Li Bai's poem "Listen to the Flute in Luo City on a Spring Night" uses rhetorical techniques of metonymy and pun. The "breaking willow" in the poem is caused by hearing the flute sound of the song "breaking willow". The feeling of homesickness: "The sound of someone's jade flute is flying quietly, spreading into the spring breeze all over Luo City. I hear the broken willows in this nocturne, who can't help but feel the love of hometown." This poem was written by the predecessors in the "Net Master's Garden Tang Poetry Notes" His evaluation is: "The word 'Zheliu' is the key to the first chapter." "Zheliu" originally means "breaking willow branches." According to legend, there is a bridge in the east of Chang'an named Baqiao, where Han people would break willows to say farewell or farewell to guests. In Li's poem, "I hear the willows breaking in this nocturne" is the provincial title of a song called "The Willows Breaking". This song is often used to express farewell and long-distance feelings. This poem describes: When people were quiet in the spring evening, the poet suddenly heard a melodious flute sound, and listened to it. The flute sound was the song of "Breaking Willows". The author can't help but be moved by the scene and stir up thoughts. It is the season of breaking willows. Spring has arrived, but he is drifting away, which makes him feel homesick.

The theme of "Preface to the Cry of Orioles" is mourning.

Yichuan tobacco, the city is full of wind and rain, and plums are yellow and rainy. "("The Sapphire Case"); Li Qingzhao's "I am afraid that the grasshopper boat in Shuangxi will not be able to carry it, and there will be many sorrows. "Wulingchun" are all famous words and phrases describing melancholy, and they all use the form of visual thinking to write the melancholy vividly and deeply shock the readers' hearts. Li Yu, the later master of the Southern Tang Dynasty, wrote Dongliu's poem The spring water of a river is a metaphor for the turbulence and prosperity of his own melancholy after the subjugation of the country, and vividly expresses the misery of his life as a prisoner; while He Zhu used three images of "a river of tobacco, the wind in the city, and the yellow plums in the rain" to represent the overwhelming and waving emotions of melancholy. Li Qingzhao used the delicate writing style unique to female poets to express the depth of sadness after the collapse of the country and the unbearable pressure he felt.
