What profound meaning did Yu Shinan express with the image of cicada?

In the poem, the author compares the cicada to himself and writes that he lives like a cicada, lives high, has high moral character and enjoys a natural reputation. He uses cicadas to write his noble personality, and his reputation enjoys a high reputation, rather than relying on external forces.

Author: Yu Shinan

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.

Translation:

On the bleak phoenix tree, cicadas drink low and clear dew, and the cicada sound is crisp and loud, echoing among the trees.

Living on high branches, the swarm can be proud. Without the help of autumn wind, the sound is still far away.

The third sentence and the fourth sentence use the words "self" and "non" respectively, which are full of tension in both positive and negative aspects, expressing warm praise and high confidence in people's inner character. The whole poem is concise and vivid, and the metaphor is clever, which is thought-provoking with Qiu Chan's noble and arrogant character.
