Butterflies have been dancing, and charming warblers are just crying. What does this mean?

. "Chen Wenjing Jump" refers to the poet Shang Huashi enjoying the beautiful scenery, and a string of wonderful orioles happened to wake up the poet who was intoxicated with the flowers. Just because the poet was happy, he took it for granted that oriole was singing for himself. This is the same as the previous sentence, saying that butterflies are attached to spring flowers, which is empathy. Because the poet successfully used this technique, things and I blended and the scene came into being. This kind of theme is common in quatrains in the prosperous Tang Dynasty. However, it is rare to see such a poem with exquisite description and unusually beautiful colors. After Du Fu's "Flowers Like Flowers", he added "Thousands of Flowers" and butterfly singing and dancing, and the scenery was beautiful. This kind of writing is unprecedented.
