Lyrics of Huang Guanzhong's I understand I don't understand

I can't see the white and black outside the window

The sky is always so grey

I can't tell who yesterday was for

All over the world

I'm sad, but I can't shed tears

Will this guitar break down when I'm drunk

I can't hear right and wrong outside the door

It's like the tide of a sea of people

I can't tell if I'm still tired

Like a strong fortress

I'm on guard, but I can't fight you

I am ambiguous. Is this expression a demonstration

I understand. I understand. I don't understand

I understand. I don't understand

I can't see the white and black outside the window

The sky is always so grey

I can't tell who yesterday was for

All over the world

I understand. I understand. I don't understand

I understand. I don't understand

I understand. I understand. I don't understand

I understand. I don't understand

I can't see the white and black outside the window

I can't hear right and wrong outside the door
