We advocate the poetic plain nature. The impressionism, a form between realism and abstraction, is neither too simple nor too complicated. It leads people to feel, to experience and to appreciate the whole and parts of the space, under a kind of familiar psychological effect. The impressionism contains momentary inspiration and passion of life so as to get closer to the nature of the space. By creatively developing the cultural spirit of building, getting rid of the traditional constraint, adding new design ideas and elements, the design makes a unique style. It will be the symbol of avant-garde and become the mainstream of the future.
