According to the historical documents about Diaoyu Island in the early Ming Dynasty, Diaoyu Island was under the jurisdiction of Okinawa Prefecture and became independent about 125 years ago. Before the annexation of Ryukyu, it had contact with about 500 friends of Ryukyu. Diaoyu Island was first discovered and named, and the book "Send with the Wind" in the Ming Dynasty recorded the fishing of the island.

Navigators have learned about the history of the second knighthood in the Qing Dynasty in the trough area south of Diaoyu Island and the dividing line between Qing Dynasty and Ryukyu. Wang Ting 1683 went to Ryukyu and wrote Miscellaneous Notes on Making Ryukyu. In the fifth volume of this book, it is recorded that the ship passed through Diaoyu Island and chiwei yu to avoid the shipwreck, and informed the trough (called suburb or ditch) that the outside world 1756 was heading for Ryukyu. Huang Zhou mentioned Wang Ting in the sixteenth volume of his Notes on Ryukyu.

It shows that the Ming and Qing governments looked directly at the Diaoyu Islands territory until October of the 19th year of Guangxu in Qing Dynasty (1893), that is, before the Sino-Japanese War. The imperial edict says that the pills Sheng Xuanhuai took are very effective.
