Farewell poems were one of the literary forms to express the feelings of parting. 1 "Farewell to Friends"-Li Bai of Tang Dynasty With a wave of my hand, I leave the rustling horses. You asked me if I had a date to return home. It rained at night in Bashan and flooded the autumn pool. Why should we cut the candles in the west window and talk about the rainy night in Bashan Mountain? Ascending the Mountain-Du Fu of Tang Dynasty The wind is strong, the sky is high, the apes howl, the white birds fly back to the clear sand of the mournful island. Endless trees fall and the endless Yangtze River rolls down. I'm always a guest in autumn, sad for thousands of miles. I've been sick for a hundred years, and I'm alone on the stage. I'm in trouble, bitter resentment, frosty hair, downcast hair, I've just stopped drinking. 3."Farewell to the Ancient Original Grass"-Bai Juyi of the Tang Dynasty The grass on the plain withers and thrives once a year. The wildfire never ends, and the spring breeze blows, it grows again. The far-off fragrance encroaches on the ancient road, the clear green connecting the deserted city. And send the king's grandson away, full of parting feelings. 4."Yellow Crane Tower Seeing Meng Haoran Off to Guangling"-Li Bai of Tang Dynasty My old friend left the Yellow Crane Tower in the west. The fireworks in March fell on Yangzhou. The lonely sail's shadow in the distant blue sky is gone, only to see the Yangtze River flowing in the sky. The green mountains can't block it, after all, it flows eastward. I'm worried about the river at night. I hear the flute in the deep mountains. Who thought that the west wind alone cool the yellow leaves close the sparse window? I meditate on the past, standing in the setting sun, not startled by wine, sleeping heavily in spring. At that time, the gambling book was only ordinary. The four farewell poems above were all classics of ancient Chinese literature that were widely praised and passed down to this day.
