The sound of drums and horns from the fifth watch is tragic; The Three Gorges reflected the Milky Way Star and rippled with the river waves. Zhuan Xu inherited Cold Night and wrote what he saw and heard at night. "Drum horn" is the drum sound and horn used by the ancient army to tell the time and give orders. At that time, although the Anshi Rebellion had been put down for several years, there were wars everywhere. In ancient times, the night was divided into five watches, and the "five watches" were close to dawn. At this time, people are awake, and the sound of drums and horns is more tragic and moving. This highlights the atmosphere of non-stop troops, turbulent situation and frequent wars from the side. Although the Milky Way in the sky is spectacular, when it is reflected in the Xiajiang River, it shows a broken and swaying scene because of the rushing river, which seems to be somewhat similar to the poet's stormy life and the chaos of the current situation. These two sentences are desolate and vigorous in tone, forceful and beautiful in wording. In addition to the "great beauty" mentioned in Dongpo Zhi Lin, they also contain the poet's tragic and deep feelings. As Liu Chenweng said, "The third and fourth sentences are infinitely sad."
Ye Mengde's Shi Lin Shi Hua commented: "Seven words are hard to be vigorous and powerful, but each sentence is powerful, but the implication is not lost. Because of Lao Du's sentences of "beautiful spring, flowing water, floating between heaven and earth, like a jade peak and a cloud, from ancient times to the present" and "Stark sings the fifth watch, the drum is ringing, and the Three Gorges Galaxy", they often hate those who have no successors.
