Qingzhou

Qingzhou is a county-level city in the west of the Weifang prefecture, and its name is older than the city. It first appears in the Yu Gong chapter of the Book of Documents, which says that between the sea and Mount Tai there is Qingzhou, and so it was one of the nine provinces of ancient China. From the second century BC to the seventh it was the name of a whole region of north Shandong, and after that the name of a prefecture with its seat here. Six walled cities have stood on this ground since the Western Han, and the open part of the old town, about 1.4 square kilometres, is mostly the Nanyang city of the sixth century. It was named a national historical and cultural city in 2013.
