The first of two late-night ballads

[Author] Cao Xun (Song)

Bloom is warm in spring, and things have changed.

Grass invades the road and dust fills the old smoked clothes.

Independent and empty, I cherish the shadow, but I fold my eyebrows when I sing.

I haven't seen the door for a long time, and I have returned home synchronously.
