Wúdì

Wudi lies on the low salt coast of northern Shandong, facing the Bohai Sea, where ancient shell ridges mark old shorelines. The name belongs to the oldest geography of Qi: in the Zuo Zhuan the Qi minister Guan Zhong claimed the land as far as Wudi to the north. The historical Wudi county stood elsewhere; the Ming town here was Haifeng. Its present site was walled in 1357 near the end of the Yuan, and in 1373 the Ming set up Haifeng County with its seat there, an arrangement the Qing kept.
