Which nationality's song is "Wading across the River"?

This is a Yunnan folk song from Midu County, Dali Bai Autonomous Prefecture. The lyrics are simple, natural and imaginative. The whole song is in feather mode, with five phrases, which is a bit slow. It depicts a far-reaching artistic conception full of poetry and painting, with a long stretch, relatively free rhythm, ups and downs, fresh and beautiful melody, with Yunnan local characteristics: under the silver moonlight, it is quiet all around, and only the river at the foot of the mountain makes a gurgling sound from time to time. A-mei, who is smart and beautiful, expresses her feelings when she sees the scenery and the full moon, and pours her deep affection for her brother into a beautiful melody. Soft songs and deep friendship, with the flow of the river, floated to the place where my brother was.

The lyrics are: hey ~ ~ ~

The moon is shining brightly.

Bright and Wang Wang

Think of my brother in the mountains.

Brother walks like the moon in the sky.

Stroll through the sky

Brother, brother, brother

The stream at the foot of the mountain is flowing

Qingyouyou

Hey ~ ~ ~

The moon shines on the half slope.
