Shiba Inu usually refers to ordinary wild dogs, while the field represents the vast land and the tranquility of nature. This image is used to describe the dogs in poor farmers' homes. Because of the poor living conditions, they can only spend the night in the field. In the ancient literature of China, the image of "Chai Dog Sleeping in the Field" was widely used, representing the living conditions and social status of the poor. It is sometimes used to describe the poet himself and express his simplicity and naturalness, as well as his love for rural life and natural scenery.
