The North China Plain (simplified Chinese: 华北平原; traditional Chinese: 華北平原; pinyin: Huáběi Píngyuán) is based on the deposits of the Yellow River and is the largest alluvial plain of eastern Asia. The plain is bordered on the north by the Yanshan Mountains and on the west by the Taihang Mountains edge of the Shanxi ('western mountains') plateau. To the south, it merges into the Yangtze Plain. From northeast to southeast, it fronts the Bohai Sea, the highlands of Shandong Peninsula, and the Yellow Sea.
