The architect uses a large area of natural wood color vertical sheet sequence to arrange a wavy curved surface on the top visual element of the interior space, supplemented by five grooves with a width of 40 cm to distinguish the boundary. For the facade of the groove, the warm light color lamp belt is selected for scrubbing uniform expression and the node design of the hidden lamp is carried out at the same time. In the end, the undulating bands of warm light colors not only express the orderly but naturally undulating wooden vertical slices in an "inverted Xishan"form at the top of the room.
