Every weekend. Fosun Art Center, located in the Bund Financial Center, is a non-profit organization initiated and funded by Fosun Group and Fosun Foundation. The outer wall is wrapped in a three-layer curtain wall structure, and it can also move, which has both a three-dimensional sense and an artistic sense of bending and flowing, and is called "dancing building". The mechanism will start the all-day rotation mode every weekend, and the outer wall will start to rotate, which is very beautiful.
