Яньтай Провинция Шаньдун

Yantai is currently the second largest industrial city in Shandong, next only to Qingdao. The contemporary name of Yantai came from the watchtowers constructed on Mount Qi in 1398, during the reign of the Hongwu Emperor, founding emperor of the Ming Dynasty (yan—smoke; tai—tower). The towers served to raise alarms against invasions of Japanese pirates.
