On the other hand, the background after this work used deep blue, and It made environment quiet and darkness. The only light was come from the top and deviated left hand. That spotlight made a shadow of sculpture on the deep background wall. Furthermore, those shadows, dusky light and peaceful environment are the other parts of the “Bridge”. In the shadow, audiences can clearly see some people are walking thought a bridge, and there were an old and shabby tower with a fan stay on a side of bridge. Although those people looks normal, doesn’t like the real first part’s characters have deformed limbs. Some of them are hunchbacks because they had carried something heavily, some of them moved hard and carried a weighty gunnysack on the arms, and others are ready to shoulder the heaviest loads. By the way, the winnower might use manpower and material resources sparingly. Therefore, all of them are face on the same way. It may be a story about the slavery society of antiquity. They had got the instruction from their master to build the winnower. And it also can be another story which talking about somebody impoverished and backward living in straitened circumstances. They had lost their job because the factory had got a new winnower, so the factory didn’t need workers anymore. Those people had no idea except to found some harder work and get less money for living. However, the shadow made by spotlight was not only like a picture with the language of black and white but also like one of the cinema scenes in the silent film. Exclusive of a shock come from the colourful painting or an exquisite masterpiece with exquisite lines in drawing, succinct outline and strong contrast between black and white can give more space for people to image.
