Leave the shadow behind, which poem is it from?

Are you looking for the ending poem of the old movie "Backlight" shot in 1982? The whole poem is as follows:

Friend, friend

Please don’t be sad

You say life is like a desert

It’s because of your heart There is no oasis

Dream a green dream first

Only then will there be a golden autumn

Friend, friend

Please give me a thousand Don’t be sad

You said there are shadows on the ground

It’s because you always lower your head

Stand up your chest

Facing the sun Go

Leave the shadow of darkness behind forever
