The style of the sentence "There is scenery in the peak night, and the deep valley is unclear in the daytime" is still "strange danger". In the same place, "night" and "scenery" (sunshine) are incompatible with each other; The author insists on arranging them together, which can not help but give people a feeling of "strangeness". However, if we carefully ponder poetry, "staying at the peak night" just means that after other places are covered by night, the peak in the south still has the afterglow of the sunset. Extremely high, but not against the truth. Ever since The Book of Songs, Elegant Takamatsu, Takamatsu Yue Wei and the Third Runner-up Tian Yu, people have been used to expressing lofty peaks with expressions such as "inserting the sky" and "expressing clouds". However, Meng Jiao was born under the condition of avoiding familiarity. He grasped the characteristic scenery and exaggerated it. He found a new way out from "strict words make him soar", which is very novel. In the same place, "day" and "unknown" (night) cannot coexist. The author insists on unifying them, which naturally gives people the feeling of "danger". However, the original intention of playing with it is that "the deep valley is not sunny during the day" just means that when the sun is full in other places, the deep valley in the south is still dark. It's profound and realistic. The style of "danger" is also reflected in the exaggerated comparison between the upper and lower sentences. On the same Mount Zhongnan, its peak is as high as "overnight" and its valley is as deep as "the sky is not clear". One height and one depth, if the disparity is this, it will be "exaggerated". However, this is only through a height and a depth to show the myriad forms of thousands of rocks and valleys, so as to see the height, depth and width of Mount Zhongnan. In fact, it is slightly similar to Wang Wei's "Harmony with Meteorology", but the style is different.
