Please tell me the meaning of “ sings of spring.”<br/><br/> <br/><br/><span style="background-color:#00ff00;">Wherever you go, you'll find sings of spring.</span><br/><br/> <br/><br/>Does this expression mean real sound when it comes spring, for example songs of birds, or roar of bears?<br/><br/>Or does this mean the scene of spring, for example the temperature you don't feel cold outside any more, or smells of spring flowers and grasses?<br/><br/> <br/><br/>I want to know whether this phrase is metaphor or not.
