May 1, 2010, at the Hefei Human Settlements Expo, a "mimi villa" attracted much attention. This "mimi villa", which is only two square meters, can be transformed into a card-type writing desk or a reception room, and also has cooking utensils to solve the problem of dining. The designer, a low-carbon enthusiast, introduced that this "mimi villa" might be the smallest "home" in the world.
