On reading Lu Chi's "The Art of Writing"

Now that the stalks
have been brought from the fields
Now that the chaff
has been stripped from the grain
Now that the grain
has been ground on the mill
The bread has been baked
and the meal has been eaten
Now that stomachs are full
and eyes shut in sleep on the
sated faces of my contented family
I'll return to my fields
plant new seeds

What's the use after all
in leaning on my plow?
