Doubles and Mistaken Identities

Doubles and Mistaken Identities is one of the book’s most consequential devices for turning resemblance into danger. A familiar face or a socially reassuring title can conceal a stranger, redirect desire, or make a genuine relationship appear false. The pattern reaches beyond simple confusion: it tests whether Su Xiangwan, Lu Xun, and those around them recognize one another through appearance, names, kinship, conduct, or accumulated trust. Again and again, the copy is persuasive until a voice, a remembered response, or an intimate bond exposes the difference.

Resemblance as a Weapon

The clearest instance occurs when Lu Xun explains that the woman before him looked and sounded exactly like Su Xiangwan. He says that he did not touch her and tried to restrain himself, but admits that the likeness nearly deceived him until she suddenly called his name. Her appearance and voice created the surface of identity; her failure to possess the right intimate recognition revealed the substitution. The scene therefore treats identity as more than a visual fact. Lu Xun’s knowledge of Su Xiangwan is measured by the small, decisive sign that an impostor cannot reproduce.

The attempted deception is also linked to drugging. Lu Xun states that he had been drugged but showed no reaction, and dismisses the method as unnecessary against him because he is immune to that kind of substance. He recalls being kidnapped at the age of twelve, when the kidnappers forced him to take various medicines and he nearly lost his life; the experience left him resistant to drugs. His childhood trauma thus becomes a practical defense against a later identity plot. What was once an assault on his body has become part of the knowledge that protects his judgment.

The Mo Brothers and the Unstable Face

The motif reappears through Mo Beichen and Mo Beiyu. When a doctor emerges from the Hospital ward, Lu Xun immediately becomes wary on seeing a man he takes to be Mo Beichen. The doctor, however, greets Su Xiangwan as Miss Su, and she identifies him as Mo Beichen’s brother, Mo Beiyu. The resemblance is close enough to trigger Lu Xun’s suspicion before the social facts have been explained, while the brothers’ different names and conduct restore the distinction.

Su Xiangwan’s own confusion is more intimate. After waking in an unfamiliar small bedroom, she becomes alarmed and mistakes Mo Beiyu for Mo Beichen. He corrects her by pointing out that Mo Beichen would not be dressed in casual clothes and identifies himself as Mo Beiyu. The correction depends on behavior and clothing rather than facial difference, because the face offers no reliable help. In this setting, a wardrobe detail becomes evidence of personhood.

The confusion deepens when Su Xiangwan remembers having once saved Mo Beichen. Mo Beiyu explains that his cousin found her unconscious by the roadside during morning practice, and that the cousin had cared for her for two days while Mo Beiyu happened to be staying at her home. Su Xiangwan says that she would have saved anyone, but describes Mo Beichen as arrogant and tyrannical, entirely unlike the humble and courteous man she encountered while he was injured. Looking at Mo Beiyu’s nearly identical face, she realizes that the injured man’s tone and manner had resembled Mo Beiyu, even though he had given his name as Mo Beichen. The brothers’ likeness transforms a past rescue into an unresolved question of who had actually stood before her.

Kinship Names and Desire

The concept also operates through labels that imply safety without guaranteeing blood relation. Shen Yiyun is described as Lu Xun’s uncle’s adopted child and therefore his cousin, and Lu Xun explains that he arranged nearby accommodation for her when she came to Cloud City to perform. The title of cousin places her inside a family structure, but the explanation does not erase Su Xiangwan’s unease. The narrative keeps the legal or adopted relationship beside the possibility of romantic suspicion, exposing how easily a kinship term can become a shield, a boundary, or a source of mistrust.

Chu Fei makes the boundary still more explicit when he compares the situation to a woman who wore the clothes of a close relative even though he had no blood relationship with her. He adds that he liked her greatly and consequently regarded Lu Xun as an eyesore. His statement separates costume and kinship from desire: a relative-like appearance may suggest prohibition, but the absence of blood relation leaves the social meaning unstable. Chu Fei insists that he does not force women and prefers the process of pursuit, making the chase itself another form of identity pressure. The woman is positioned between family resemblance and romantic object, while Lu Xun is forced to confront the threat beneath the reassuring vocabulary of kinship.

Su Xiangwan’s response to Lu Xun demonstrates the opposite movement, from uncertainty back to marital recognition. When he asks what their relationship is, she calls him her husband while pulling off his shirt flirtatiously. Lu Xun remains unsure whether she truly knows who he is, because the same answer could theoretically be given to any man in the surrounding company. Her declaration carries emotional force, but the scene preserves the problem of recognition: a title such as husband is meaningful only when attached to the particular person and history it names.

Recognition Beyond Appearance

Across these episodes, the book contrasts resemblance with reliable identity. Lu Xun distinguishes the disguised woman through her inability to call his name correctly at the crucial moment. Su Xiangwan distinguishes Mo Beiyu from Mo Beichen through clothing, manner, and later recollection. Mo Beiyu’s account of the roadside rescue supplies a history that the face alone cannot provide. These clues make identity cumulative rather than instantaneous: a person becomes recognizable through actions, speech, bodily responses, and remembered circumstance.

The recurring substitutions also redistribute power. A false likeness can approach Lu Xun under the protection of Su Xiangwan’s appearance, while a shared face can make Su Xiangwan vulnerable to confusion when she is weak and unable to move. At the same time, resemblance creates unexpected continuities. The courteous behavior of the injured Mo Beichen resembles Mo Beiyu so strongly that the brothers seem to exchange not only faces but temporary manners. The result is not merely comic confusion; it unsettles the assumption that character is transparently written on the body.

Narrative Significance

Doubles and Mistaken Identities binds together the book’s plots of marriage, pursuit, rescue, jealousy, and family obligation. It exposes the fragility of relationships built on names and appearances, especially when adopted kinship, cousinhood, marriage, and romantic pursuit occupy the same social space. The device repeatedly asks whether people are recognized as themselves or merely accepted as the role their face appears to authorize.

Yet the motif does not conclude that identity is unknowable. Instead, it makes recognition an ethical practice. Lu Xun’s resistance to the drugged substitute depends on knowledge earned through trauma and intimacy; Su Xiangwan’s understanding of the Mo brothers develops through conduct and memory; and the marital claim between Su Xiangwan and Lu Xun must be tested against the possibility that the wrong person stands before either of them. In this world, likeness can open the door, but only history, behavior, and reciprocal knowledge can keep identity from collapsing into a mask.
