Inspired by the design of "Fei river form" of Hefei Mother River, the designer follows the concept of art design of Fei river curve and introduces the art elements of flowing space into the interior space. The designer applies the feeling of waves and fluctuations in the water to the indoor space. The neat wooden waves at the top are interwoven with the rhythmic visual aesthetic feeling in the clouds and running water. The winding and flexible rotating staircase gives space a sense of future, just like a long and gentle ribbon, which visually presents a vast continuity.
