What does it mean that love is like the wind blowing away?

This sentence is a figurative description, which means that love is like a plate of fine sand, which is easily blown away by the wind, indicating the instability and fragility of love. It implies the variability and instability of love, which may sometimes be terminated or lost due to external factors or internal changes.

This metaphor may come from the scene of sandstorm. The sand in the sandstorm is blown by the wind and scattered in the air, just like contradictions, quarrels, distances and other elements in love, which may make the original intimate love relationship alienated and fragile. So the meaning of this sentence is to remind people to cherish and maintain their love, realize the fragility of love, and strive to maintain a stable and solid emotional relationship.
