The first two sentences are about the unfortunate experience of love and the mood of the lyric hero: because of some power, it is difficult for a pair of lovers to meet each other, and the pain of separation is unbearable for her.
This lyric hero is already so sad, but facing the scenery in late spring, of course, it makes her sad. In late spring, the east wind is weak, flowers bloom and fall, and the beautiful spring is about to pass away. There is nothing that human beings can do about it. Their own misfortunes and mental pains are like flowers that wither with the passage of spring, because beautiful things are destroyed, which makes people feel endless disappointment and regret!
"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. However, although the future is hopeless, she loves it to death and will be attached to it all her life; Despite the pain, there is only patience.
This poem is full of pain, disappointment, lingering and persistent feelings from beginning to end.
