Whose job is drinking dew?

Ancient poems:

cicada

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.

Poet:

Yu Shinan (558-638), Bo Shi, was a calligrapher, writer and poet from the Southern and Northern Dynasties to the Sui and Tang Dynasties. Yu Shinan is good at calligraphy, and he is also known as "the four masters in the early Tang Dynasty" with Ou Yangxun, Chu Suiliang and Xue Ji. Representative poems include "Out of the fortress", "Songs of Complaint" and "Fu Ying Zhi".

Translation:

On the bleak plane tree, cicadas bowed their heads and drank dew, and the ringing cicadas echoed in the forest. Cicada is on a high branch, so its voice travels far, not because of the power of autumn wind.
