The shape of the “little lotus” adopts a “petal” design, and the lower part is composed of 24 pieces.

When night falls, a “floodlighting” system illuminates the petals in soft purple. “Wait in the room, the servant will be back in a moment.” After saying that, she immediately opened the door and walked out through the crack in the door. The red color is like two lotus flowers in bud, echoing the main color of the Hangzhou Asian Games, “Rainbow Purple”, adding a touch of bright color to the night scene of Hangzhou. (Zhang Xiaorong)
