I though that Dao Bach Long Vy have educated you about 2000-year-old sovereignty in another topic. The ''maps'' you posted are only for fun, not the evidences. Now you repeat 2000-year-old sovereignty here. It is very pity.
How did Chinese galleons navigate the South China Sea if they didn't create ancient maps (like the ones below)?
Your stupid claim of fake Chinese maps makes no sense.
The South China Sea issue is pretty simple. We have physical proof of shipwrecked 12th and 13th century Chinese ships (from the Song and Yuan Dynasties) near the Paracel Islands. We also have a French-discovered 15th century Chinese galleon shipwreck off the coast of Brueni.
We know for a fact that China has been sailing, mapping, fishing, trading, and using the South China Sea islands and maritime territories at least as far back as the 12th or 15th century.
As far as I know, the advanced Chinese ocean sailing technology did not exist in Vietnam or the Philippines. Unless you Viets or Filipinos can point to a single ancient shipwreck, the evidence proves that you were technologically backward and landlocked.
You Viets and Filipinos could probably build a few simple rafts, but your people most certainly could not sail throughout the South China Sea like ancient Chinese.
The evidence points to only one conclusion. China is the first to discover, map, sail, claim, and use the South China Sea islands and maritime territories.

Spratly Islands have belonged to China since ancient times
Ocean-faring Chinese explorers had claimed the Spratly Islands a thousand years ago.
[Source: Wikipedia article on Spratly Islands with primary sources listed in footnotes]
"Ancient Chinese maps record the "Thousand Li Stretch of Sands"; Qianli Changsha (千里長沙
and the "Ten-Thousand Li of Stone Pools"; Wanli Shitang (萬里石塘
,[7] which China today claims refers to the Spratly Islands. The Wanli Shitang have been explored by the Chinese since the Yuan Dynasty and may have been considered by them to have been within their national boundaries. [8][9] They are also referenced in the 13th century,[10] followed by the Ming Dynasty.[11] When the Ming Dynasty collapsed, the Qing Dynasty continued to include the territory in maps compiled in 1724,[12] 1755,[13] 1767,[14] 1810,[15] and 1817.[16] A Vietnamese map from 1834 also includes the Spratly Islands clumped in with the Paracels (a common occurrence on maps of that time) labeled as "Wanli Changsha".[17]"
By the twelfth century, names for the South China Sea islands began to appear. The Paracels and the Spratlys were referred to more consistently as Changsha and Shitang. By the mid-fourteenth century, Shitang could be accurately identified as the Spratlys. There is also evidence of Chinese naval control over some areas of the South China Sea, which resulted in complete Chinese dominion of the South China Sea in the late thirteenth century. Finally, in the fifteenth century, Zheng He's seven voyages placed the South China Sea islands on the official navigational charts. In this map, the Xisha Islands are called Shitang, and the Nansha Islands are referred to as Wansheng Shitang Yu.
The Map of South and East Ocean Sea Routes was drawn in between 1712-1721 by Qing (Ching) Dynasty Fujian (Fuchien) Province Navy Commander Shi Shibiao, the son of a famous Qing Dynasty imperial officer. This map clearly shows the sea routes, time, and descriptions from Chinese coastal ports to Japan, Laos, Vietnam, Indonesia, Brunei, Cambodia and the Philippines. On this map, the locations and names of the Southern Sea Islands (Nanhai Zhudao) are very accurate. The map shows Chinese sovereignty over the South China Sea islands (including Nansha Islands, Xisha Islands, Zhongsha Islands and Dongsha Islands).
1834 Vietnamese map showed the islands as Chinese "Wanli Changsha."
