Each utensil is covered with a layer of smoke - the patina is smoke and the patina is cloud. The traces left by people for three thousand years are stacked together, covering the original appearance of the utensils. Shen Yulin was born with a pair of magical eyes that could see through this layer of smoke. He is the boss of Juguzhai, a profit-seeking businessman in the eyes of others. The Japanese came to him to appraise the treasure. He quoted the price with a smile, then turned around and replaced the real one with a fake one. The artifacts did not speak, but after the smoke cleared, the truth began to echo from three thousand years ago.
