花枯花瓣追
[huā kū huā bàn zhuī]
Literally means 'chasing wilted flower petals'. It vividly paints a picture where withered flowers and petals flutter down, being trailed. Metaphorically, it expresses the sadness about fading away beauty and lost loves. One may feel melancholic when reflecting upon bygone good days or lost love and youth through such scene.
