It can also be understood as not looking at the surface of anything, being good at observing the essence of things and responding as soon as possible. When things change, you will not be at a loss. If we take measures, we won't be afraid of deer coming out of fog and whales coming out of big waves.
This sentence evolved from Chen Liang's ancient theory of "Drinking Li Xi" in Song Dynasty: "The Emperor treats people with courtesy, treats them with sincerity, talks and laughs, and expresses his own opinions." It means: If you can treat people with courtesy, show sincerity and laugh heartily, you will immediately hear these heartfelt words.

If it snows in the desert, I will come to you.
If whales in the Atlantic can talk, I will come to you.
If you open the door and hug me that day, I will come to you.
People say:
See deer in the deep forest,
Watching whales when the sea is blue,
See you when you wake up.
But I:
Fog rises deep in the forest,
When the sea is blue, it surges,
I woke up and continued at night.
No deer, no whale, no you.
However:
Deer pass through the fog,
Whales rise with the waves,
How do you know I didn't come if you don't look back?
