On the surface, she is the female shopkeeper of "Wenxiang Nephrite", the number one incense shop in Beijing. She is frail and sickly, and speaks in a soft voice (murmuring). In fact, she is the daughter of the chief widower of the previous dynasty who was unjustly killed. She has a keen sense of smell and can reconstruct the last scene of the deceased through the faint smell emitted by the corpse.
