A modern poem in the Chinese language book of the first grade of elementary school in 1981 begins with seagulls flying, blue water, and waves running on the beach. What is behind it?

Seagulls fly, the sea water is blue,

The waves run on the beach.

The sea, the sea, I ask you:

How deep and wide are you?

How many fish are hidden in your arms?

How many The waves keep turning,

How many treasures are buried under the sea,

How many years have they been sleeping?

You are waiting for the big ocean.

I will do experiments when I grow up.

Let the fish and shrimp obey orders,

Let the waves generate electricity,

Let the seabed be filled with treasures,

Let the beach Turn into fertile farmland.

Seagulls fly, the sea water is blue,

The waves nod their heads happily.
