Chessboard introduction: There are primary and secondary squares on the north and south sides of Sun Tzu Art of War City. The south square outside the main entrance especially highlights the style of military confrontation. It is paved with granite and has an overall symmetrical layout. In the center of the square is a Chinese chess board symbolizing the confrontation between the two armies. The Chu River and the Han boundary are used as the main passage from the square to the tourist area. Chess pieces are arranged vertically on both sides. It looks like a fountain, with nine chess pieces on the east and west sides, arranged in a formation. The east and west boundaries of the square are trimmed into battlement-shaped hedges with green shrubs, and grass-shaped shields are planted on the inner slopes of the hedges. There are a set of "weapon rack" type lighting lights in the northeast and northwest corners in front of the square. Eighteen lamp posts are made in the shape of eighteen weapons. There are elevated decorative lights in the east and west of the square that are shaped like bell racks. There is a lying stele in the middle of the south of the square, with "Chinese Sun Tzu Art of War City" engraved on the front in Chinese and English, and the city stele inscription written by the Huimin County People's Government on the back. A large shield pool is set at the bottom of the back, and the pool is covered with various flowers and plants.
