Li Yu, a poet in the Song Dynasty, wrote the poem Nostalgia in the East Building of Xianyang City. There is a famous sentence in the poem, "When it is important, come here for a visit, the eternal building in the west of Xianyang City", which expresses his admiration for the civilization left by the ancients.
The East Building of Xianyang City is the work of Xu Hun, a poet in Tang Dynasty. The whole poem is full of scenes and emotions, and the poet endows abstract feelings with shapes through the description of scenery, which not only presents natural scenery, but also embodies rich life experience and profound thinking about history and reality.
