As an old Indian proverb says, the hand that sends roses is still fragrant.
In English, it means "the rose in her hand, the smell in my hand."
"Give someone a rose, there is fragrance in your hand" is also an English proverb, which means a very common and trivial thing, even if it is as trivial as giving someone a rose, it will bring warmth to both the giver and the recipient. In life, we should all do this.
