What's urgent about the essays and poems about wild vegetables?

Zhou Nanjuan in The Book of Songs

Picked and picked, half a day less than a small basket. I miss my lover, and the food basket was abandoned on the road. When climbing the high Rocky Mountain, the horse's feet were down. Let's pour a golden pot of wine first to comfort me. Climbing up the high mountain ridge, the horse's legs are already soft and confused. Fill my glass and keep me away from my inner sadness. I'm sorry, but I'm sorry I'm so tired, why bother!

Pick, pick, pick, turn your ears up, and less than a small basket for half a day. Missing my sweetheart, the vegetable basket was abandoned by the roadside. Climbing that high rocky mountain, the horse was exhausted. Fill the golden pot of wine first to comfort my thoughts and sadness. Climbing the mountain back, the horse's legs are weak and confused. Fill a large glass of wine first, lest I feel sad. Climbing up the rocky hill with difficulty, the horse fell to one side exhausted, and the servant was exhausted, but helpless and worried! [ 1
