Longxi Commandery
Longxi Commandery ( Chinese:  trad. , simp. , ''Lǒngxījùn'') was a commandery of imperial China in present-day Gansu, named due to its location west of Mount Long (the southern portion of Mount Liupan). Qin dynasty Established by Shi Huangdi, it originally covered the entire territory of the Qin Empire west of Mount Long with its seat at Didao (present-day Taoyang in Lintao County). This area included most of the upper Wei valley. Its principal route of communication was the Long Road (named for the mountain), which probably passed along the course of the modern railroad west from Xi'an although much of the area nearest the river was then marshland. The territory was used as a staging ground for campaigns up the Tao and the upper Yellow River.De Crespigny, Rafe.The Government and Geography of the Northern Frontier of Late Han!--sic-->".

Chinese Language
Chinese ( or ) is a group of languages spoken natively by the ethnic Han Chinese majority and List of ethnic groups in China, many minority ethnic groups in China, as well as by various communities of the Chinese diaspora. Approximately 1.39 billion people, or 17% of the global population, speak a variety of Chinese as their first language. Chinese languages form the Sinitic languages, Sinitic branch of the Sino-Tibetan language family. The spoken varieties of Chinese are usually considered by native speakers to be dialects of a single language. However, their lack of mutual intelligibility means they are sometimes considered to be separate languages in a Language family, 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 Chinese, Mandarin with 66%, or around 800&nb ...

Xiongnu
The Xiongnu (, ) were a tribal confederation of Nomad, nomadic peoples who, according to ancient Chinese historiography, Chinese sources, inhabited the eastern Eurasian Steppe from the 3rd century BC to the late 1st century AD. Modu Chanyu, the supreme leader after 209 BC, founded the Xiongnu Empire. After overthrowing their previous overlords, the Yuezhi, the Xiongnu became the dominant power on the steppes of East Asia, centred on the Mongolian Plateau. The Xiongnu were also active in areas now part of Siberia, Inner Mongolia, Gansu and Xinjiang. Their relations with the Chinese dynasties to the south-east were complex—alternating between various periods of peace, war, and subjugation. Ultimately, the Xiongnu were defeated by the Han dynasty in a Han–Xiongnu Wars, centuries-long conflict, which led to the confederation splitting in two, and forcible resettlement of large numbers of Xiongnu within Han borders. During the Sixteen Kingdoms era, listed as one of the "Fi ...

Empress Lü Zhi
The word ''emperor'' (from , via ) can mean the male ruler of an empire. ''Empress'', the female equivalent, may indicate an emperor's wife (empress consort), mother/grandmother (empress dowager/grand empress dowager), or a woman who rules in her own right and name (empress regnant or ''suo jure''). Emperors are generally recognized to be of the highest monarchic honour and rank, surpassing king. In Europe, the title of Emperor has been used since the Middle Ages, considered in those times equal or almost equal in dignity to that of Pope due to the latter's position as visible head of the Church and spiritual leader of the Catholic part of Western Europe. The emperor of Japan is the only currently reigning monarch whose title is translated into English as "Emperor". Both emperors and kings are monarchs or sovereigns, both emperor and empress are considered monarchical titles. In as much as there is a strict definition of emperor, it is that an emperor has no relations impl ...

Bailong River
The Bailong River () or Khuchu, Drukchu () is a 576km-long river in the Yangtze River basin. From its source to confluence with the Jialing River, the Bailong is actually longer and is thus the main stem of the Jialing River system. The scenic Jiuzhaigou reserve is found along one of the Bailong's tributaries. Two reservoirs have been constructed in Wen County ( Bikou Dam). The reservoirs serve to provide hydroelectricity, aquaculture, flood control, irrigation and for tourism development. History In August 2010, heavy rains triggered a mudslide that dammed the river in Zhugqu County, Gansu, causing extensive damage and killing over a thousand people. Course The Bailong River, in name, rises in Gansu's Luqu County, just west of the town of Langmusi. The river drains the northern sections of the Min Mountains and then flows through Zhugqu and Longnan before meeting the Jialing River in Guangyuan, Sichuan. The main stem of the river, however, is actually a tributary that ha ...
