The application of artistic techniques in poetry can be divided into the following three forms: expression, rhetoric and expression.
In terms of expression, the first couplet mainly uses description. The poet closely followed the seasonal characteristics of autumn and described the empty and lonely scenery along the river. Focusing on the specific environment of Kuizhou, the poet used the word "Fengchong" to drive the All-China Federation. Kuizhou is famous for its many apes, and the canyon is famous for its windy weather. It is cool in autumn, but it is windy here. When the poet climbed the mountain, the sound of "high apes whistling" came from the gorge, which means "the empty valley spread and the sorrow turned into the sky". The poet moved his eyes from the heights to the rivers and lakes, and on the background of clear water and white sand, he was dotted with birds dancing with the wind and never looking back. This is really a beautiful painting. The first couplet focuses on describing the specific scenery in front of us, just like the meticulous brushwork of a painter, showing the shape, sound, color and state one by one.
Rhetorically, the first couplet mainly uses duality. The first couplet matches, and the sky, wind, sand, bamboo, apes whistling and birds flying, which are made in heaven, are naturally paired. Not only the upper and lower sentences are correct, but also the sentences are self-correct, such as the above sentence "day" to "wind" and "height" to "urgency"; The next sentences "sand" versus "Zhu" and "white" versus "green" are full of rhythm.
In terms of expression techniques, it mainly uses the artistic techniques of combining static and dynamic, visual and auditory. "the wind is urgent" is moving, and "the sky is high" is static; "Apes wail" is hearing, "Birds fly back" is vision, and "Zhu Qingshabai" is vision in still scenes. The combination of dynamic and static, audio-visual combination, gives readers different touches.
