Shanhai Pass
The Ming Great Wall crosses the northern part of Hebei and the eastern end is located on the coast at Shanhaiguan (Shanhai Pass), near Qinhuangdao. Informally known as the "First Pass of The World" (), Shanhaiguan was the place where Ming general Wu Sangui opened the gates to Manchu forces in 1644, beginning nearly 300 years of Manchu rule; Shanhai Pass also marks the psychological entrance / exit of Manchuria, so that for centuries Manchuria was known as "outside the Pass" or "east of the Pass". Beidaihe, located near Shanhaiguan, is a popular beach resort well known as a former meeting place for top governmental officials.
