Cicadas symbolized holiness, innocence and nobility in ancient times. Before the cicada finally shelled and became an adult, it always lived in muddy water. When it shelled and turned into a cicada, it flew to the tall tree and drank only dew and sap, because the cicada was compared to a noble character.
Cicadas can live in the earth and emerge. People use the emergence of cicadas as a metaphor for people’s rebirth. If the jade cicada is placed in the mouth of the dead, it will embody the immortality of spirit and regeneration and resurrection. And wearing cicadas on the body means noble and clean. Therefore, jade cicada is not only the ornament of strangers, but also the burial jade of the dead.
