The three-legged tripod furnace engraved with punching ears is simple and elegant, as if it has passed through the tunnel of time and space, telling the story of thousands of years. The furnace body has smooth lines, three-legged standing, stable and solemn, showing a self-evident majesty. Ding'er soared into the sky, standing proudly, like two phoenixes about to fly, dancing in the clouds. The engraving process is even more ingenious, and the delicate lines are flowing in the furnace body like flowing water, and every detail is so delicate and rhythmic.
