In order to avoid the phenomenon of duplicate names for ships, the granting of naval ship names must be strictly divided by region. Namely:

The area under the jurisdiction of the North Sea Fleet uses the place names of fourteen provinces (municipalities and autonomous regions) including North China, Northeast China, and Northwest China: Liaoning, Jilin, Heilongjiang, Inner Mongolia, Qinghai, Gansu, Ningxia, Shaanxi, Shanxi, and Beijing , Tianjin, Hebei, Shandong, and Henan;

The jurisdiction of the East China Sea Fleet uses the place names of the seven provinces (municipalities and autonomous regions) in East China: Shanghai, Jiangsu, Zhejiang, Anhui, Fujian, Jiangxi, Hubei, and Xinjiang;

p>

The jurisdiction of the South China Sea Fleet uses the place names of nine provinces (municipalities and autonomous regions) in South China and Southwest China: Hunan, Guangdong, Guangxi, Hainan, Sichuan, Chongqing, Guizhou, Yunnan, and Tibet.

However, there are exceptions, such as the landing of the 169 "Wuhan", the 170 "Lanzhou" destroyer, the 533 "Taizhou", the 569 "Yuncheng" frigate, and the 945 "Huashan" belonging to the South China Sea Fleet. The names of the ships are not the place names of South China and Southwest China. The frigates No. 559 "Foshan" and No. 566 "Huaihua" belong to the East China Sea Fleet and are the place names of Guangdong and Hunan provinces.
