River’s relationship with the piano has always been fraught with the possibility of fear and failure. The final part of the novel sees River overcoming his fears by learning to use fearful situations to channel more positive and constructive feelings into the world, like love. This turn begins with the fire he witnesses from the Beijing Railway Station, as he watches ash fall from a fire in a migrant worker neighborhood and fears for his mother’s safety. This scare transforms his abstract longing into a concrete plan: He will win the World Chopin Competition to create a metaphorical “fire” big enough for his mother to see. Rather than fear the stage and all the past experiences he has had on it, River understands in this moment that moments of fear can easily be turned into moments of love by sheer force of will. This artistic purpose solidifies when he chooses his competition piano and evaluates it based on its ability to make the notes of his mother’s favorite piece, the Arabesque, linger in the air. This choice signals an important shift in his motivation; rather than play simply to win, he is taking the stage to tell his and his mother’s story. His culminating performance of Tchaikovsky’s Piano Concerto No. 1 becomes the ultimate expression of this purpose, described as a “home-calling, simple and destructive, a message meant for her” (311). The concerto, a piece that once represented the scale of his ambition, is re-conceived as an intimate narrative of their life, struggle, and bond, making his eventual victory a shared triumph.

The final part of the novel unfolds against the backdrop of China’s severe “zero-COVID” policy, which manifests as an impersonal, absolute force of state control that catalyzes the worst aspects of the country’s class divisions. While River’s privileged quarantine in a luxury compound allows him to focus entirely on his music, Song’s experience is one of constant exposure and physical decline. As a delivery worker, she is celebrated as a “hero” for keeping the city running, but this status is a thin veil for her disposability, a key aspect of The Invisible Labor of Migrant Workers. The narrative emphasizes this irony by juxtaposing the city’s suddenly clear “blue-blue sky” at the end of the novel, a result of the industrial shutdown, with the fatal illness developing in her lungs, in itself a direct consequence of years of exposure to pollution and physical strain. The state’s power is later embodied by the faceless “Big Whites” who drag River’s neighbor to quarantine and the plastic barricade that seals Song’s alley. This lockdown is the tragic culmination of the systemic obstacles she has faced throughout her life; the same state that marginalized her through the hukou system now physically imprisons her, making a public health crisis the final barrier between a dying mother and her son.

In a powerful reversal, the very technology that underpins the gig economy’s exploitation becomes a tool for community and salvation. Trapped by the lockdown, Song uses her delivery platform to send a city-wide call for help, transforming her work phone from an instrument of algorithmic pressure into a beacon of hope. This act mobilizes the city’s network of riders for a personal cause, culminating in the scene where a “neon wave” of workers in yellow uniforms blocks the road to deliver Song’s message to River. This moment makes a typically invisible workforce suddenly and powerfully visible, as workers atomized by the gig economy unite in an act of solidarity that momentarily overwhelms state authority. The motif of phones and QR codes, usually associated with commercial transactions and state surveillance, is re-appropriated to forge a deep human connection. The Monkey King, the rider who leads the charge, acts as a modern-day mythological guide, using his scooter to navigate the city’s gridlock and deliver a message of life and death, demonstrating how grassroots community can emerge from within a dehumanizing system.

The climactic breach of the lockdown is facilitated by an appeal to shared humanity that momentarily cracks the facade of state authority. The security guard, Smalls, initially an obstacle, is transformed into an ally through the universal language of art and family. When he recognizes River as “that pianist. That prodigy” (321), he ceases to be a simple enforcer of rules. His connection to River’s music through his piano-playing niece creates a personal link that transcends his official duty. Mini’s playful but pointed argument, invoking the niece’s admiration for her “future husband,” further collapses the distance between the guard’s role and his personal identity. Smalls’s decision to look the other way is a small but significant act of defiance, humanizing a system designed to be ruthlessly efficient. This interaction suggests that even within an oppressive state apparatus, individual empathy and personal connection can create openings for compassion, challenging the idea that such systems are monolithic.

The reunion between Song and River brings their journey full circle, offering a form of peace that transcends physical separation and even death. When River finally reaches his mother, his triumphant words, “We did it, Ma. We won” (326), affirm their shared struggle and victory. In her final days, their roles are lovingly reversed as he cares for her, feeding her sugar water just as she did for him as an infant. This act of care, along with his placement of the girl clothespin next to the boy on the windowsill, restores a sense of wholeness to their fractured family. The reunion of the clothespin dolls symbol, “back where they belong. Together” (327), provides a tangible image of their restored bond and brings the theme of The Relentlessness of Maternal Sacrifice to its moving conclusion. In the novel’s final moments, as River holds his dying mother, he rests his head on her chest and hears the music of her heartbeat, the first song he ever knew. Though their final encounter is brief, Song’s death is a transformation of their connection into something permanent, forever preserved in memory and the music that lives on within River.
