In appreciating Yu Fang's works, what rhetorical devices did the author use to express his feelings?

This seven-character poem was written by Wang You for his study, expressing his feelings when he lived in seclusion. In the poem "From the Lake to the Palm Mountain Residence" by Wang Chang in the Qing Dynasty, he said: "In order to make up for the principal of the Ministry of Punishment, Gu Yuan (Wang Youzeng) was ill and took a leave of absence. He likes drinking, talking and laughing, and he looks chic. Although he is wandering in the Jianghu, there are many long-term officials in the southeast. I have been writing poems and fighting for wine for more than ten years, but I died. " Based on the aversion to etiquette, yearning for Jianghu life and nostalgia for Jiangnan's hometown, it is speculated that poetry is a true portrayal of the poet's thoughts and feelings at that time, regarded as the aftermath of the Ministry of Punishment and a plea for illness.

The first pair of couplets grasped the problem and wrote the mood of reading. Poets occasionally read by the water, stretch their lofty hearts, put down their work and fly freely between heaven and earth like Europe. The sentence "leisure" is obviously expressing "flying around, flying around, what am I, but a sandpiper in the vast world!" In Du Fu's poem One Night in a Foreign Country. Couplets set off emotions with scenery. Residual rain blows all day long, and waves of cold air attack people; A Qiu Chen Gao sat on a buttonwood tree and whispered something, which sounded a little sad. The word "cold" has two strokes, which not only describes the weather, but also expresses people's emotions. "White" and "blue" are cold and harmonious with the poet's mood. Neck joints look at mentality from temperament. The wild temperament and lazy modality express the poet's admiration for the free life in the Jianghu and his resistance to feudal etiquette. It is the environment that makes Zhuan Xu take advantage of the situation to reveal a sad mood. Necklace expresses its anger from two aspects: scene and emotion, which is the expression of the poet's true nature. "Madness" comes from inner irrepressible fortitude and blood, and "laziness" comes from contempt and confrontation with etiquette. "Flying" is a kind of ideological fluctuation that is difficult to turn over. Unfamiliar spreads the spiritual course from observing etiquette to ignoring etiquette. The tail is attached to the dream to send homesickness. Wang Song Anshi's poem "Western Pacific Palace Wall" says: "The willow leaves are black, and the lotus flowers are red at sunset. Thirty-six streams of water, Baishi wants to see Jiangnan. " There are thirty-six vicious cycles in Bianjing and Tianchang County (now Anhui) in Yangzhou. Wang Anshi revisited the thirty-six vicious circle of Bianjing and remembered that he had visited the thirty-six vicious circle of Jiangnan, which was full of spring water (in fact, Tianchang County is in Jiangbei, which is simply close to Jiangnan). The poet leaned on his pillow to watch the red lotus in autumn water and gradually fell asleep. In his dream, he saw the deep thirty-six vicious waters of his hometown in the south of the Yangtze River that he missed day and night.
