"Yijian" is a coffee brand affiliated to netease in China. It is not only a cafe with atmosphere, but also a multi-functional space, providing people with communication and interaction. It can meet the needs of small performances, salons, exhibitions, offices and conferences. There are two doors in the space, which are important channels leading to other Spaces. The plane is divided into large and small rectangular areas by the channels, which are divided according to functions. Three "boxes" are placed in the site and different positive and negative Spaces are generated through different openings in the box. It satisfies all kinds of different functions, such as bar area, multi-function area, booth area and so on. Different opening directions and scales of the box present interesting contrast and rhythm: private and open, real and empty, dark and bright, conveying different spatial emotions. When people move around inside, the relationship between space and people, as well as the relationship between people, becomes closer and more interesting, and an immersive spatial experience is achieved at the same time.
