Liaoning is a northeastern province of the People's Republic of China. Its one-character abbreviation is Liao.
"Liáo" is an ancient name for this region, which was adopted by the Liao Dynasty (Khitan Empire) which ruled this area between 907 and 1125. "Níng" means "peacefulness". The modern province was established in 1907 as Fengtian province and the name was changed to Liaoning in 1929. Under the Japanese puppet Manchukuo regime, the province reverted to its old name, but the name Liaoning was restored in 1945.
Liaoning is located in the southern part of China's Northeast. Liaoning borders the Yellow Sea (Korea Bay) and the Bohai Gulf in the south, North Korea in the southeast, Jilin Province to the northeast, Hebei Province to the west, and Inner Mongolia to the northwest.
The Yalu River marks the border between North Korea and the Chinese provinces of Jilin and Liaoning. It empties into the Korea Bay between Dandong (Liaoning) and Sin?iju (North Korea). It is possible to think of Liaoning as three approximate geographical regions: the highlands in the west, plains in the middle, and hills in the east.
The highlands in the west are dominated by the Nulu'erhu Mountains, which roughly follow the border between Liaoning and Inner Mongolia. The entire region is dominated by low hills.
The central part of Liaoning consists of the watersheds of rivers such as the Liao, Daliao, and their tributaries. This region is mostly flat and at low altitudes.
The eastern part of Liaoning is dominated by the Changbai Shan and Qian Shan ranges, which extends into the sea to form the Liaodong Peninsula. The highest point in Liaoning, Mount Huabozi (1336 m), is found in this region.
Liaoning has a continental monsoon climate, and rainfall averages to about 440 to 1130 mm annually. Summer is rainy while the other seasons are dry. |
