Remember that Bai Juyi, a poet in Jiangnan, came to Jiangnan to avoid chaos in his early years and once lived in Suzhou and Hangzhou. In his later years, he served as the secretariat of Hangzhou and Suzhou for many years. He was deeply impressed by the mountains, rivers, grasses and trees in the south of the Yangtze River. He also forged a deep friendship with the people there, and he still loved this friendship until he returned to the North in his later years. Jiang Yinan's ci is the product of this emotion. The works express the poet's love for the great rivers and mountains of the motherland, and also play a positive role in the development of literati ci in the future.
