1, the desert is lonely and straight, and the long river falls in yen. -Wang Wei's March on the Fortress

Lonely smoke rises to the sky in the vast desert, and the sunset is round by the Yellow River.

2. Sunrise is better than fire, and the riverside is as green as blue. -Bai Juyi's "Recalling Jiangnan"

The sun rises from the river, making the flowers on the river brighter than red, and the green river is greener than the blue grass.

The clouds are sinking in the morning, and the rain is coming. -Xu Hun's "East Building of Xianyang City"

Outside the pavilion, the clouds burst into red, the sun set, Shan Yu didn't arrive, and the wind had blown all over Xianyang Tower.

4, light clouds are far away, cold days are red. -Xu Changtu's "Linjiang Fairy Drinks from Tingxi"

The sunset is infinitely beautiful and buried by the coming night. -Li Shangyin's Leyuan Scenic Area
