1. Voltaire: The noble element in love is as much as the gentle element, the upward force is as much as the debilitating force, and sometimes it can inspire other virtues.

2. Gurnell: Although the joy of love is extremely sweet, it can only survive where glory and virtue exist.

3. Dante: Love sublimates the human heart's longing to the state of perfection.

4. Gorky: Without the sun, flowers will not bloom; without love, there will be no happiness; without women, there will be no love; without mothers, there will be neither poets nor heroes.

5. He Qifang: Love is like a leaf, it turns green in people's neglect, and its buds emerge in patience.
