Qin Quan: Qin unified the weights and measures after the reunification of the six countries. "Quan" is the scale used to weigh the weight; "Qin Quan" pot is just like its appearance. The earliest Qin Quan pot used ring ear handles. Later, I don't know who did it, and I changed it to a dragon-shaped handle. Qin Quan is a pot, he is calm, and he is just alive. There are thousands of images in the ancient and clumsy, and Gu Lao made Qin Quan the pinnacle of the prime device.
