural level city is a "city" () and "prefecture" () that have been merged into one consolidated and unified jurisdiction. As such it is simultaneously a city, which is a muni ...
