YINCHUAN, CHINA—Nine sections of the Great Wall have been found along the border of northwest China’s Ningxia Hui Autonomous Region and Gansu Province. “Finally, we’re able to see the whole picture of the Qin Great Wall,” Zhou Xinghua, a former curator of the Museum of Ningxia Hui Autonomous Region told China Daily. Six of the sections are on the southern bank of the Yellow River, and stretch between Nanchangtan Village in Ningxia and Jingyuan County in Gansu. The wall would have prevented invaders from crossing the river when it was frozen. The other three sections are in Jingyuan County.
