Meaning:

    “黄昏” means “dusk,” and “恋” means “romantic relationship.” While in Chinese, people use the metaphor of rising sun for youth, the image of setting sun is associated with old age. Therefore, a romance involving two seniors is often called “黄昏恋,” which literally means “love at dusk.”

    Example:

    A: 马大爷最近心情不错，打扮的也比从前精神了。
