China's new manned submersible Shenhai Yongshi, meaning “deep-sea warrior”, returned after completing all deep-sea testing in the South China Sea.

It reached a depth of 4,500 meters to test functions and performance during an over 50-day expedition. This means China has become a nation with the ability to produce and test its own massive deep-sea submersibles.
