According to ancient books, when the grandfather of Uncle Xu Jian, a native of Suzhou, was living in the countryside, one day there was thunder and the house was shaken. Suddenly, a flash of lightning flashed, and thick smoke suddenly appeared, covering the sky and the sun. The room was also filled with fireworks, making it impossible to see anything clearly. It took about an hour for the smoke to slowly dissipate. Uncle Xu Jian's grandfather was surprised to find that the pillars in the room had been cracked and there were many footprints like dragon's claws left around. He opened the wooden box again, and the platinum vessels inside were melted into beads and scattered in a pile. Looking at the lock on the wooden box, it was intact. I really don't know how this magical thunder and fire melted the metal in the wooden box.
