Blood-red sky omen

There is nothing ominous about the red aurora.

Teach yourself why this blood-red sky is frightening, because from ancient times to the present, there are always some rare signs before a catastrophe occurs in a certain place, but people always know it later and don't take it seriously, because it can't be explained by science after all. For example, before the earthquake, there were all kinds of abnormal omens, such as abnormal sky clouds, abnormal groundwater and abnormal weather. These are the so-called "disaster omens".

There are three conditions for the emergence of "red night sky":

One is to have a red light for ocean-going fishing boats. The stronger the red light, the better the effect.

Second, the rainy weather environment, a lot of water mist floating in the air, high humidity.

The third is to watch from a certain height and angle.
