Abstract:
Since the Dai-min ittou shi (Mdr. Da-Ming yitong zhi, Records of the United Great Min), which presents the Empire's geography of 1461, all Chinese geographic records have clearly stated that Chinese territory officially extends only to the east to the mainland coast and to the south to the southern tip of the Kainan (Mdr. Hainan) Island. Records have also stated that Taiwan Prefecture territory officially extends only to Fort Keelung and Cape Santiago, or the north and north-east tips of Taiwan Island, respectively.
 Most Ryukyu officials providing navigation services descended from 36 families naturalized in Ryukyu from Fukken (Mdr. Fujian). But Koumin Jitsuroku (Mdr. Huangiming shilu) clearly stated in January 1547 that the emperor officially deemed them non-Min Empire nationals. This was only natural, as the Empire credo from earlier times had been ban to sail abroad to sea.
 The 17th century's Funanori-piroto (Sailor Pilot), a record of Shogunate-chartered ships era, presents the Senkakus as part of a north-south shipping route from Nagasaki to Luzon via the east coast of Taiwan, with no connection with China.
