The second couplet is about Yingying Yan, which the poet saw in his journey. Yingying is a singer in spring, and everyone is competing to fly to the sunny tree to sing; Yan, the messenger of spring, has begun to build nests with mud and is full of vitality. Using "jujube" to describe oriole reflects Bai Juyi's sincere love for these vibrant little lives. The word "struggle" makes people feel that spring is rare and precious. Using a word "peck" to describe the busy and excited appearance of the swallow seems to bring the swallow back to life. These two sentences deliberately describe the dynamics of Yingying Yanyan, thus making the whole poem full of vitality and vitality in spring.
The third part is about flowers and plants, focusing on the poet's feelings. The horse walked briskly on the shallow grass and looked at the flowers for a long time. His eyes were full of colorful flowers, which made people dizzying and puzzled. This pair of couplets and the first pair of couplets are the core of this poem, and they are also the crowning touch to describe the spring scenery in the white poem, especially the spring scenery in the West Lake. This is an emotional and energetic description of the scenery, which fully shows Bai Juyi's careful observation of the object of description and accurate grasp of its characteristics.
