Introduction to bronze sculptures: A large bronze sculpture "Time and Space" stands in the central square of the museum. It consists of three imitations of the door-edge lifting beams on bronzes of the Shang Dynasty, a four-legged bronze nugget imitating the national treasure-level cultural relics of the Shang Dynasty and a crouching bird. The double-tailed tiger and the torch are composed of four parts, implying a splendid civilization with a long history; abundant resources and natural treasures, outstanding people; and a single spark can start a prairie fire.
