Cinder & Dr. Zhong

Lore & Background

In the stratified society of New Beijing, cyborgs are treated as second-class citizens at best and as threats at worst. Into this world, Dr. Zhong—a soft-spoken mechanic who mends engines and, more delicately, repairs the damaged bodies of those the system discards—takes in a young girl whose mother has died and whose artificial limbs mark her as dangerous in the eyes of the Red Guard. He does not hide her. He feeds her, teaches her, and lets her sit beside him in the garage while he works, treating her hands as capable and worthy rather than monstrous. Iko, his biological daughter, grows up alongside Cinder, and the three of them form a small, imperfect family that the rest of the city would consider a joke.

Dr. Zhong's world is one of oil, solder, and patience. He speaks softly, listens more than he lectures, and measures a person's worth by how they treat others rather than by their blood or their parts. For Cinder, who has spent her life being stared at, whispered about, and feared, his matter-of-fact kindness is a kind of revolution. He does not perform his love; he simply does the next small thing—fixes a broken joint, saves a plate of food, tucks a blanket around her shoulders. It is this unglamorous, daily devotion that makes his eventual loss so shattering to Cinder and so central to the novel's emotional engine.

His death, arriving suddenly and violently at the hands of the state's enforcers, transforms Cinder's grief into fuel. The gentle girl who once feared her own hands becomes someone who will burn kingdoms to the ground. In the books that follow, Cinder carries Dr. Zhong's voice in her memory—the way he'd hum while tightening bolts, the way he'd say her name like it was a small, precious thing. He is the measure of what the world took from her, and the standard by which she judges every choice she makes as a warrior, a diplomat, and eventually a queen.

In Their Own Story

The garage smelled of hot metal and the faint sweetness of solder flux. Outside, New Beijing's smog pressed against the windows like a grey hand, and the distant thrum of the Red Guard's patrol drones vibrated through the floor. Dr. Zhong set down his wrench, wiped his palms on a rag, and looked at the girl perched on the workbench, her artificial fingers tracing the edge of a half-finished engine block.

"You don't have to watch me work, Cinder," he said, not unkindly. "Go read. Go be young."

She shook her head. Her jaw worked. "I want to help. I want to be… useful."

He was quiet for a moment. Then he reached over and, with the same careful hands he used to rethread a cyborg's spinal wiring, he brushed a smudge of grease from her cheek. "You are," he said, simply. "You have always been."

She didn't cry. She never cried in front of him. But she stayed, and he handed her the small screwdriver, and together they finished the engine in the blue glow of the work lamp while the city grumbled and threatened beyond the glass. For an hour, the world was just the two of them, a bench, and the small, steady rhythm of making something broken whole again.

Reader's Guide

The bond between Cinder and Dr. Zhong is an adoptive father-daughter relationship built in the shadow of a city that despises her. He is her first and most enduring source of unconditional love; she is his reason for risking his safety in a society that punishes those who shelter cyborgs.

In Cinder, the relationship is the emotional core of the novel. Their domesticity—shared meals, his quiet repairs, her fierce protectiveness of his garage—stands in stark contrast to the political machinations of the Lunar palace. The turning point is his murder by the Red Guard, a violent severing that converts Cinder's grief into a cold, driving purpose. His death is the wound that never closes; it is the 'why' behind every act of violence she commits and every act of mercy she extends.

Across Scarlet, Cress, and Winter, Dr. Zhong is absent but omnipresent. Cinder's leadership style—her insistence on protecting the vulnerable, her distrust of authority, her insistence that cyborgs and humans are equal—echoes his values. Iko, in her own arc, carries the memory of the father who loved both girls equally. The relationship costs Cinder her childhood, her innocence, and the simple life she once wanted. It costs the story its gentlest voice. What it gives Cinder is a moral anchor: the knowledge that she was, once, simply a girl who helped her father fix a car, and that that girl still matters.

Did You Know?

• Dr. Zhong's garage is one of the few spaces in New Beijing where Cinder is treated as a person rather than a cyborg, making it a recurring symbol of the life the world tried to take from her.
• His profession as a mechanic who repairs cyborgs' bodies places him in a uniquely vulnerable position: he is both a skilled tradesman and a target, since the state views cyborg maintenance as a potential act of rebellion
• Cinder's relationship with Iko—her step-sister—is mediated entirely through Dr. Zhong's parenting, and his insistence on treating both girls as equals shapes Cinder's later advocacy for cyborg rights.
• Even after his death, Cinder's leadership philosophy in the later books mirrors his quiet, practical compassion: fix what's broken, protect the small, and don't let the powerful define your worth.
