I lay sprawled in my lonely country, not feeling sad about my situation, but thinking about defending the frontier of the country. The night will be over, I lie in bed listening to the sound of wind and rain, in a daze in my dream, riding an armored horse across the frozen river to the northern battlefield. "Sleeping in the middle of the night listening to the wind and rain, iron horse glacier dream", inherited the last two poems. When the author fell ill in a remote village and couldn't sleep at midnight, he felt the wind and rain in nature more truly. The sound of wind and rain reminds the author of the ups and downs of the country and the sudden change of war, and the military life of that year seems to be presented again.
