We know that ancient people would interpret natural phenomena that they could not understand as ghosts or signs. At that time, the sky was red in ancient times, and it was red for nine consecutive days, which made people more sure that this was an instruction from heaven. At that time, the sacrifices of the Ming Dynasty thought that there must be something important in this astronomical phenomenon, and the court was very afraid. The emperor didn't understand what the red sky meant, so he kept going in a bad direction.
Fortunately, this strange phenomenon disappeared after nine days, and nothing was found, so it was sacrificed, because the emperor was a chosen son and successfully saved the day. Of course, it was nothing at all, but people made a mountain out of a molehill at that time. Now the phenomenon of flaming clouds is also very common. As the sun sets, the fiery red sun hits the clouds as if it were burning, and the sky turns red.
People in ancient times knew this, but they just didn't know it, so they wrote it down directly and compared it to the so-called omen of catastrophe. The natural phenomenon of this uprising is nothing to us now, but for the ancients, this kind of thing is very incredible, and it may even really cause turmoil because of it.
