Appreciation: The word "silk" in "Spring Silkworm Woven to Death" is homophonic with "thinking". You miss each other like silkworms until you die. "And the candle will cry the wick every night" is a metaphor for the endless pain of not being together, as if the candle burned to ashes and the wax tears ran out. Miss more than, showing deep attachment, but will spend a lifetime in miss, but it also shows that meeting is indefinite and the future is hopeless. Therefore, his own pain will accompany him all his life. The poet successfully expressed such a complicated psychological state with only two metaphors, which shows that his association is very rich. The phrase "Spring Silkworm" is first of all the association between the lingering attachment of human beings and the endless spinning of spring silkworms, and then from the spinning of silkworms to the ending of "death" and then to the unswerving love of human beings. So writing "silk to death" gives this image various metaphorical meanings.
