Did ancient poets write poems about going to the toilet?

There are no birds in the mountains,

A thousand roads without footprints.

Oriental root-seekers,

Piss, nun.

The moon shines in the afterlife,

Look at the pants hanging half-crotch.

Flying down from 3,000 feet,

It's been nine days since I suspected that the Milky Way had set. Ticillin is better than Su Xipo.
