Introduction to the theme square: Enter the gate and walk around a screen wall with a standing statue of Zhang Zeduan in front and a relief sculpture of the legendary story Along the River During the Qingming Festival at the back. This is the theme square of the park. Floating in the pool in the center of the square is a simple-looking wooden boat from the Song Dynasty, with towering masts and high-hanging sails, symbolizing the busy water transportation and superb shipbuilding technology of the Song Dynasty.
