Dimension is a basic concept of geometry and space theory. Zero-dimension is an infinitesimal point. One-dimension is an infinite line with only length. Two-dimensions is a plane. Plus the height, the concept of three-dimensions “Dimension” is another tea tray for single, which is made by black stone. By taking the advantage of the height gradient drop and forming two to three dimensional changes , the kind of tea tray can realize the natural flow of tea under the tea-making scene. So the dimension creates a simple and personal experience of making tea.
