A poem praising "Strawberry": Farewell my friend, Li Bai, at Jingmen Ferry, and sail from Jingmen Ferry. Soon you will be with people in the south. At the end of the mountain range and the beginning of the plain, the river winds through the wilderness. The moon rises like a mirror, and the sea clouds twinkle like palaces. The water brings you the feeling of home and makes your boat travel 300 miles.
