In the 17th episode of "The Apothecary Diaries," Maomao and Jinshi embark on a secret journey into the heart of the city, both in disguise to blend in with the common folk. The story unfolds as Maomao, known for her ability to make the beautiful appear ordinary, uses her skills to transform Jinshi into "Jinka," a man of the people. Despite the transformation, Jinshi retains his striking appearance, hinting at the indescribable charm exuding from his disguise.

The episode features a playful exchange between Maomao and Jinshi. While Maomao introduces Jinshi to the simpler joys of communal living, including eating chicken skewers, their interactions reveal deeper undercurrents of mutual, yet unacknowledged affection. Jinshi's attempt to engage in a more meaningful conversation highlights his desire for a closer relationship, which Maomao meets with her characteristic pragmatism, focusing on the immediate pleasures of their outing.

As the day progresses, Maomao's worries about her adoptive father come to the fore, revealing a personal dilemma between her current life in the palace and her familial obligations. Jinshi learns of her father's unique medical knowledge, sparking his curiosity as to why, despite these valuable skills, they live in modest circumstances.

The episode takes a reflective turn when Jinshi inquires about the mechanisms of value in the world of courtesans—a question Maomao finds distasteful but answers with revealing clarity. She explains the dichotomy between physical beauty and virtue and how these elements contribute to a courtesan's worth. This discussion not only sheds light on the complex social structures of their world but also subtly reflects the protagonists' own values and perceptions.
