Tu Fu - Overnight at the Riverside Tower

Evening colors linger on mountain paths.
Out beyond this study perched over River Gate,
At the cliff's edge, frail clouds stay
All night. Among waves, a lone, shuddering

Moon. As cranes trail off in flight, silent,
Wolves snarl over their kill. I brood on
Our wars, sleepless here and, to right
A relentless Heaven and Earth, powerless.

Tu Fu
