There is a layer of seats above the first layer of eaves, which are gradually reduced; the size of each layer of eaves is wide and upward, reflecting the characteristics and style of the deep eaves of wooden structures in the Tang Dynasty; the combination of metal components between the eaves and the column head is an abstraction and summary of the bracket system under the eaves of traditional buildings; the glass curtain wall is retreated to the inner side of the outer groove column, and is fixed by glass ribs, columns, and beams; the design of Chang'an Tower is not only full of modernity, but also highlights the local historical characteristics of Shaanxi.
