Jinshi is a massive lie. Well, his existence isn't a lie, but everything he presents to the world of the Rear Palace is a carefully constructed performance designed to keep him alive and keep the imperial line from collapsing into a pile of ash. If you’ve been watching the anime or reading the light novels by Natsu Hyuuga, you know that the mystery of the Apothecary Diaries Jinshi family tree is basically the engine that drives the entire political subplot. It’s messy. It's confusing. Honestly, it’s a bit of a tragedy once you realize how many people had to suffer just so he could exist.
Maomao sees through it eventually, of course. She’s too sharp not to. But for the average viewer, trying to map out who Jinshi is related to feels like trying to untangle a spiderweb while wearing oven mitts. You have the Emperor, the Empress Dowager, the "Little Brother," and a whole lot of dead infants.
Let's break down the bloodlines.
The Public Lie vs. The Private Truth
In the beginning, we are told a very specific story. Jinshi is a eunuch. He’s the administrator of the Rear Palace. He is, supposedly, the younger brother of the current Emperor. This would make him the son of the previous Emperor (the one with the... questionable tastes) and the Empress Dowager.
It’s a clean story. It explains his beauty. It explains his authority.
But it’s fake.
If you look closely at the Apothecary Diaries Jinshi family tree, the branch he claims to be on is a total fabrication. Jinshi is not a eunuch. He’s a "man of the clouds," a member of the imperial family with his "equipment" fully intact. The "Little Brother" title is a cover-up for a much more scandalous reality. He isn't the Emperor's brother; he is the Emperor's son.
The Baby Swap That Changed Everything
To understand Jinshi, you have to understand the night he was born. This is where the story gets dark. Years ago, two women were giving birth at roughly the same time. One was the current Empress Dowager (who was then the favorite consort of the previous Emperor). The other was Ah-Duo, the current Emperor’s first and most beloved consort.
Ah-Duo’s birth was a disaster. Because of a medical complication and a lack of available doctors—partially because the Empress Dowager was also in labor and hogging the medical staff—Ah-Duo lost her fertility. Her child survived, but barely.
Meanwhile, the Empress Dowager also gave birth to a son.
Here is the twist that defines the Apothecary Diaries Jinshi family tree: The babies were swapped.
Ah-Duo, fearing for the life of her son and perhaps seeking a bit of revenge or security, switched her child with the child of the Empress Dowager. The baby everyone thought was the Empress Dowager’s son—the "Little Brother"—actually died of SIDS (Sudden Infant Death Syndrome) or a similar complication shortly after. The baby that survived, the one being raised as the Empress Dowager’s son, was actually the son of the current Emperor and Ah-Duo.
That survivor is Jinshi.
Mapping the Real Bloodline
If we strip away the titles and the lies, here is what the actual biological tree looks like.
The Father: The Current Emperor
The Emperor is Jinshi’s biological father. He knows this. Or at least, he suspects it strongly enough that it influences every interaction they have. The Emperor treats Jinshi with a mix of frustration and extreme protectiveness. He wants Jinshi to take his rightful place as the Crown Prince, but Jinshi—ever the rebel—prefers to hide in the Rear Palace playing the role of a beautiful eunuch.
The Mother: Consort Ah-Duo
Ah-Duo is the tragic figure in this equation. She gave up her son to save him. By swapping Jinshi with the Empress Dowager's baby, she ensured he would be raised with a higher status and protection, even if she could never publicly claim him. When Maomao finally pieces this together during the Honey Leaf arc, it’s heartbreaking. Ah-Duo isn’t just a former consort; she is a mother who has had to watch her son grow up from a distance, pretending he belongs to someone else.
The "Mother": The Empress Dowager
She is biologically Jinshi's grandmother. However, in the eyes of the law and the public, she is his mother. This creates a bizarre dynamic where the woman raising him is actually the mother of his father.
Why the Swap Matters for the Plot
Why go through all this trouble? Why does the Apothecary Diaries Jinshi family tree have to be so convoluted?
Politics.
In the world of the Li Clan, succession is everything. If Jinshi is the Emperor's son, he is the primary heir. But if the world knows he was part of a baby-swapping scandal involving a consort who is no longer in power, his legitimacy is shot. Furthermore, the Empress Dowager's grief over her own lost child (the real little brother who died) is a political liability.
