Passion dries up, love slowly dries up?

In ancient China, there were many poems about passion and the exhaustion of love. Here are some examples:

1. "Blood has dried up and feelings are fading." -Li Sao

2. "Passion is like fire, but now it's gone, and love is like water, which is gradually drying up." -Eternal songs of sadness

3. "Enthusiasm is like a candle. When it burns out, only ashes remain. " -"Mulan Poetry"

4. "Enthusiasm is like a spring flower, which blooms for a while and then withers. Love is like autumn leaves, falling silently. " -"White-headed Song"

5. "Passion is like fire. It burns for a while and now it turns to ashes. Love, like water, has been flowing for a long time and now it is dry. " -"operator"

6. "Enthusiasm is like a tide, and only mud remains after it recedes. Love is like a smoke cloud, and after it disappears, only emptiness remains. " -Partridge Day

7. "Enthusiasm is like fire, which leaves only ashes after burning. Love is like running water. When it is exhausted, only emptiness remains. " -"Langtaosha Northland Scenery"

These poems express the exhaustion of enthusiasm and love, and the resulting sense of loss and emptiness.
