The first line is the blue sky, seems to be Zhou Siping Square Dance, I do not know which song on the grassland lyrics inside the song

The Grassland Battle Hymn

Naren Hua leads the song

The blue sky

The red sun

The snow-white sheep

The turquoise pastures

The vast grassland is red and full of color

The motherland's border is as strong as steel

Heroic sons and daughters have produced and fought here

Mao Tse-tung Thought has armed us with the best of all possible worlds

Mao Tse-tung Thought has armed us with the best of all possible worlds. Armed

The vast grasslands are red

The motherland's borders are as strong as steel

Heroic sons and daughters are here to produce and fight

Mao Tse-tung's thought has armed us

Battling in the motherland's outposts

Defending the sacred frontier

Thousands of kilometers of grassland are set up as a battleground

Swords and spears are seen in the windy grasses

The sheepherders watch out for man-eaters

The sheepherders watch out for the man-eaters. The sheep herders are on guard against the man-eating wolves

The lasso poles are waiting for the vicious wolves

Everyone is a brave sentry

Everywhere there are vigilant eyes

National unity is like an iron wall

Military-civilian alliance seems to be like a brass wall

Wielding the saber to cut off the claws of the aggressors

Lifting up the shotguns to bury the enemies once and for all

There is no doubt that the enemy has been killed in the battlefield.
