could he actually have written it?
maybe. maybe not.
but first let me venture to translate it into English:
The evening sun is setting among mountains yonder
On east-west highway my spirit aimlessly wanders
The winds are slowly rising
And the geese are gracefully landing
How much do you think you really know
What it's like to be a wandering soul?
the poem did appear in a newspaper soon after the poet's tragic death in a plane crash.
possibilities:
1 someone wrote the poem in his name and style
2 the poet was afraid of flying and wrote the poem in case something happened
3 his ghost came back and wrote it
