How did the ancients describe the sky and the sea?

Some old friends will use poetry to describe the sky and the sea. For example, "the sea is wide and the fish jumps, and the sky is high and birds fly."

The sea is wide and the fish jumps, and the sky is high and birds fly. The vastness of nature provides a vast space for fish to jump and birds to fly, which means that people can freely display their talents in a vast world.

Song Ruan read Poems before the Turtle (Volume 30), quoting ancient and modern poems, saying: During the calendar year of the Tang Dynasty, Yuan Lan, a monk, wrote poems with bamboo: "The sea jumps from the fish and birds fly in the sky." This poem expresses the free and broad mind and lively Zen machine of Zen monks. Later, it was changed to "the sea is wide and the fish jumps, and the sky is high and birds fly", which means that you can move freely or display your talents freely.
