The original poem is:
The general has not yet raised the border, and the children of Huxiang are full of Tianshan mountains; Xinliu is three thousand miles away, and the spring breeze passes through Yumenguan.
Poetic:
Praise the great achievements of Hu Xiang army led by Zuo in recovering lost land in Xinjiang. The whole poem means that the general's ambition to lead the western expedition has not been realized. We still see Huxiang children all over Tianshan Mountain. You see, the Qing army of the Western Expedition brought spring to the frontier and let the spring breeze blow outside Yumen Pass.
