Introduction to the viewing platform: The viewing platform has the best viewing angle to look around the landscape of the Garden Expo. The open water surface reflects the Cloud Support Towers of Huangni Mountain, Ma'an Mountain and Langshan into the water. Inlaid on the steps of the viewing platform are three "technology trees" designed with high technology, which can provide shade for visitors during the day and present a scene of fiery trees and silver flowers at night.
