Xituanshan
Xituanshan ( zh, c=西团山, p=Xī tuánshān, ) is a Late Bronze Age group of stone burials in Jilin, China. It was designated a Major National Historical and Cultural Site by the Chinese government in 2001. The site gave its name to a particular style of objects and architecture called the Xituanshan Culture, distributed throughout Jilin, Changchun and southern Heilongjiang. Site Xituanshan is a low-lying granite mountain to the west of Jilin City that faces Dongtuanshan across the Songhua River. Together, the two mountains were referred to in the past as the twin tuanshan peaks ( zh, c=团山相峙). The site comprises 11 gulleys on Xituanshan's southwest slope, over which nine stone cist tombs are distributed. On excavation, various stone tools, pottery pieces, pig jaws, and pig tusks were found. In two graves, remains of plant seeds were found in pots: Setaria lutescens and Eriochloa villosa have been suggested to be wild ancestors of Foxtail millet and Broomcorn mill ...

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 ...

China
China, officially the People's Republic of China (PRC), is a country in East Asia. It is the world's most populous country, with a population exceeding 1.4 billion, slightly ahead of India. China spans the equivalent of five time zones and borders fourteen countries by land, the most of any country in the world, tied with Russia. Covering an area of approximately , it is the world's third largest country by total land area. The country consists of 22 provinces, five autonomous regions, four municipalities, and two Special Administrative Regions (Hong Kong and Macau). The national capital is Beijing, and the most populous city and financial center is Shanghai. Modern Chinese trace their origins to a cradle of civilization in the fertile basin of the Yellow River in the North China Plain. The semi-legendary Xia dynasty in the 21st century BCE and the well-attested Shang and Zhou dynasties developed a bureaucratic political system to serve hereditary monarchies, or dyna ...

History Of Manchuria
Manchuria is a region in East Asia. Depending on the definition of its extent, "Manchuria" can refer either to a region falling entirely within present-day China, or to a larger region today divided between Northeast China and the Russian Far East. To differentiate between the two parts following the latter definition, the Russian part is also known as Outer Manchuria, while the Chinese part is known as Inner Manchuria. Manchuria is the homeland of the Manchu people. "Manchu" is a name introduced by Hong Taiji of the Qing dynasty in 1636 for the Jurchen people, a Tungusic people. The population grew from about 1 million in 1750 to 5 million in 1850 and to 14 million in 1900, largely because of the immigration of Han farmers. Lying at the juncture of the Chinese, Japanese and Russian spheres of influence, Manchuria has been a hotbed of conflict since the late-19th century. The Russian Empire established control over the northern part of Manchuria in 1860 ( Beijing Treaty); it b ...

Common Era
Common Era (CE) and Before the Common Era (BCE) are year notations for the Gregorian calendar (and its predecessor, the Julian calendar), the world's most widely used calendar era. Common Era and Before the Common Era are alternatives to the original Anno Domini (AD) and Before Christ (BC) notations used for the same calendar era. The two notation systems are numerically equivalent: " CE" and "AD " each describe the current year; "400 BCE" and "400 BC" are the same year. The expression traces back to 1615, when it first appeared in a book by Johannes Kepler as the la, annus aerae nostrae vulgaris (), and to 1635 in English as " Vulgar Era". The term "Common Era" can be found in English as early as 1708, and became more widely used in the mid-19th century by Jewish religious scholars. Since the later 20th century, BCE and CE have become popular in academic and scientific publications because BCE and CE are religiously neutral terms. They are used by others who wish to be sensit ...

Radiocarbon Dating
Radiocarbon dating (also referred to as carbon dating or carbon-14 dating) is a method for determining the age of an object containing organic material by using the properties of radiocarbon, a radioactive isotope of carbon. The method was developed in the late 1940s at the University of Chicago by Willard Libby. It is based on the fact that radiocarbon () is constantly being created in the Earth's atmosphere by the interaction of cosmic rays with atmospheric nitrogen. The resulting combines with atmospheric oxygen to form radioactive carbon dioxide, which is incorporated into plants by photosynthesis; animals then acquire by eating the plants. When the animal or plant dies, it stops exchanging carbon with its environment, and thereafter the amount of it contains begins to decrease as the undergoes radioactive decay. Measuring the amount of in a sample from a dead plant or animal, such as a piece of wood or a fragment of bone, provides information that can be used to calc ...

