In March 1932，the Japanese military established the “Manchuria”. In order to achieve its comprehensive rule，the Japanese military not only suppressed and ruled the Northeast region of China in terms of economy，politics，education，etc.，but also vigorously promoted “Manchuria” as an “ideal hometown” in Japan，and issued policies such as “Manchuria Expanding Immigration”，“Manchuria Youth Volunteer Army”，and “Mainland Bride”，making more Japanese choose or be forced to “cross Manchuria”. Among them，there are a group of “Manchuria crossing people” who have different life experiences and “Manchuria crossing” positions. Under the influence of the continuously changing policies issued by the Manchurian puppet authorities，some of Japanese writers began to create their works on “Manchuria” during the “Manchuria” period，while others，after experiencing defeat and return，wrote about the unique and alternative “scenery” of “Manchuria” in literary history. Among them，Miyao Tomiko is one of the few female writers who，after the end of the war，created novels based on her own experience in “Manchuria”. As one of the four autobiographical novels by Miyao Tomiko，Shu Ka is based on the reality of “Manchuria”，with the content written from a unique female’s perspective，focusing on the survival situation of “Manchuria’s expanding immigrants”. By meticulously describing the trivial details of what people consider to be the “family trifles” in the life of “crossing Manchuria”，to some extent，it truly reflects the social situation during the “Manchurian” period，thus revealing the truth of Japanese invasion of China and persecution of the Chinese people.
