External landscape introduction: The shell is surrounded by an artificial lake with rippling water. Its design concept comes from the water system of Beijing, adding a smart waterscape to the central area of Beijing. The artificial lake pool uses a water circulation system to remove turbid matter, so it does not freeze in winter and does not grow algae in summer. The lake is like a crystal-clear mirror, with waves and reflections complementing each other, supporting the huge and crystal-clear building in the center.
