The emphasis is on landscape and narrative. The pen is unique at the beginning, and the festival is hidden in the scenery. Huayang is flying all over the sky, erratic; Zi Gui (cuckoo) cried "It's better to go home" and her voice was piercing. The description of the scenery highlights and sets off the specific festivals and environments in late spring, and also symbolizes the feeling of loneliness and the pain of parting. It's really perfect! It plays a role in determining the emotional tone of the whole poem.
