Lyrics: The sun is out, and it is very happy ... What is the name of this song?

"Surprised" is a Sichuan folk song, written by Mr. Jin Gu, a poet, playwright and musician. Simple in form, optimistic and cheerful, expressing the feelings of mountain people who love labor and mountain life. The melody of the song is free, and the range is only six degrees. In the song, a large number of lining words "Rolle" and "Lang Lang La Guang La" are used to simulate the sound of percussion instruments, which reveals the singer's happy and complacent mood, makes the song more vivid and has a strong artistic effect.
