"Chi Ri Jiang Shan Li" comes from "Two Quatrains" written by Tang Dynasty poet Du Fu. The original poem is as follows:

Two Quatrains

Tang Du Fu

The country is beautiful in Chiri, and the spring breeze is fragrant with flowers and grass.

Swallows fly when the mud melts, and mandarin ducks sleep in the warm sand.

The blue birds in the river are more than white, and the blue flowers in the mountains are about to burn.

This spring has come and gone, and when will it be the return year?
