The rotation of lenses because of the wind
The lens wall not only provides the ventilation needed for indoor crops, but also enhances the interaction between indoor and outdoor and becomes a bridge between rural and urban areas. The wind which is an irresistible force will make the lens rotate because the lenses are suspended on the wall by a string. As mentioned above because of the property of lens, the rotation will cause the distortion of the image. But both countrymen and urbanite inside and outside the building can actively rotate the lens and avoid distortion of the image, changing the angle the wind brings to them. Projecting this design into reality, wind implies the expansion of urban into rural, which is the result of national development and is irresistible. Neither rural nor urban people can stop it. Distortion of the image caused by rotation means the barrier between countrymen and the urbanites which makes both sides cannot see the real and positive side of each other. The reasons of the barrier are complex, including different stereotypes in their mind for each other because of some reason, the accumulated conflicts between the two sides in daily life, etc. The active behavior of people to rotate the lens to change the angle originally brought by the wind implies that urban and rural people can choose to weaken the barrier in their life actively. And they should integrate into the new life with active behaviors, and such active interaction can alleviate the obstacles and frictions between them. Although the two sides have to live together due to irresistible force, it does not mean that there are only obstacles between them. They can choose to actively blend into each other's lives, communicate, and learn from each other's strengths.
