Liaodong PeninsulaThe Liaodong or Liaotung Peninsula () is a peninsula in southern Liaoning province in Northeast China, and makes up the southwestern coastal half of the Liaodong region. It is located between the mouths of the Daliao River (the historical lower section of the Liao River) in the west and the Yalu River in the east, and encompasses the territories of the whole sub-provincial city of Dalian and parts of prefectural cities of Yingkou, Anshan and Dandong.
GoryeoGoryeo (; ko.ɾjʌ) was a Korean state founded in 918, during a time of national division called the Later Three Kingdoms period, that unified and ruled the Korean Peninsula until 1392. Goryeo achieved what has been called a "true national unification" by Korean historians as it not only unified the Later Three Kingdoms but also incorporated much of the ruling class of the northern kingdom of Balhae, who had origins in Goguryeo of the earlier Three Kingdoms of Korea.
Jurchen peopleJurchen (Manchu: Jušen, dʒuʃən; 女真, Nǚzhēn nü3.zhen1) is a term used to collectively describe a number of East Asian Tungusic-speaking people, descended from the Donghu people. They lived in northeastern China, also known as Manchuria, before the 18th century. The Jurchens were renamed Manchus in 1635 by Hong Taiji. Different Jurchen groups lived as hunter-gatherers, pastoralist semi-nomads, or sedentary agriculturists.
Manchu languageManchu (Manchu:, Romanization: manju gisun) is a critically endangered East Asian Tungusic language native to the historical region of Manchuria in Northeast China. As the traditional native language of the Manchus, it was one of the official languages of the Qing dynasty (1636–1912) of China, although today the vast majority of Manchus speak only Mandarin Chinese. Several thousand can speak Manchu as a second language through governmental primary education or free classes for adults in classrooms or online.
LiaoningLiaoning ljau'nIN () is a coastal province in Northeast China that is the smallest, southernmost, and most populous province in the region. With its capital at Shenyang, it is located on the northern shore of the Yellow Sea, and is the northernmost coastal province of the People's Republic of China. Historically a gateway between China proper and Manchuria, the modern Liaoning province was established in 1907 as Fengtian or Fengtien province and was renamed Liaoning in 1929.
Jet aircraftA jet aircraft (or simply jet) is an aircraft (nearly always a fixed-wing aircraft) propelled by jet engines. Whereas the engines in propeller-powered aircraft generally achieve their maximum efficiency at much lower speeds and altitudes, jet engines achieve maximum efficiency at speeds close to or even well above the speed of sound. Jet aircraft generally cruise most efficiently at about Mach 0.8 () and at altitudes around or more. The idea of the jet engine was not new, but the technical problems involved could not begin to be solved until the 1930s.
JilinJilin dʒiːˈlɪn (; alternately romanized as Kirin or Chilin) is one of the three provinces of Northeast China. Its capital and largest city is Changchun. Jilin borders North Korea (Rasŏn, North Hamgyong, Ryanggang and Chagang) and Russia (Primorsky Krai) to the east, Heilongjiang to the north, Liaoning to the south, and Inner Mongolia to the west. Along with the rest of Northeast China, Jilin underwent an early period of industrialization. However, Jilin's economy, characterized by heavy industry, has been facing economic difficulties with privatization.
DogfightA dogfight, or dog fight, is an aerial battle between fighter aircraft conducted at close range. Modern terminology for air-to-air combat is air combat manoeuvring (ACM), which refers to tactical situations requiring the use of individual basic fighter maneuvers (BFM) to attack or evade one or more opponents. This differs from aerial warfare, which deals with the strategy involved in planning and executing various missions. Dogfighting first occurred during the Mexican Revolution in 1913, shortly after the invention of the airplane.
Korean Armistice AgreementThe Korean Armistice Agreement (한국정전협정 / 조선정전협정; ) is an armistice that brought about a complete cessation of hostilities of the Korean War. It was signed by United States Army Lieutenant General William Harrison Jr. and General Mark W. Clark representing the United Nations Command (UNC), North Korea leader Kim Il Sung and General Nam Il representing the Korean People's Army (KPA), and Peng Dehuai representing the Chinese People's Volunteer Army (PVA).
