What is the content of the poem "Welcome to Summer"

Summer came quietly,

The frog told the bird:

Your nest is hanging in the treetop,

Don't let the wind blow away.

Summer came quietly,

The swallow told his baby:

You must learn to fly by yourself,

There are countless treasures in the sky.

Summer came quietly,

Peony flowers tell grass:

You have no beautiful flowers,

The earth needs your green robe.

Summer came quietly,

Everything cheered and danced together,

Spring jingles and sings,

Thunder and lightning beat drums and trumpets in the sky,

When you are tired of walking,

Let the rain bathe you.
