Liangzhou Ci, Tang Dynasty - Wang Zhihuan Far above the Yellow River, among the white clouds, there is an isolated city in Wanren Mountain. Why should the Qiang flute blame the willows? The spring breeze does not pass through Yumen Pass. Note: This poem describes the majestic, desolate and lonely scene of Liangzhou, a frontier fortress. The Yellow River rushing from afar seems to be connected with the white clouds. Yumen Pass stands alone in the mountains, looking lonely and lonely. Why use the Qiang flute to play the sad willow song to complain about the delay in spring? It turns out that the spring breeze cannot blow in the Yumenguan area! Gucheng: refers to Yumen Pass. Ren: In ancient times, seven or eight feet equaled one Ren. Qiang: A nation in ancient times.
