Zhengzhou Xigang Jianye Exhibition Center is a product hall that gathers many well-known domestic real estate companies. The architectural plan is to spread the park in the form of Big Dipper. The landscape design uses a polyline form to echo the architecture and organize the landscape space. The experience of multi-dimensional changes in detail in the continuous upward movement, forming an integrated art with rich layers and interesting overlaps with the architecture, creates an extraordinary, fresh and powerful public space.
