What's the nursery rhyme about the nice weather today?

The lyrics of "It's a beautiful day today, balloons are floating in the sky" come from the children's song "Go to kindergarten happily":

It's a beautiful day today. Balloons float in the air.

Birds come to watch the fun, and the sun smiles slightly.

There are many toys, like flowers, which make people happy.

Healthy and energetic, just like iron king kong.

Mom and dad are here, praising my good baby.

Singing and dancing, everyone croaked.
