Is it a normal natural phenomenon that there is an unknown "light beam" in the night sky of Jeju Island in South Korea?

Personally, I think this is a very normal natural phenomenon, because this phenomenon is formed by the reflection of the sea surface into the sky, which can be regarded as a kind of uncanny workmanship of nature.

how can I say, there are some in the night sky? Light beam? The phenomenon is normal. If you live by the sea, this phenomenon can be seen everywhere at night (most of the time, it is not every day, but it is more common in autumn and winter), but I don't know if it is a natural phenomenon. Because this phenomenon is mainly caused by fishermen going out to sea to fish in the middle of the night, fishermen will turn on the lure lamp when they go out to sea to fish in the middle of the night, because many fish are phototactic and will swim when they see the light source. Sometimes the thickness of clouds in the sky is relatively uniform, and there is no light pollution, so the massive fishing lights on the massive fishing boats will be put into the air under the mapping of seawater. You can understand that the lure lamp of a fishing boat is a light source, while the sea surface is a mirror and the sky is a curtain. Just like when we show a movie, we put the light source on the curtain through the mirror, and finally this appears? Light beam? Phenomenon.

there is a saying that the night sky appears? Light beam? It's nothing to be curious about. This phenomenon is often built by the sea. In fact, you can't doubt that you have studied nine-year compulsory education. Of course, people in the inland definitely don't know it, but people who often live by the sea know it. For example, Jeju Island in South Korea is a city near the sea, and there are many fishing boats. Many fishermen will go fishing in the middle of the night, and fishing lights must be turned on in the middle of the night, which leads to this phenomenon. This phenomenon can be simulated. All you need is a high-power flashlight and a curtain. In the middle of the night, turn off the waiting room, then face the mirror with a flashlight, and then put the curtain in front of the bright spot of the light source in the mirror. You can see that there are bright spots on the curtain. Some people here will ask, why not a light beam? Quite simply, the curtain has poor light transmittance, unlike the clouds in the sky, where layers of clouds are stacked together.

Generally speaking, this can be regarded as a normal natural phenomenon, because it is the lure lamp on the fishing boat that reflects into the air on the sea surface.
