Does the north wind rolls the white grasses and breaks them describe the harsh environment?

It is written that the weather in the frontier fortress is cold and the environment is harsh.

In the sentence "the north wind rolls the white grasses and breaks them, and the Eighth-month snow across the Tartar sky", the word "roll" means to roll up. This word vividly describes the strength of the wind, and at the same time shows the cold weather and harsh environment in the frontier fortress, and writes about the hardships of the life of the border guards. The sentence "is like a spring gale, come up in the night, blowing open the petals of ten thousand pear trees" uses figurative rhetoric to compare the snow pressure on Donglin to pear flowers. Vividly wrote the strange and magnificent scenery outside the Great Wall.

a Song of White Snow in Farewell to Field-Clerk Wu Going Home is the representative work of Cen Can's frontier poems, which was written in his second frontier fortress stage. At this time, he was highly valued by Anxi's envoy Feng Changqing, and most of his frontier poems were written in this period. In this poem, Cen Can, with the poet's keen observation and romantic style, depicts the magnificent scenery of the frontier fortress in the northwest of the motherland and the warm scene of the envoys leaving for Beijing in the frontier fortress barracks, showing the patriotic enthusiasm of the poet and frontier guards and their sincere feelings for their comrades.
