Song Yuner's Assault by a Client is a decisive turning point in the intertwined personal, social, and power conflicts surrounding Song Yuner, Lin Yanche, and Lu Xun. The assault is committed by a client introduced by Lin Yanche, and the client is identified as Mo Beichen, a powerful figure who had already tried to force Su Xiangwan into becoming his mistress despite her having saved his life. What first appears as a private crime therefore becomes a crisis involving professional mediation, coercive desire, and the circulation of protection through elite relationships.

Causes and Background

The event emerges from the entertainment-industry relationship between Song Yuner and Lin Yanche. Lu Xun tells Su Xiangwan that Song Yuner was assaulted by a client Lin Yanche had introduced to her. Su Xiangwan reacts with disbelief, asking how such a thing could have happened and who would have dared to commit it. The answer is not an anonymous local customer but Mo Beichen, a man who frequently travels in and out of Cloud City and possesses enough influence to act with apparent impunity.

Mo Beichen's prior conduct gives the assault its broader significance. Su Xiangwan had saved his life, yet he repaid that kindness by insisting that she become his mistress. His willingness to convert gratitude into an entitlement to possess her establishes a pattern of coercive power rather than an isolated lapse of judgment. Against that background, the assault on Song Yuner shows how women connected to the entertainment world can be exposed to men who treat access, influence, and personal desire as interchangeable forms of authority.

The event also links Song Yuner's vulnerability to Lin Yanche's position. Lin Yanche is not described as the assailant, but he is the person who introduced the client. That connection places him under moral and emotional pressure and gives Lu Xun a reason to intervene. The assault thus creates responsibility through a chain of introduction: Mo Beichen commits the violence, Lin Yanche's professional connection makes the encounter possible, and Lu Xun treats the resulting danger as a matter requiring action.

Discovery and Immediate Response

Lu Xun reveals the assault to Su Xiangwan while warning her that she cannot continue relying on him if she chooses to remain angry with him. His revelation abruptly changes the emotional direction of the conversation. Su Xiangwan realizes that something has happened to Song Yuner, and the news displaces the immediate quarrel between her and Lu Xun. The disclosure is therefore both an act of information and a reordering of loyalties: Song Yuner's injury becomes impossible to ignore.

Su Xiangwan identifies Mo Beichen as the likely client after Lu Xun explains that the man is someone she knows who is not local but often comes to Cloud City. Her recognition is grounded in Mo Beichen's earlier pursuit of her and in the danger already visible in his behavior. The connection makes the assault legible as part of a larger pattern in which Mo Beichen disregards a woman's refusal and treats personal claims as permissions.

Lu Xun's response is not limited to private sympathy. In a later call with Lin Yanche, he makes clear that he is angry because Lin Yanche has held Song Yuner too tightly in an unstable relationship while failing to protect her from the consequences of the client connection. Lu Xun taunts Lin Yanche over how easily Song Yuner can be coaxed back into his embrace, then warns him that if he fails Song Yuner again, Lu Xun will not remain merciful. The language is jealous and sarcastic, but the threat also establishes a protective boundary around Song Yuner.

Relationships and Power After the Assault

The assault intensifies the already complicated relation between Song Yuner and Lin Yanche. Song Yuner is caught between dependence, emotional attachment, and the danger associated with Lin Yanche's world. Lu Xun's accusation that Lin Yanche is holding her too tightly presents their relationship as potentially protective and possessive at the same time. Lin Yanche's introduction of the client makes him part of the causal chain leading to the assault, while his continued emotional hold over Song Yuner prevents the aftermath from becoming simple separation.

Lu Xun's intervention also affects his marriage to Su Xiangwan. His anger toward Lin Yanche is not detached public justice; it is entangled with jealousy, loyalty, and his determination to control threats surrounding the woman he calls his wife. When negotiating over East District land, Lu Xun makes his condition clear: if Lin Yanche wants Song Yuner to leave Lu Xun's affairs with Su Xiangwan alone, Lin Yanche must stop interfering in Lu Xun's relationship with Su Xiangwan. Lu Xun uses a major commercial asset to force a personal boundary, demonstrating that business resources and intimate protection operate through the same power structure.

