What is the name of the accompaniment of the poem "I hear a bird singing" in Unit 12 of the second day of the People's Education Edition? Which angel can help me find it?

I've been thinking about this song for many years. . . I can't find the name, but I can hear the following notes:

*

1 76 5-/ 32 567 1 0/ 1 1 23 5/ 5 666 165/3 2 3 55 3 1

* * * * *

3 23 5 2/ 22 1 7 1/ 1 1 1 1235

*

Looking forward to the angel's answer ...

PS: I hope I can comfort you with another song first.
