I want to know when the running train on the trail
Does the tracks feel so tired
I want to know when the dying rose
If the stamen feel so shame
The leaves leave the tree
The summer fade in winter
The mountains cover by the sea
我们也终将别离
I want to know when the plane at night
Why they blink like twinkle eyes
I want to know why the big world
Why I still can't figure it out
The leaves leave the tree
The summer fade in winter
The mountains cover by the sea
The summer fade in winter
The mountains cover by the sea
我们也终将别离
