"Flies", one of Yokohama's famous works, was published before the formation of the New Sensational School, but the specific literary expressions appearing in this work are completely connected with the creation of the New Sensational school later, causing repercussions in the literary world. Therefore, this paper adopts the text analysis method to explore the montage skills in "Flies" from the aspects of lens scheduling and sound composition, and peeks into the predestined love towards film of Yokohama. "Flies" consists of ten relatively independent shots, and this composition is connected by big-eye flies. Through the big-eyed flies, the tragedy was presented. The various characters who have different lives were sitting in the same carriage, and together they were going to be involved in the scene of a car crash. Skillfully using the techniques of montage, Yokohama lets readers see the weakness and powerlessness of people from the perspective of flies.
