In this painting, van gogh shows real civilians with crude models. The painter himself said, "the point I want to make is that by the light of an oil lamp, the potato eaters use their hands, which work on the ground, to grab the potatoes from the plate-they honestly live on their own."

Van gogh painted a vivid picture with exaggeration. The sky of movement and change. Convey the author's inner anguish and melancholy.

Through the series, van gogh expressed his understanding of life and showed his unique spiritual world.

Capture the instantaneous change of color from the light, show with the auditorium mixing technique of color. The fever of his spirit carried him to the vast realm.
