Read the following lines from thoughts of hanoi

the night is deep and chill
as in early autumn. pitchblack,
it thickens after each lightening flash
i dream of hanoi
co-ngu road
ten years of separation
the way back sliced by a frontier of hatred
i want to bury the past
to burn the future
still i yearn
still i fear
those endless nights
waiting for dawn.
