Introduction to the central square: The main square divides the green space in the shape of a "ding". The four legs of the "ding" are tourist paths extending in all directions. The body of the "ding" is paved with Anxi red and Taihang red granite, making it the largest in the country. The chessboard symbolizes that Xuzhou has been a battleground for military strategists since ancient times. The green space uses a large piece of evergreen lawn imported from the United States as the background color, and retains the original large trees and ornamental pomegranate trees, creating the effect of "there are flowers under the trees and trees under the flowers".
