cicada

Yu Shinan [Tang Dynasty]

Cicada droops like a tassel on a hat, its tentacles suck the clear dew, and its voice spreads from the branches of the straight Shulang tree.

Cicada is far away from cicada because cicada is on a tall tree, not relying on autumn wind.

translate

Cicada hangs down its tentacles like a hat tassel, sucking the clear and sweet dew, and constantly chirping from the sparse branches of the phoenix tree.

Cicada's voice can spread far because of its height, not by the power of autumn wind.
