The mission is completed in December of the same year. In honor of the actions of Taiping Ship and Yongxing ship, Chang Island (長島) is renamed to Taiping Island (太平島), and the Lin Island (林島) is renamed to Yongxing Island (永興島) under orders. The Xiniao Island (西鳥島) is also called Spratly Island. Because it is located in the far south, so the Goverment renames it to Nanwei Island (南威島). The Ministry of the Interior adjusted the names of the islands according to their locations in the South China Sea, so changed Tuansha Islands (團沙群島) (i.e. Xinnan Islands (新南群島) by Japanese, Spratly Islands by Westerners) to Nansha Islands (南沙群島), and the former Japanese Nansha Islands (南沙群島) is renamed to Zhongsha Islands (中沙群島). The other islands and reefs are named after the historical diplomats to the Nanyang, in memory of them."
