Bohai Bay, an inland sea in China, is bordered by Liaoning, Hebei, Shandong, and Tianjin. It is said that Bohai was once a flat expanse of land before it transformed into the sea we see today. Recent analysis of satellite images of Bohai Bay has revealed a striking square formation, capturing significant attention.

This formation measures approximately 24 kilometers in length from north to south and about 20 kilometers in width from east to west, located roughly 79 kilometers northwest of Dalian. The alignment of the formation's vertical edges with the meridian and its base parallel to the latitude lines suggest a layout reminiscent of ancient city structures. Scientists speculate that this could be the remnants of a submerged ancient city, although it may also be a natural occurrence.

During their research, scientists discovered that several shallow water zones correspond with the three vertical edges of the formation. Furthermore, the last marine transgression in this area occurred around six to seven thousand years ago, well before humans could have constructed such a massive project. The region is also seismically active, with strong tectonic movements, raising the possibility that remnants of ancient human activity might have been submerged by rising sea levels due to tectonic subsidence.

While no conclusions have been reached yet, this discovery undoubtedly holds significant implications for understanding the formation of Bohai Bay, the evolution of ancient geography, and the development of Chinese social history. Research into this mysterious formation continues.
