The butterflies in the flowers are dancing, and the soft yinger in freedom is just singing happily. What do you mean by nostalgia? Sometimes it means something.

Lingering: nostalgia, reluctant to leave.

Cha-cha: Onomatopoeia, which describes the harmony and sweetness of birds' songs. When we say "Chen Wenjing" is a Tang dialect, that's what it means.

The colorful butterflies wandering on the flower branches, because of their love for flowers, mean the fragrance and freshness of flowers. The flowers are lovely, and the dancing of butterflies is also lovely, which inevitably makes people who walk "linger". But he may not stop, but move on, because the scenery is infinite and there are many beautiful scenery. "Always" is not an occasional sight. Using this word, the fun of spring is rendered. Just when it was pleasing to the eye, a string of beautiful songs by oriole happened to wake up the poet who was intoxicated with flowers. This is the artistic conception of the last sentence. The word "jiao" describes Yinger's soft voice.

"Freedom" is not only an objective portrayal of Jiao Ying's posture, but also conveys the author's psychological pleasure and relaxed feeling. The poem ends with Ying Ge's "Chen Wenjing", which is full of charm. This poem is about appreciating the scenery, which is common in the quatrains of the prosperous Tang Dynasty. However, it is rare to see such a poem with a very delicate description and unusually beautiful colors. For example, "Home is on the shore of peach blossom until the stream flows in front of the door" (Chang Jian's "Looking for Li Jiuzhuang in Three Days"), "Last night, the wind opened the peach blossom well, and the moon was high in the front hall of Weiyang" (Wang Changling's "Spring Palace Song"). These scenes all look beautiful. Du Fu added "thousands of flowers" after "flowers full of new roads", butterflies and songs. This kind of writing is unprecedented.

People in the prosperous Tang Dynasty paid great attention to the harmony of poetic tone. Their quatrains can often be strung together, so they are very harmonious. Du Fu's quatrains are not written for singing, but purely poetry, so there are often awkward sentences. In this way, the second word of the poem should be flat and used regularly. However, this contradiction is by no means an arbitrary destruction of the melody, and the overlapping of thousands of flowers has a beautiful taste. Although thousands of flowers and the four words in the same position in the previous sentence belong to the same sound, the rising tone and falling tone are different from each other, and the tone still changes. It's not that poets don't pay attention to the musical beauty of poetry. This is manifested in the use of disyllabic words, onomatopoeic words and reduplicated words in three or four sentences. Linglian and Freedom are disyllabic words, such as Guan and Wan Yi. It's just an onomatopoeic word, which describes the voice of a charming baby and gives people an immersive auditory image. Sometimes, just overlapping words make the upper and lower sentences antithetical, and make the meaning stronger and more vivid, which can better express the poet's sudden joy when he is infatuated with Hua Hudie and suddenly awakened by the sound of warblers. Except for the words dance and warbler, these two sentences are all tongue-toothed sounds. The use of this series of tongue-and-teeth sounds creates a sense of language, which vividly shows the feeling that flower lovers are intoxicated and surprised by the beautiful scenery. The utility of sound is very helpful to the expression of emotions.
