From the emotional analysis of poetry, the silkworm will weave until it dies in spring, and the candle will drain the wick every night.

Spring silkworms will not stop spinning until they die, and their tears will dry when the wax torch turns to ashes.

Of men and women: our feelings will never change. It's like a spring silkworm spitting all its silk before it dies, and it's like a burning candle burning itself to ashes before it dries its tears.

Of a career: devote yourself to a career, such as a silkworm wax torch, until you die without regret. Teachers and parents treat children.

Refers to determination: a firm belief, like a silkworm and a wax torch, will persist until death.
