Dunhuang Cave 16
Dunhuang () is a county-level city in Northwestern Gansu Province, Western China. According to the 2010 Chinese census, the city has a population of 186,027, though 2019 estimates put the city's population at about 191,800. Dunhuang was a major stop on the ancient Silk Road and is best known for the nearby Mogao Caves. Dunhuang is situated in an oasis containing Crescent Lake and Mingsha Shan (, meaning "Singing-Sand Mountain"), named after the sound of the wind whipping off the dunes, the singing sand phenomenon. Dunhuang commands a strategic position at the crossroads of the ancient Southern Silk Route and the main road leading from India via Lhasa to Mongolia and Southern Siberia, and also controls the entrance to the narrow Hexi Corridor, which leads straight to the heart of the north Chinese plains and the ancient capitals of Chang'an (today known as Xi'an) and Luoyang. Administratively, the county-level city of Dunhuang is part of the prefecture-level city of Jiuquan. His ...

Silk Route
The Silk Road () was a network of Eurasian trade routes active from the second century BCE until the mid-15th century. Spanning over 6,400 kilometers (4,000 miles), it played a central role in facilitating economic, cultural, political, and religious interactions between the East and West. The name "Silk Road", first coined in the late 19th century, has fallen into disuse among some modern historians in favor of Silk Routes, on the grounds that it more accurately describes the intricate web of land and sea routes connecting East and Southeast Asia, the Indian subcontinent, Central Asia, the Middle East, East Africa and Europe. The Silk Road derives its name from the highly lucrative trade of silk textiles that were produced almost exclusively in China. The network began with the Han dynasty's expansion into Central Asia around 114 BCE, which largely pacified the once untamed region. Imperial envoy Zhang Qian was commissioned to explore the unknown lands beyond the region in s ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Yuezhi
The Yuezhi (;) were an ancient people first described in Chinese histories as nomadic pastoralists living in an arid grassland area in the western part of the modern Chinese province of Gansu, during the 1st millennium BC. After a major defeat at the hands of the Xiongnu in 176 BC, the Yuezhi split into two groups migrating in different directions: the Greater Yuezhi (''Dà Yuèzhī'' 大月氏) and Lesser Yuezhi (''Xiǎo Yuèzhī'' 小月氏). This started a complex domino effect that radiated in all directions and, in the process, set the course of history for much of Asia for centuries to come. The Greater Yuezhi initially migrated northwest into the Ili River, Ili Valley (on the modern borders of China and Kazakhstan), where they reportedly displaced elements of the Sakas. They were driven from the Ili Valley by the Wusun and migrated southward to Sogdia and later settled in Bactria. The Greater Yuezhi have consequently often been identified with peoples mentioned in classica ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Qiang (historical People)
Qiang () was a name given to various groups of people at different periods in ancient China. The Qiang people are generally thought to have been of Tibeto-Burman origin, though there are other theories. The Tangut people of the Tang, Sung and Yuan dynasties may be of Qiang descent. The modern Qiang people as well as Tibetans may also have been descended in part from the ancient Qiangs. Etymology According to the Han dynasty dictionary ''Shuowen Jiezi'', the Qiang were shepherds, and the Chinese character for Qiang () was thus formed from the characters for "sheep" (羊) and "man" (人), and pronounced like "sheep".Shouwen Original text: 羌:西戎牧羊人也。从人从羊,羊亦聲。 '''' also men ...

Summer Vacation 2007, 263, Watchtower In The Morning Light, Dunhuang, Gansu Province
Summer is the Heat, hottest of the four temperate seasons, occurring after Spring (season), spring and before autumn. At or centred on the summer solstice, the earliest sunrise and latest sunset occurs, daylight hours are longest and dark hours are shortest, with day length decreasing as the season progresses after the solstice. The date of the beginning of summer varies according to climate, tradition, and culture. When it is summer in the Northern Hemisphere, it is winter in the Southern Hemisphere, and vice versa. Timing From an astronomical view, the equinoxes and solstices would be the middle of the respective seasons, but sometimes astronomical summer is defined as starting at the solstice, the time of maximal insolation, often identified with the 21st day of June or December. By solar reckoning, summer instead starts on May Day and the summer solstice is Midsummer. A variable seasonal lag means that the meteorology, meteorological centre of the season, which is base ...

