I want to know why my Jinse has fifty strings, and each string has a youthful interval.
Zhuangzi daydreaming, a saint, was bewitched by butterflies, and cuckoo crowed in the imperial spring.
Mermaids shed pearl-like tears on the moon-green sea, and the blue fields breathed their jade to the sun.
A moment that should last forever has come and gone before I know it.
This is a love poem, and the couplet uses two allusions. One is that Zhuang Shengmeng Butterfly said that Zhuangzi dreamed that he had become a butterfly. After waking up, he still didn't understand whether the butterfly had become himself. He was lost in it and couldn't find a perfect answer. The second argument is that the crow cuckoo said that Du Yu, the monarch, became a cuckoo after the death of Shu. Because he could not bear to leave his people, when spring came, he always crowed until he bled, so another cuckoo cried. This sentence actually refers to the author's deep and infinite yearning for a certain emotion in the past, and his obsession with it will never be resolved.