The event also illuminates the contrast between formal kinship and actual desire. Shen Yiyun is described as the adopted child of Lu Xun's uncle and therefore Lu Xun's cousin, although they are not blood relatives. Lu Xun later dismisses the idea that a nominal relative should automatically be treated as a harmless intimate connection. His insistence that a non-blood relative may still be a man or woman, rather than an uncomplicated cousin, echoes the book's recurring suspicion of labels that conceal desire and risk. In this network, titles such as client, cousin, fiancé, and husband do not settle the ethical meaning of a relationship; conduct does.

Trauma, Care, and Recurring Violence

Song Yuner's assault belongs to a wider pattern in which violence returns through bodies, memories, and protective gestures. Lu Xun recalls that he was kidnapped at the age of twelve, drugged by his kidnappers, and nearly killed; afterward, he became resistant to drugs. The memory is described as an old pain that he can recount with an unwavering gaze, but it remains part of the reason he reacts intensely when coercion and bodily danger appear around him.

Su Xiangwan carries a different traumatic memory: her mother, suffering from a terminal illness and fearing that she would implicate the family, walked onto a balcony after seeing a drawing of Su Xiangwan's parents holding her hand. Su Xiangwan remembers the scene even though her grandfather believed she was too young to remember it. The assault on Song Yuner therefore enters a narrative already shaped by sexual danger, attempted self-destruction, kidnapping, and the fear of losing a loved one. The story repeatedly joins psychological shock to physical symptoms rather than treating violence as an event that ends when the immediate scene ends.

This pattern is visible in Su Xiangwan's later collapse. After leaving a confrontation, she becomes weak, feverish, and increasingly unconscious before fainting at the elevator. In another scene, Lu Xun returns with hot milk and finds her frightened and vacant; he holds her and assures her that he has been there all along. The care is intimate and calming, but it also belongs to Lu Xun's broader pattern of protective control. The book consequently presents safety as something urgently needed and yet never entirely free from possession.

Consequences and Narrative Significance

The assault changes the stakes of Song Yuner's connection with Lin Yanche and gives Lu Xun a direct reason to confront the people around her. It transforms a client introduction into a source of liability, makes Lin Yanche answerable for the environment he helped create, and turns Mo Beichen from an intrusive pursuer of Su Xiangwan into a demonstrated threat to another woman. The event also explains why Lu Xun's warnings toward Lin Yanche carry more force than ordinary rivalry.

Its consequences extend beyond Cloud City. Lu Xun and Lin Yanche later fly directly to Yan City, where Chu Fei's men are already waiting at the airport. The encounter reveals that their conflict has expanded from personal disputes into organized confrontation, with both men carrying enough people to guard against danger. Chu Fei openly tells Lu Xun that he is an eyesore because Chu Fei likes Su Xiangwan, while claiming that he prefers the process of pursuit and will not force a woman. His stated restraint throws Mo Beichen's coercion into sharper relief: the narrative distinguishes pursuit from assault, even as both are embedded in a competitive masculine economy around women's choices.

The event's strongest significance lies in this contrast. Song Yuner's suffering is not merely a device for making men fight. It exposes the failure of the social arrangements that place her in reach of a client, the possessive logic that treats women as prizes or obligations, and the uneasy forms of care that arise afterward. Lu Xun protects, threatens, negotiates, and disciplines; Lin Yanche is implicated through his introduction and challenged over his treatment of Song Yuner; Mo Beichen is revealed as a man whose entitlement can become violence. The assault therefore becomes a central test of whether relationships will be defined by ownership and repayment or by recognition of another person's refusal and vulnerability.
