1. The grass is dry and the hawk's eyes are weak, and the snow is gone and the horse's hooves are light. ——Wang Wei of the Tang Dynasty, "Watching the Hunt" 2. The bitter wind blows and the frost flies, and the goshawk knocks over the dawn. The clouds are covered with mist, the rainbow is broken, and the thunderbolts are flying across the mountains. The thorns and thorns are strong, and the foxes and rabbits are snatched from the sky. The claw hair kisses the blood and hundreds of birds pass away. When I look around independently, I am excited. The scorching wind and heat suddenly come, and the wings fall off and destroy themselves. The coypus in the grass are infested, and they are frightened and injured overnight. ——Tang Dynasty. Liu Zongyuan's "Caged Eagle Ci" 3. Why should you attack ordinary birds and spread their hair and blood on the grassland?
——"Painting Eagle" by Du Fu of the Tang Dynasty
