Introduction to the square gatehouse: Behind the archway is a square of nearly 30,000 square meters. A large sculpture stands in the center of the square, dividing the square into two parts, the inner and outer parts. The outer square is a parking place for vehicles crossing the bridge, a short stay for tourists, and a commercial service area; the inner square is a management organization and service organization. The northeastern part of the square is the gate tower of Sunbin Tourism City, and its midpoint is on the same central axis as the Yuanrong Bridge. Above, the main building is 80 meters long, 24 meters deep, and 27 meters high; there are 60-meter-long castles and turrets on both sides. The entire city gate tower is similar to the "Meridian Gate" of the Forbidden City.