Jinshi hates the throne. He hates the "sparkles" he has to put on. He uses his position as a "eunuch" to escape the crushing weight of imperial expectations. By being a "brother" instead of a "son," he stays one step removed from the direct line of succession. It gives him freedom. Or at least, the illusion of it.
The Loulan and Shisui Connection
As the story progresses, the tree gets even more tangled. You start seeing how the great families—like the Shi clan—try to wedge themselves into the imperial bloodline. Loulan (or Shisui, depending on which persona she’s using) represents the external pressure on the Apothecary Diaries Jinshi family tree.
The Shi clan wanted to replace the current line. They wanted their own blood on the throne. This is why Jinshi's identity is so dangerous. If the Shi clan knew for a fact that the Emperor's "Little Brother" was actually a fertile heir, they would have doubled their efforts to either control him or kill him.
Maomao’s Place in the Web
Maomao isn't biologically related to Jinshi, thank goodness. That would make the romance... complicated.
However, her father, Lakan, is a high-ranking tactician. Her biological mother was a high-class courtesan. Maomao exists on the fringes of this royal drama, acting as the "fixer." She is the one who realizes that Jinshi’s physical features—specifically his resemblance to both the Emperor and Ah-Duo—are a dead giveaway.
She also realizes that Jinshi’s "allergic reaction" to certain foods and his specific physical traits are consistent with the Emperor's lineage. Maomao’s role isn't just to be a love interest; she is the curator of the truth in a world built on lies.
The Mystery of the Previous Emperor
We can't talk about Jinshi's family without mentioning the "Creepy Emperor"—the current Emperor's father. This man had a preference for... very young girls. It’s disgusting, and the series doesn't shy away from how much damage he did to the women in the Rear Palace.
The Empress Dowager was one of his victims.
This trauma trickles down. It’s why the current Emperor is so obsessed with having a healthy, functioning Rear Palace that actually treats women with some level of dignity. It's also why Jinshi's existence is such a miracle. He is a healthy male heir born out of a chaotic, abusive era.
The Physical Evidence
If you're looking for proof of the Apothecary Diaries Jinshi family tree beyond just dialogue, look at the character designs.
- The Eyes: Jinshi shares the same piercing, intelligent gaze as the Emperor.
- The Demeanor: He has Ah-Duo’s stoic grace when he’s not acting like a pampered prince.
- The Hair: That deep, dark hair is a hallmark of the imperial line.
Maomao notices that Jinshi uses a specific type of makeup and scent to hide his "masculinity" and to blur his resemblance to the Emperor. He is literally painting over his family tree every single morning.
What Happens if the Truth Comes Out?
If the public ever finds out that Jinshi is the son of Ah-Duo and the Emperor, everything changes.
First, the current "Crown Prince" (the infant son of Consort Gyokuyou) would have a rival. This would split the court into factions. Some would support Jinshi because he is older and "proven." Others would support Gyokuyou’s son because his mother is currently in favor.
Second, the Empress Dowager would be humiliated. Admitting that she raised a child that wasn't hers—and that her biological son died because of negligence—would destroy her standing.
Third, Jinshi would lose his ability to move freely. No more wandering the streets. No more helping Maomao solve crimes. He would be locked in a golden cage, forced to produce heirs and sign documents until he dies.
It’s no wonder he stays in the "eunuch" closet.
Why This Matters to You
Understanding the Apothecary Diaries Jinshi family tree isn't just about trivia. It’s about understanding why Jinshi acts the way he does.
He isn't just a "pretty boy" lead. He is a man living a double life to protect his mother’s secret and his father’s throne. Every time he flirts with Maomao, he is doing it with the knowledge that his bloodline makes him a target.
Next Steps for Fans:
- Watch for the Blue Roses: In the series, pay attention to the scenes involving the Emperor and Ah-Duo. The subtext is much louder once you know they are Jinshi's parents.
- Compare Character Models: Look at the Emperor’s face next to Jinshi’s in the manga or anime. The similarities are intentional.
- Read Volume 2 of the Light Novel: This is where the Ah-Duo/Jinshi connection is most explicitly explored through Maomao’s deductions.
The family tree of Jinshi is a masterpiece of hidden storytelling. It turns a standard palace drama into a high-stakes survival game where the biggest secret is written right on the protagonist's face.
