What does spring silkworm mean in your poem?

Spring silkworm is a kind of creature, which is raised in spring. In poetry and literature, silkworm is used to describe teachers and other people who are willing to give.

What does it mean that silkworms will weave until they die in spring?

The opportunity to meet each other is really hard to get, and it is even more difficult to part when we break up. Moreover, the weather in late spring, the east wind is about to close, is even more sad. Spring silkworms don't spin silk when they die, and wax oil like tears can drip dry when candles are burned to ashes. Women dress up in front of the mirror in the morning, only worrying that the plump bangs will change color and the youthful appearance will disappear. Men can't sleep at night, so they must feel Leng Yue's aggression. The other party's residence is not far from Penglai Mountain, but there is no road to cross, but it is out of reach. I hope a messenger like a bluebird will visit my lover diligently for me.

This poem was written by the poet Li Shangyin when he was fifteen or sixteen years old, and was sent to Yuyangshan by his family to learn Taoism. In the meantime, he met and fell in love with Song Huayang, a female Taoist priest in Yuyang Mountain, but their feelings could not be known to outsiders, and there was an irresistible wave of love in the author's heart, so he could only remember his feelings with poems and hide the topic, thus making his poems both vague, graceful and affectionate.
