This collection of love letters reveals an emotional secret that has lasted for twenty years in the modern poetry world. It contains the correspondence between Dai Wangshu and Shi Jiangnian, Mu Lijuan and many other women, witnessing the poet's entire process from his first love to the breakdown of his marriage. These love letters are not only candid records of private emotions, but also a laboratory for artistic creation: he sent the first draft of "Rain Lane" to his lover for advice, and practiced the combination of images in "My Memory" in the love letters. Particularly touching is "Wangshucao" written to his wife during the war, which interweaves the feelings of family and country with personal thoughts. These words are not only first-hand information for studying the poet's creative psychology, but also constitute an "emotional epic" written with tears and ink.
