Many ancient poems have these images, because they are very common images in ancient poems. The pavilion is only on the way to farewell, so it is often used to write farewell. For example, Li Bai: Long Pavilion and Short Pavilion. Mutu: You don't have to look back at the railing. My hometown is seventy-five pavilions. If not only poetry, but also flexion and fu, then there will be more. Yu Xin: Ten miles and five miles, roadside pavilion.
The ancient road also has the meaning of farewell. Bai Juyi: Sweet they pressed on the old highway and reached the crumbling gate. Green is grass. Ma Zhiyuan's Yuan Qu Tian Jing Sha: a dead vine, an old tree, a faint crow, a small bridge, a mobile family, an ancient road, a west wind and a thin horse.
It is not necessarily a good word, for example, it is actually grass. The words used are different, but they are all the same image. Another example is twilight, which can be rain at dusk, clouds at dusk, melting gold at sunset, and rain rolling with beads, to name a few.
