Sadness is an abstract emotion. Li Yu turned the hard-to-see emotion into something visible, which made people really feel it. The biggest river is the Yangtze River, and Nanjing, the capital of the Southern Tang Dynasty, is very close to the Yangtze River. Therefore, Li Yu, the king of national subjugation, used the water of the Yangtze River as a metaphor for the pain of missing the motherland, which was profound and impressive. "One River" is meaningful. In spring, the snow melts and disappears, and the river has the largest amount of water. It is endless to use "spring water" as a metaphor for sadness. A river of spring water flows eastward, and the waves are layered on top of each other, just like the new worries overshadow the old ones, which is endless. Li Yu's sadness is not the lingering love and lovesickness, but the hatred for his country, so it is more appropriate to use the majestic spring water as a metaphor, and there is a kind of deep affection that depends on mountains and rivers.
Author Li Yu (937-978), the monarch of the Southern Tang Dynasty during the Five Dynasties and Ten Kingdoms period, reigned for (96 1-975), and was also the most melancholy poet in the Five Dynasties. The word shigemitsu, the first name from Jia, number Zhong Yin. Lotus lay man Xuzhou (now Jiangsu) people are called Huzhou (now Zhejiang) people. The sixth son of Li Jing in the Southern Tang Dynasty, he succeeded to the throne in the second year of Song Dynasty (96 1), and was called the late master in history. In the eighth year of Kaibao, the country broke the Song Dynasty and was captured to Bianjing, where he became a general and disobeyed orders. Later he was poisoned by Song Taizong. Although Li Yu is politically incompetent, his artistic talent is extraordinary. Li has certain attainments in books, paintings, songs, poems and essays, especially in ci. There are about 32 existing Li Yu's ci poems, the contents of which can be mainly divided into two categories: the first category was written before the Song Dynasty, which mainly reflected the court life and the love between men and women, and the subject matter was narrow; The second category is that after the Song Dynasty, Li Yu was deeply saddened by the national subjugation, and his memories of the past were full of his own feelings. The achievements of his works in this period far exceeded those in the previous period. Among them, masterpieces such as Young Beauty, Langtaosha and Night Cry were all made at this time. In this period, most of the ci poems were based on sadness, mainly describing the scene of dreaming from afar, and expressing infinite nostalgia for "the old country" and "the past". Li Yu occupied an important position in the history of China's ci poems and was called "the emperor of eternal ci poems". It also has a great influence on future generations. He inherited the tradition of Huajian poets since the late Tang Dynasty, but reflected a certain artistic conception with universal significance in real life through a concrete and sensible personality image, which promoted the creation of ci and expanded the field of expression of ci. Li Yuwen is rich in writing, poetry, books and painting. His ci poems are mainly included in two major ci poems in the Southern Tang Dynasty.
