You are talking about the poem "Spring is So Lively", right? These three catches are different. Although they all have the general meaning of acquisition, their starting points from a sensory perspective are quite different. The first "catching" means observing and hearing; the first "catching" means using the eyes to discover and appreciate the beauty of spring; the second means using the ears to listen to the beauty of spring; and the third means using the heart To feel the love of spring. And the third one is to feel it. So you have to speculate a little more.
