Story:
Legend has it that in the Xianyang Palace during the Qin Dynasty, there was a magical mirror.
It was four feet wide and five feet tall, capable of reflecting people from both sides. When someone stood before it, their reflection appeared inverted.
If one pressed their hand to their chest while looking into the mirror, it could reveal their internal organs, identify ailments within the body, and even expose individuals with malicious intentions.
Emperor Qin Shi Huang often used this mirror to scrutinize those around him.
