Cicada is a noble person. The ancients believed that cicadas eating in the wind and drinking dew were a symbol of nobility, so the ancients often used the nobility of cicadas to express their nobility of character. "Tang Shi Bie Cai" said: "Every time a cicada chanter sings its voice, this is the only way to respect its character."
Because cicadas live on high branches, eat the wind and sleep in the open air, and do not eat the fireworks of the world, it is a metaphor for His character is of the noble type. Luo Binwang's "Cicada in Prison": "No one believes in nobleness." Li Shangyin's "Cicada": "It's hard to be full because of high status", "I also want to clean up my family." Wang Yisun's "Qitian Le": "To hold one's nobility alone suddenly becomes sad." Yu Shinan's "Cicada": "It is not to borrow the autumn wind to speak loudly and far away." They all use cicadas to refer to noble character.
