There are other poems like this: The country is broken, the mountains and rivers are there, the city is springy and the vegetation is deep. The flowers shed tears when I feel grateful, and the birds are frightened by the hatred. The war rages on for three months, and a letter from home is worth ten thousand gold. The white-headed hairpin is shorter, and the hairpin is full of lust. Yesterday there was faith in the mountains, but today it is time to farm. Rumor has it that Du Lingsou blamed me for returning to the mountain late. I drink alone in the pond and play chess in the forest. I remember your place in the east stream, lying idle in front of the cormorants.