Geography (Ptolemy)
The ''Geography'' ( grc-gre, Γεωγραφικὴ Ὑφήγησις, ''Geōgraphikḕ Hyphḗgēsis'', "Geographical Guidance"), also known by its Latin names as the ' and the ', is a gazetteer, an atlas, and a treatise on cartography, compiling the geographical knowledge of the 2nd-century Roman Empire. Originally written by Claudius Ptolemy in Greek at Alexandria around AD 150, the work was a revision of a now-lost atlas by Marinus of Tyre using additional Roman and Persian gazetteers and new principles. Its translation into Arabic in the 9th century and Latin in 1406 was highly influential on the geographical knowledge and cartographic traditions of the medieval Caliphate and Renaissance Europe. Manuscripts Versions of Ptolemy's work in antiquity were probably proper atlases with attached maps, although some scholars believe that the references to maps in the text were later additions. No Greek manuscript of the ''Geography'' survives from earlier than the 13th ce ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Ptolemy
Claudius Ptolemy (; grc-gre, Πτολεμαῖος, ; la, Claudius Ptolemaeus; AD) was a mathematician, astronomer, astrologer, geographer, and music theorist, who wrote about a dozen scientific treatises, three of which were of importance to later Byzantine, Islamic, and Western European science. The first is the astronomical treatise now known as the '' Almagest'', although it was originally entitled the ''Mathēmatikē Syntaxis'' or ''Mathematical Treatise'', and later known as ''The Greatest Treatise''. The second is the ''Geography'', which is a thorough discussion on maps and the geographic knowledge of the Greco-Roman world. The third is the astrological treatise in which he attempted to adapt horoscopic astrology to the Aristotelian natural philosophy of his day. This is sometimes known as the ''Apotelesmatika'' (lit. "On the Effects") but more commonly known as the '' Tetrábiblos'', from the Koine Greek meaning "Four Books", or by its Latin equivalent ''Quadrip ...

Guazhou County
Guazhou County (), formerly (until 2006) Anxi County () or Ansichow, is a county in the northwest of Gansu province, the People's Republic of China. It is under the administration of Jiuquan City. History Emperor Wudi (140-87 BCE) had the Great Wall extended northwestward all the way to the Gate of Jade (Yumen Pass), the westernmost garrison town near Dunhuang. He then set up a system of garrisons all along this part of the Great Wall and put its headquarters in a town called Anxi (“Tranquil West”) and where the northern and southern Silk Routes historically diverged." The name Guazhou (land/prefecture of melons) has a long contentious history; the name first appeared in records from the Warring States period, but Chinese historians have debated (since the 3rd century) whether it referred to a region in modern-day Gansu or Shaanxi. From Northern Wei to Sui dynasty, Guazhou Prefecture contained both modern-day Dunhuang and Guazhou counties; in the Tang dynasty, the ...

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 munici ...

Chang'an
Chang'an (; ) is the traditional name of Xi'an. The site had been settled since Neolithic times, during which the Yangshao culture was established in Banpo, in the city's suburbs. Furthermore, in the northern vicinity of modern Xi'an, Qin Shi Huang of the Qin dynasty, China's first emperor, held his imperial court, and constructed his massive mausoleum guarded by the Terracotta Army. From its capital at Xianyang, the Qin dynasty ruled a larger area than either of the preceding dynasties. The imperial city of Chang'an during the Han dynasty was located northwest of today's Xi'an. During the Tang dynasty, the area that came to be known as Chang'an included the area inside the Ming Xi'an fortification, plus some small areas to its east and west, and a substantial part of its southern suburbs. Thus, Tang Chang'an was eight times the size of the Ming Xi'an, which was reconstructed upon the site of the former imperial quarters of the Sui and Tang city. During its heyday, Chang'an w ...

Hexi Corridor
The Hexi Corridor (, Xiao'erjing: حْسِ ظِوْلاْ, IPA: ), also known as the Gansu Corridor, is an important historical region located in the modern western Gansu province of China. It refers to a narrow stretch of traversable and relatively arable plain west of the Yellow River's Ordos Loop, flanked between the much more elevated and inhospitable terrains of the Mongolian and Tibetan Plateaus. The name ''Hexi'', refers to "west of the river". As part of the Northern Silk Road, running northwest from the western section of the Ordos Loop between Yinchuan and Lanzhou, the Hexi Corridor was the most important trade route in Northwest China. It linked China ''proper'' to the historic Western Regions for traders and military incursions into Central Asia. It is a string of oases along the northern edges of the Qilian Mountains and Altyn-Tagh, with the high and desolate Tibetan Plateau further to the south. To the north are the Longshou, Heli and Mazong Mountains separatin ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
