The lyrics "I sing with the grassland" are from the square dance song of the same name "I sing with the grassland". I've uploaded this song to share with you.

Lyrics:
The blue blue sky, white clouds
The mercurial breeze, the face of the brush
The bosom of the grassland, like the infinite expanse of the grassland
I have climbed up to the hillside, wanting to play the sound of a song. I climbed up the hill and wanted to sing
The green pastures, the colorful flowers
I drank the wine and rode on horseback
The love song in my heart became more and more spontaneous
The drunken heart burned with bonfires
Me and the grassland, we sang together
Singing of the beautiful life in my dream
Singing of the clouds that don't need to drift anymore
Singing of Abba's father, who is a good man, and of the clouds that don't need to wander.
