Let's paddle. What does this song describe and praise?

The song "Let's paddle"

Lyrics:

Let's paddle

The boat pushes the waves

The beautiful white tower is reflected on the sea

The boat is surrounded by green trees and red walls

It floats gently in the water

There is a cool wind

The red scarf welcomes it.

There is a cool wind blowing in the water

After a day's homework

Let's have fun

I asked your dear partner

Who will arrange a happy life for us

The boat floated gently in the water

There was a cool wind blowing in the face

It described the scene of a group of young pioneers boating in Beijing Beihai Park after school. Praise the happy life of children after the founding of New China. Expressed gratitude to the party and the government.