Pottery Vessels Excavated From Houshishan, Jilin City
Pottery is the process and the products of forming vessels and other objects with clay and other ceramic materials, which are fired at high temperatures to give them a hard and durable form. Major types include earthenware, stoneware and porcelain. The place where such wares are made by a ''potter'' is also called a ''pottery'' (plural "potteries"). The definition of ''pottery'', used by the ASTM International, is "all fired ceramic wares that contain clay when formed, except technical, structural, and refractory products". In art history and archaeology, especially of ancient and prehistoric periods, "pottery" often means vessels only, and sculpted figurines of the same material are called "terracottas". Pottery is one of the oldest human inventions, originating before the Neolithic period, with ceramic objects like the Gravettian culture Venus of Dolní Věstonice figurine discovered in the Czech Republic dating back to 29,000–25,000 BC, and pottery vessels that were ...

Jar Burial
Jar burials are human burials where the corpse is placed into a large earthenware and then is interred. Jar burials are a repeated pattern at a site or within an archaeological culture. When an anomalous burial is found in which a corpse or cremated remains have been interred, it is not considered a "jar burial". Jar burial can be traced to various regions across the globe. It is noted to have been practiced as early as BCE 4500, and as recent as CE 15–17th centuries. Particular areas of studies on jar burial excavations include India, Indonesia, Lebanon, Palestine, Taiwan, Japan, Cambodia, Iran, Syria, Sumatra, Egypt, Malaysia, the Philippines, Thailand, Vanuatu, and Vietnam. These differing locations call for different methods, accoutrements, and rationales behind the jar burial practices. Cultural practices ranged from primary versus secondary burial, burial offerings (bronze/iron tools, weapons and bronze/silver/gold ornaments, wood, stone, clay, glass, and paste) in/aro ...

Promontories
A promontory is a raised mass of land that projects into a lowland or a body of water (in which case it is a peninsula). Most promontories either are formed from a hard ridge of rock that has resisted the erosive forces that have removed the softer rock to the sides of it, or are the high ground that remains between two river valleys where they form a confluence. A headland, or head, is a type of promontory. Promontories in history Located at the edge of a landmass, promontories offer a natural defense against enemies, as they are often surrounded by water and difficult to access. Many ancient and modern forts and castles have been built on promontories for this reason. One of the most famous examples of promontory forts is the Citadel of Namur in Belgium. Located at the confluence of the Meuse and Sambre rivers, the citadel has been a prime fortified location since the 10th century. The surrounding rivers act as a natural moat, making it difficult for enemies to access the for ...

Soil Creep
Downhill creep, also known as soil creep or commonly just creep, is a type of creep characterized by the slow, downward progression of rock and soil down a low grade slope; it can also refer to slow deformation of such materials as a result of prolonged pressure and stress. Creep may appear to an observer to be continuous, but it really is the sum of numerous minute, discrete movements of slope material caused by the force of gravity. Friction, being the primary force to resist gravity, is produced when one body of material slides past another offering a mechanical resistance between the two which acts to hold objects (or slopes) in place. As slope on a hill increases, the gravitational force that is perpendicular to the slope decreases and results in less friction between the material that could cause the slope to slide. Overview Water is a very important factor when discussing soil deformation and movement. For instance, a sandcastle will only stand up when it is made with da ...

Retaining Wall
Retaining walls are relatively rigid walls used for supporting soil laterally so that it can be retained at different levels on the two sides. Retaining walls are structures designed to restrain soil to a slope that it would not naturally keep to (typically a steep, near-vertical or vertical slope). They are used to bound soils between two different elevations often in areas of terrain possessing undesirable slopes or in areas where the landscape needs to be shaped severely and engineered for more specific purposes like hillside farming or roadway overpasses. A retaining wall that retains soil on the backside and water on the frontside is called a seawall or a bulkhead. Definition A wall for holding in place a mass of earth or the like, as at the edge of a terrace or excavation. A retaining wall is a structure designed and constructed to resist the lateral pressure of soil, when there is a desired change in ground elevation that exceeds the angle of repose of the soil. A basement ...
