When was the song "Children of the Grassland"?

Lyrics of "Children of the Grassland"

Sunshine ah sunshine how bright,

Spring ah spring came to the grassland,

White clouds drifted away above my head,

Sheep scattering around me.

Ah ah ah ho ee ah ah ah ah ho ee ah ah ah ah ho ee,

White clouds, white clouds, ah go slowly,

I sing the pastoral song, ah please pass it on,

The children of the grassland love the commune,

Chairman Mao's teachings to remember in the heart.

Our hometown is so rich,

The green waves of the vast grassland are boundless,

Sheep whip and shovel in hand,

The heavy burden of the revolution on the shoulder.

Ah ah ah ho ee ah ah ah ah ho ee ah ah ah ah ho ee,

Sheep, sheep, sheep, sheep, sheep, ah quickly return to the line,

Listen to my command ah again forward,

The prairie children learn from the Thunderbolt,

Determined to take over the revolutionary class.

The ballet "Children of the Grassland" was made into a stage art film, in which the daughter's dance of milking the cow under the guidance of her mother is a classic. Admirable netizens, to the original dance with a concert performance suite based on the original ballet music adapted in recent years, the tonality is different from the original.
