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. The Yellow River flows through the middle of the plain into Bohai Sea.

The Great Wall of China is a series of fortifications made of stone, brick, tamped earth, wood, and other materials, generally built along an east-to-west line across the historical northern borders of China in part to protect the Chinese Empire or its prototypical states against intrusions by various nomadic groups or military incursions by various warlike peoples or forces. Several walls were being built as early as the 7th century BC;^[3] these, later joined together and made bigger and stronger, are now collectively referred to as the Great Wall.^[4] Especially famous is the wall built between 220–206 BC by the first Emperor of China, Qin Shi Huang. Little of that wall remains. Since then, the Great Wall has on and off been rebuilt, maintained, and enhanced; the majority of the existing wall is from the Ming Dynasty.
