What does it mean when the sky is red when you are born?

It means that the sky is full of red light when you are born. This is a fantasy and unreal phenomenon, and it can also be understood as an abstract description by literati.

When I was born, the sky was red. I wrote down eighteen lines of poetry. When I was alive, the sky was red. No, this is not a poem at all, it seems like a mantra. This is like a Feng Shui phenomenon, a superstitious statement with no scientific basis.
