What do you mean, love is deep and shallow, and there are many bumps?

Although the feelings between two people are deep, for various reasons, the fate between them is very shallow and it is difficult to be together. In this relationship, we often encounter problems and difficulties, most of which are stumbling.

This sentence expresses a kind of helplessness and regret for feelings, and also reminds people to cherish their immediate feelings and not to give up easily.
