This reaction can be seen in a slightly famous poem.

When you can't see everything, you can see leopards, see what you can see, see the sky through a hole and see the sky from the bottom of the well.

When it means "from the observed part to the whole":

Words:

See the big from the small, and see the big from the small.

Poetry:

A leaf falls, you know the autumn of the world.

A world in a sand, a leaf in Kun.

Su Shi's poem "I brought this stone home with the East China Sea in my sleeve"

The poem in Du Fu's Qujiang is "A flower flies away, but it turns into spring"
