Maomao is 17 years old at the beginning of The Apothecary Diaries. Volume 1’s opening chapter gives this age directly. This is the starting-age answer for viewers beginning the anime as well as readers starting the novels.
For Maomao and Jinshi’s age gap, continue to the identity-spoiler section. Later novel ages are listed separately under the age timeline, so ages from different points are not mixed together.
How Old Is Maomao at the Start?
The opening chapter of Volume 1 describes Maomao as seventeen. Volume 1, Chapter 28 refers to the same age when discussing her knowledge and composure.
How old is Maomao in the anime? She begins the story at 17. An exact age in a later episode needs a corresponding story reference; a new season or a change of employer does not automatically mean a birthday has passed.
Her petite appearance can make her seem younger, but appearance is not an age reference. Use the narrative’s stated ages rather than estimating from character designs.
Maomao's Background: Life Before the Rear Palace
To fully grasp Maomao's maturity and cynical worldview, we have to look at her upbringing. Maomao's life at the Verdigris House--a high-end brothel in the pleasure district--exposed her to the harsh realities of the world at a very young age. She saw how women were treated, the tragic consequences of disease, and the dark side of human desires.
Her practical worldview was further shaped by her adoptive father. Luomen teaching Maomao pharmacy skills is the bedrock of her character. Luomen, a disgraced former court physician who studied in the West, passed down highly advanced medical knowledge to her. This education is what ultimately allows her to survive and thrive when her life takes a sudden turn.
But when did Maomao enter the palace? She was kidnapped by human traffickers and sold into servitude in the Rear Palace when she was just 17.
Her family history explains much of her guarded outlook, but it is not needed to calculate her starting age: Volume 1 states that directly. For a broader introduction to her surroundings, see the setting and time-period guide.
Identity and Later Novel Spoilers Below
The next sections reveal Jinshi’s cover identity and real age. The timeline also includes a stated age from Volume 12. Stop here if you only want Maomao’s starting age.
How Old Is Jinshi? His Stated and Real Ages
Jinshi’s public identity and his real age must be kept separate. His position at court makes the distinction part of the plot.
In Volume 2, Chapter 14, the eunuch persona “Jinshi” is described as 24, while Gaoshun identifies the prince’s actual age at that point as 19. These are two ages attached to different identities in the same chapter.
Do not combine the 19-year-old reference from Volume 2 with Maomao’s opening age from Volume 1 and call the result their exact age gap. Those figures come from different points in the narrative.
The Elephant in the Room: Is Jinshi a Eunuch?
Because Jinshi manages the Rear Palace--a place strictly forbidden to intact adult men to ensure the Emperor's bloodline remains pure--many fans ask: is Jinshi a eunuch?
Jinshi’s eunuch persona is a cover. Volume 2, Chapter 14 distinguishes that identity from the prince and discusses the medicine used to maintain it. His apparent age therefore should not be treated as his biological age. For the identity story, see Jinshi’s real name and hidden role (identity spoilers).
The Maomao and Jinshi Age Gap
Jinshi is about one year older than Maomao in the story’s stated ages. In Volume 3, Chapter 14, Maomao recalls that the Emperor’s younger brother is one year older than she is. This direct comparison is the useful reference for their age gap.
The apparent larger gap comes from Jinshi’s 24-year-old cover identity. Mixing that persona with his real age, or comparing ages from different volumes, produces misleading answers.
Their small age difference does not erase the much larger difference in rank and power. Age helps explain their youth, while palace status explains many of the practical obstacles in their relationship.
Historical Context: Adulthood and Marriage Customs
The story places young characters in demanding jobs and political marriages. Those fictional social expectations should be distinguished from both modern legal adulthood and the varied customs of historical China.
Is Maomao Considered an Adult?
Maomao works as an apothecary and poison tester while still in her teens, but holding a job is not the same as having full control over her life. Her abduction, service contract, and low rank limit her choices. A single real-world coming-of-age ceremony cannot establish her legal status in this fictional empire.
Ages of the High Ranking Consorts
Volume 1, Chapter 27 gives the following early-story ages for the senior consorts:
- Consort Lishu: The youngest of the four top consorts, Lishu is only 14 years old. Her young age makes her a target for bullying by her own ladies-in-waiting, and Maomao often views her with a sense of pity and protective duty.
- Consort Gyokuyou: The Emperor's favorite and Maomao's first primary employer, Gyokuyou is 19 years old at the start of the story.
- Consort Lihua: The proud Crystal Pavilion consort is around 23 years old, considered incredibly mature and established within the Rear Palace hierarchy.
Understanding these ages puts Maomao's interactions into perspective. When she advises Consort Gyokuyou, she is speaking to a woman only a year or two older than herself, yet separated by a massive chasm of social class.
The Apothecary Diaries Story Timeline and Growth
Maomao grows older over the course of the novels. The table below lists two explicit textual checkpoints, rather than assigning an age to every season or volume.
| Story point | Age | Reference |
|---|---|---|
| Opening story | 17 | Volume 1, opening chapter; Chapter 28 |
| Later novel milestone | 21 | Volume 12, Chapter 30, after the new year |
These are the ages stated in the text. The Volume 12 passage connects her age with the new year; it does not establish a birthday in a particular anime episode. Chapter titles and numbering can vary by edition.
How Long Maomao Served the Consorts
Maomao first serves in the Rear Palace and later works under different arrangements outside it. Those moves help locate events in the plot, but they should not be converted into exact ages without an accompanying time reference.
Tracking how long Maomao served the consorts versus how long she serves as a medical assistant in the outer court is a great way to map the overarching timeline of the series.
Character Growth and Light Novel Differences
One of the most rewarding aspects of the series is Maomao character growth and maturity. While she starts as a highly guarded, cynical teenager who only cares about rare poisons, her time in the palace forces her to develop emotional intelligence and a begrudging sense of empathy for those caught in the web of imperial politics.
For readers of the light novels and their adaptations, Volume 12, Chapter 30 provides a clear later checkpoint: Maomao is 21. This is a specific reference, not a claim that every volume from Volume 10 onward depicts her at the same age.
Maomao and Jinshi Relationship Progression
As the novels progress, their relationship is shaped by Maomao’s work and Jinshi’s political responsibilities. A small age gap does not make their social positions equal.
The fact that they are essentially the same age allows them to grow together. Jinshi drops his "perfect celestial nymph" persona around her, revealing his genuine vulnerabilities, while Maomao slowly lowers her defensive walls, acknowledging that Jinshi is one of the few people she genuinely trusts.
Tips for Enjoying the Series Timeline
To fully appreciate the passage of time and character growth in The Apothecary Diaries, keep these actionable tips in mind while reading or watching:
- Watch the Seasons: The author uses environmental clues (snow, plum blossoms, summer heat) to mark the passage of time.
- Track Story References: Jobs and clothing help identify an arc. Use explicit ages and new-year passages before assigning a year to that arc.
- Note the Court Politics: Promotions, pregnancies, and shifting alliances among the Emperor's consorts are the primary ways the series tracks the passing years.
Conclusion
Maomao starts at 17; Volume 12, Chapter 30 later states that she is 21. Keeping those reference points separate answers the age question without inventing an episode-by-episode birthday schedule.
Jinshi’s 24-year-old cover identity and his real age are different facts. For their age gap, the direct one-year comparison in Volume 3 is more useful than subtracting numbers from different volumes.
