Lyrics: Wang Lu, Wang Yunjie

Original song: Wang

Swallows wear gorgeous clothes and come here every spring.

I asked the swallow, why did you come? The swallow said, "Spring is the most beautiful here!" " "

Swallow, I tell you, it is more beautiful here this year.

We built a big factory and installed new machines.

Welcome to live here for a long time.

Swallows wear gorgeous clothes and come here every spring.

Swallow, I tell you, it is more beautiful here this year.

We built a big factory and installed new machines. Welcome to live here for a long time.

Precautions:

In a film about socialist construction, such a children's song suddenly appeared, and its influence even far exceeded the film itself, which was an unexpected thing. I'm afraid the creator of this film chose this song as an episode, not just to coax children.
