The meaning of eternity is: time has no end, forever, lasting for a long time. Pronunciation is, from San Guo Kang's "Answering Difficulties and Keeping Healthy": "Take virtue as a teacher and be friends, play with the changes of Yin and Yang, and be happy forever."

Example:

1, we just want to give our children two permanent legacies: one is roots and the other is wings.

In the basic laws of all governments, permanence is self-evident, even if it is not explicitly stipulated.

That tall old pagoda tree and the old house covered with moss will be my eternal memory.
