The vicissitudes of history in the past carry many thousands of years. Daydreams, the elegant scent of books in the pen and inkstone, thoughts and friendship brewing in the wind, the story of Shui Tiao Ge Tou is still sung, Jiang Feng and the fishing fire are safe, the endless poems I read are in my heart, and I write each word step by step into a chapter.
