Shangqiu
An ancient city in eastern Henan and the origin of Chinese commerce, with a uniquely preserved city wall and moat system at Shangqiu Ancient City.
Shangqiu lies in eastern Henan, where Henan, Shandong, Jiangsu and Anhui meet. It is regarded as one of the birthplaces of the Shang people and is also an important railway hub. Shangqiu Ancient City (the Guide Prefecture city) is famed for its "round outside, square inside" city wall and lake layout, and within the city are sites such as Yingtian Academy, the Tomb of Suihuang and Yanbo Terrace; Mangdang Mountain in Yongcheng holds the Han-dynasty Liang King tombs and relics of the Han dynasty's rise. Spring and autumn are the best times to visit. Shangqiu Station is where the Beijing–Hong Kong and Xuzhou–Lanzhou high-speed railways intersect, so transport is convenient.
