Postal Code Of China
Postal codes in the People's Republic of China () are postal codes used by China Post for the delivery of letters and goods within mainland China. China Post uses a six-digit all-numerical system with four tiers: the first tier, composed of the first two digits, show the province, province-equivalent municipality, or autonomous region; the second tier, composed of the third digit, shows the postal zone within the province, municipality or autonomous region; the fourth digit serves as the third tier, which shows the postal office within prefectures or prefecture-level cities; the last two digits are the fourth tier, which indicates the specific mailing area for delivery. The range 000000–009999 was originally marked for Taiwan (The Republic of China) but is not used because it not under the control of the People's Republic of China. Mail to ROC is treated as international mail, and uses postal codes set forth by Chunghwa Post. Codes starting from 999 are the internal codes use ...

Postal Romanization
Postal romanization was a system of transliterating Chinese place names developed by postal authorities in the late 19th and early 20th centuries. For many cities, the corresponding postal romanization was the most common English-language form of the city's name from the 1890s until the 1980s, when postal romanization was replaced by pinyin, but the system remained in place on Taiwan until 2002. In 1892, Herbert Giles created a romanization system called Nanking syllabary. The Imperial Maritime Customs Post Office would cancel postage with a stamp that gave the city of origin in Latin letters, often romanized using Giles's system. In 1896, the Customs Post was combined with other postal services and renamed the Chinese Imperial Post. As a national agency, the Imperial Post was an authority on Chinese place names. When the Wade–Giles system of romanization became widespread, some argued that the post office should adopt it. This idea was rejected at a conference held in 1906 ...

Oil Shale
Oil shale is an organic-rich fine-grained sedimentary rock containing kerogen (a solid mixture of organic chemical compounds) from which liquid hydrocarbons can be produced. In addition to kerogen, general composition of oil shales constitutes inorganic substance and bitumens. Based on their deposition environment, oil shales are classified as marine, lacustrine and terrestrial oil shales. Oil shales differ from oil-''bearing'' shales, shale deposits that contain petroleum (tight oil) that is sometimes produced from drilled wells. Examples of oil-''bearing'' shales are the Bakken Formation, Pierre Shale, Niobrara Formation, and Eagle Ford Formation. Accordingly, shale oil produced from oil shale should not be confused with tight oil, which is also frequently called shale oil. Deposits of oil shale occur around the world, including major deposits in the United States. A 2016 estimate of global deposits set the total world resources of oil shale equivalent of of oil in place. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dolomite (rock)
Dolomite (also known as dolomite rock, dolostone or dolomitic rock) is a sedimentary carbonate rock that contains a high percentage of the mineral dolomite, CaMg(CO3)2. It occurs widely, often in association with limestone and evaporites, though it is less abundant than limestone and rare in Cenozoic rock beds (beds less than about 66 million years in age). The first geologist to distinguish dolomite rock from limestone was Belsazar Hacquet in 1778. Most dolomite was formed as a magnesium replacement of limestone or of lime mud before lithification. The geological process of conversion of calcite to dolomite is known as dolomitization and any intermediate product is known as dolomitic limestone. The "dolomite problem" refers to the vast worldwide depositions of dolomite in the past geologic record in contrast to the limited amounts of dolomite formed in modern times. Recent research has revealed sulfate-reducing bacteria living in anoxic conditions precipitate dolomite which ind ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Natural Gas
Natural gas (also called fossil gas or simply gas) is a naturally occurring mixture of gaseous hydrocarbons consisting primarily of methane in addition to various smaller amounts of other higher alkanes. Low levels of trace gases like carbon dioxide, nitrogen, hydrogen sulfide, and helium are also usually present. Natural gas is colorless and odorless, so odorizers such as mercaptan (which smells like sulfur or rotten eggs) are commonly added to natural gas supplies for safety so that leaks can be readily detected. Natural gas is a fossil fuel and non-renewable resource that is formed when layers of organic matter (primarily marine microorganisms) decompose under anaerobic conditions and are subjected to intense heat and pressure underground over millions of years. The energy that the decayed organisms originally obtained from the sun via photosynthesis is stored as chemical energy within the molecules of methane and other hydrocarbons. Natural gas can be burned fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coal
Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams. Coal is mostly carbon with variable amounts of other elements, chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years. Vast deposits of coal originate in former wetlands called coal forests that covered much of the Earth's tropical land areas during the late Carboniferous ( Pennsylvanian) and Permian times. Many significant coal deposits are younger than this and originate from the Mesozoic and Cenozoic eras. Coal is used primarily as a fuel. While coal has been known and used for thousands of years, its usage was limited until the Industrial Revolution. With the invention of the steam engine, coal consumption increased. In 2020, coal supplied about a quarter of the world's primary energy and over a third of its electricity. Some iron ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Petroleum
Petroleum, also known as crude oil, or simply oil, is a naturally occurring yellowish-black liquid mixture of mainly hydrocarbons, and is found in geological formations. The name ''petroleum'' covers both naturally occurring unprocessed crude oil and petroleum products that consist of refined crude oil. A fossil fuel, petroleum is formed when large quantities of dead organisms, mostly zooplankton and algae, are buried underneath sedimentary rock and subjected to both prolonged heat and pressure. Petroleum is primarily recovered by oil drilling. Drilling is carried out after studies of structural geology, sedimentary basin analysis, and reservoir characterisation. Recent developments in technologies have also led to exploitation of other unconventional reserves such as oil sands and oil shale. Once extracted, oil is refined and separated, most easily by distillation, into innumerable products for direct use or use in manufacturing. Products include fuels such as gasol ...

Strategist
A strategist is a person with responsibility for the formulation and implementation of a strategy. Strategy generally involves setting goals, determining actions to achieve the goals, and mobilizing resources to execute the actions. A strategy describes how the ends (goals) will be achieved by the means (resources). The senior leadership of an organization is generally tasked with determining strategy. Strategy can be intended or can emerge as a pattern of activity as the organization adapts to its environment or competes. It involves activities such as strategic planning and strategic thinking. Types of strategists by field The strategy role exists in a variety of organizations and fields of study. In large corporations, strategic planners or corporate financial planning and analysis (FP&A) personnel are involved in the formulation and implementation of the organization's strategy. The strategy is typically set by business leaders such as the chief executive officer and key ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Red Star Over China
''Red Star Over China'' is a 1937 book by Edgar Snow. It is an account of the Chinese Communist Party (CCP) that was written when it was a guerrilla army and still obscure to Westerners. Along with Pearl S. Buck's ''The Good Earth'' (1931), it was the most influential book on Western understanding of China as well as the most influential book on Western sympathy for Red China in the 1930s. Overview In ''Red Star Over China'', Edgar Snow recounts the months that he spent with the Chinese Red Army in 1936. Most of this time, he was at their then-capital Bao'an (Pao An). They moved to the famous Yan'an only after he left. Snow uses his extensive interviews with Mao and the other top leaders to present vivid descriptions of the Long March, as well as biographical accounts of leaders on both sides of the conflicts, including Zhou Enlai, Peng Dehuai, Lin Biao, He Long, and Mao Zedong's own account of his life. When Snow wrote, there were no reliable reports reaching the West ... [...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 location. ...
