On May 21, the National Cutural Heritage Administration, the Ministry of Science and Technology, the People's Government of Hainan Province and the Chinese Academy of Sciences jointly held a press conference, officially announcing the discovery of large-scale ancient shipwrecked cultural relics in the northwest continental slope of the South China Sea, and the successful deployment of China's first underwater permanent mapping base point for deep-sea archaeology. At the same time, the National Cutural Heritage Administration officially launched the archaeological investigation of the No.1 and No.2 ancient shipwrecks on the northwest slope of the South China Sea. Netizens said, "With a long history of civilization, China, whether underground or underwater, contains rich and precious wealth." Opening a new chapter, "Amazing", "So many porcelain", "Just looking at the photos makes me feel excited", "It's too spectacular"... Under the live underwater photos of sunken ships published on Xinhua Weibo, netizens exclaimed. On May 20, National Cutural Heritage Administration took part in the first archaeological survey of the No.1 sunken ship on the northwest slope of the South China Sea in the manned submersible "Deep Sea Warrior", xinhuanet reported. On the southwest corner of the core accumulation area of the sunken ship site, permanent underwater surveying and mapping points were set up, and a preliminary search survey and video recording were carried out. The archaeological survey of the No.1 and No.2 ancient sunken ship sites on the northwest slope of the South China Sea was officially launched, Opening a new chapter in deep-sea archaeology in China. It is understood that the underwater permanent surveying base point deployed this time is carried by deep submersibles and placed on the surface of the seabed. After the deployment is completed, researchers can use the long baseline positioning system to calibrate the position of the permanent base point, laying a solid foundation for conducting precise archaeological investigations of ancient sunken ships. The "appearance" of two ancient shipwreck sites originated from last year's archaeological survey. CCTV News reported that in October 2022, a deep-sea archaeological survey team discovered two ancient sunken ships at a depth of approximately 1500 meters on the northwest slope of the South China Sea. One of the sunken ship sites is mainly made of porcelain, with an estimated number of cultural relics exceeding 100000. According to the preliminary judgment of the Shuishui cultural relic, it was named the sunken ship No.1 on the northwest slope of the South China Sea during the Zhengde period of the Ming Dynasty. The No. 2 sunken ship site is mainly composed of a large number of logs, and preliminary analysis suggests that it was an ancient sunken ship carrying goods from overseas to China. According to the preliminary judgment of the Shuishui cultural relic, it was named the sunken ship No. 2 on the northwest slope of the South China Sea during the Hongzhi period of the Ming Dynasty. The survey shows that the two sunken ships on the northwest slope of the South China Sea are of similar ages, with a distance of only over 10 nautical miles. This is the first discovery of ancient ships sailing and returning in the same sea area in China, fully proving the importance and prosperity of this route at that time. "The No.1 and No.2 sunken ships on the northwest slope of the South China Sea are relatively well preserved, with a large number of cultural relics and a clear era. They have very important historical, scientific and artistic values. They are not only important discoveries of deep-sea archaeology in China, but also world-class archaeological discoveries," said Yan Yalin, director of the Department of Archaeology of the National Cutural Heritage Administration. This important discovery has proved the historical facts of Chinese ancestors' development, utilization and exchanges in the South China Sea, and has made a breakthrough contribution to China's marine history, ceramic history, overseas trade history, and research on the Maritime Silk Road. Xinhua News Agency reported that this major discovery fully demonstrates the beautiful prospect of cross-border integration and mutual promotion between China's deep-sea technology and underwater archaeology, marking China's progress in deep-sea archaeology towards the world's advanced level. Many netizens commented, "There is a feeling of being in line with the past time and space
