The city's name ""Qinhuangdao"" literally means "Qin Emperor island", and is allegedly originated from the legend that the Jieshishan Scenic Area in Changli County was the site of First Emperor of Qin's famous ritual during his fourth and final survey tour to the east in 210 BC. The "island" refers to the Nanshan area of the Port of Qinhuangdao at the southern edge of the city's Haigang District, which used to be a small offshore island until the late Qing dynasty, when dumping of dredged silt joined it to the mainland after the Guangxu Emperor approved the port's construction in the late 19th century.
