On August 26, 2023, in Guangdong, a puzzling spectacle was captured as a large number of fish jumped out of the water and tried to swim away in the same direction.

The video from an overhead view shows a vast expanse of water filled with surfacing fish, which collectively swim in one direction to the east, presenting a spectacular image that would provoke intensive phobia.

According to the filmer, the shoal of fish swam at least a kilometre in twenty minutes or so. Locals on a nearby bridge also claimed to have never seen such a sight.

This bizarre incident occurred three days after the release of nuclear water, causing some panic among residents.

As to media reports, such behaviour of fish may be due to lack of oxygen or food, but the exact cause is still under investigation.
