An Illustrated Compendium on Maritime Security (Chou Hai Tu Bian)

An Illustrated Compendium on Maritime Security (Chou Hai Tu Bian) compiled by geographer Zheng Ruozeng under the auspices of Hu Zongxian, Supreme Commander of the southeast coastal defenses of the Ming court, in 1561 (the 40th year of the reign of Emperor Jiajing of the Ming Dynasty), marked the islands under the jurisdiction of the Ming court's coastal defense forces. The book’s first volume, “A Map of Fujian’s Coastal Mountains and Islands (Fujian Yan Hai Shan Sha Tu)”, included Diaoyu Dao,Huangwei Yu and Chiwei Yu. This shows that by the Ming Dynasty at the latest, the islands were under the jurisdiction of China’s Maritime defense forces.
