The king of Qin swept Liuhe, eyeing up, he Xiongzai! Swords make clouds, and princes come to the West. "(Tang Li Bai's" Antique ")
"Goat Tongguan Nostalgia" is a Sanqu by Zhang, a writer in Yuan Dynasty. This is what he did when he went to Shaanxi for disaster relief through Tongguan. Looking back, this song, from the rise and fall of dynasties to the sufferings of the people, points out the opposition between feudal rule and the people, and shows the author's thinking about history and sympathy for the people. The starting point of this kind of sympathy and care is the Confucian thought of helping the people by running the country, which is common in the traditional five-seven-character poems, but rare in the Yuan Dynasty Sanqu. The whole song adopts a layered and in-depth way, from writing scenery to recalling the past, to triggering discussion. It perfectly combines boundless scenery, deep emotion and elaborate exposition, and has a strong appeal. The lines between the lines are full of historical vicissitudes and a sense of the times, which not only has the characteristics of nostalgia for ancient poetry, but also has a distinct depressed style.
