One Centimetre

Tao Ying's struggle to maintain her moral image and her son's trust after a false accusation of cheating at a temple gate.

  1. The Dual Persona of Tao Ying

    Tao Ying balances her practical survival instincts with the desire to be a perfect role model for her son.

    • Practical Survivalist — When alone, she avoids bus tickets to save money and 'punish' careless conductors.
    • The Flawless Mother — In Xiao Ye's presence, she suppresses her instincts to set a cultured, moral example.
  2. The Bus Incident

    A routine trip establishes the value of self-esteem over financial savings.

    • Purchasing Self-Esteem — She buys a ticket for Xiao Ye despite him being under the limit to validate his pride.
    • Refusal to Lie — She refuses to claim the fare back from work to avoid setting a dishonest example.
  3. The Temple Conflict

    A confrontation with a guard leads to a public accusation of dishonesty.

    • The 'Earthworm' Mark — A flawed red line on the wall used by the guard to claim Xiao Ye is over the height limit.
    • Public Humiliation — The crowd jeers at Tao Ying, questioning her motherhood and integrity.
  4. The Erosion of Trust

    External factors and a physical blow cause Xiao Ye to doubt his mother.

    • The First Blow — Tao Ying hits Xiao Ye's head to smooth his hair, traumatizing him and appearing guilty.
    • Flattering Scales — A vendor's inaccurate scale makes Xiao Ye seem taller, confirming his suspicion of her.
  5. The Quest for Vindication

    Tao Ying seeks to prove her innocence to 'melt the ice' in her son's eyes.

    • The Letter of Truth — She writes to the temple administration to demand a fair measurement and correction.
    • Moral Restoration — She rejects money and free tickets, wanting only for officials to tell Xiao Ye she was right.
  6. Literary Imagery

    Bi Shu-min uses vivid figures of speech to highlight emotional states.

    • Ice in His Eyes — A metaphor representing the coldness and lack of trust Xiao Ye feels for his mother.
    • Trembling Pei-pa Strings — A simile describing Tao Ying's hands to show her extreme agitation and fear.

Chapter notes

An exploration of Bi Shu-min's short story about Tao Ying, a mother whose commitment to setting a moral example for her son leads to a conflict over a single centimetre of height and the pursuit of truth.

Introduction to Tao Ying

The story introduces Tao Ying, a hardworking mother and canteen cook, whose approach to life is defined by a mix of practical survival and a desire for grace.

Tao Ying works in a factory canteen, baking wheat cakes over an open fire. Her life is one of physical labor and careful budgeting. When traveling alone on the bus, she often avoids buying a ticket if the conductor appears 'casual and careless.' She views this not as a crime, but as a small personal saving and a 'punishment' for the conductor's lack of diligence.

However, her behavior changes significantly when she is with her young son, Xiao Ye. In his presence, she strives to be a 'perfect, flawless mother.' She recognizes that to him, she is the 'centre of the universe,' and she feels a profound responsibility to set a moral and cultured example, even if it contradicts her own survival instincts.

The Bus Incident: Buying Self-Esteem

A routine bus ride becomes a lesson in parental integrity when Xiao Ye insists on the ritual of having a ticket.

On the bus, Xiao Ye is eager to have a ticket, as children often value the 'ritual' of the ride. Although a painted mark on the door indicates the height requirement is 1.10 m, Tao Ying tells him he is 'still one centimetre away' from the mark. The conductor confirms that the child is one centimetre short of requiring a ticket. Tao Ying initially considers saving the twenty cents, which could buy several days' worth of vegetables.

Ultimately, she decides to buy two tickets. The author notes that 'to be able to purchase self-esteem with twenty cents' is a rare opportunity. Tao Ying chooses to validate her son's sense of pride and maturity over financial saving. She also refuses to claim the ticket fare back from her workplace later, as she refuses to lie or set a dishonest example for her observant son.

The Temple Conflict

The central conflict of the story arises at a temple gate, where a guard challenges Xiao Ye's height.

Tao Ying takes Xiao Ye to a large temple using a complimentary ticket. At the gate, a young guard in a red uniform stops them, insisting that Xiao Ye is over the 110 cm limit and needs his own ticket. Tao Ying, confident that her son is still under the limit based on their bus ride, politely disagrees.

The situation escalates as a crowd gathers. The guard points to a red line on the wall—described as an 'earthworm'—and claims Xiao Ye ran past it. When Xiao Ye stands against the mark, the line appears to be at the level of his ear, suggesting he is significantly over the limit. This discrepancy shocks Tao Ying and turns the crowd against her.

The Moment of Betrayal

Under pressure from a jeering crowd and a mocking guard, Tao Ying reacts in a way that damages her relationship with her son.

Frustrated and confused by the measurement, Tao Ying hits Xiao Ye on the head to smooth down his hair, hoping he will appear shorter. The crowd reacts with hostility, accusing her of being a 'disgrace' and suggesting she isn't his 'natural mother.' The guard mocks her further, citing the 'International Standard Ruler' in Paris to assert his authority.

Xiao Ye is traumatized, not just by the physical blow—the first he has ever received—but by the realization that his mother is being accused of dishonesty. Tao Ying realizes that if she buys the ticket now, she will be admitting to a 'crime' she didn't commit, but if she doesn't, she cannot enter. She chooses to leave, but the damage to Xiao Ye's trust is already done.

The Flattering Scales

A secondary measurement by a street vendor adds to the confusion and deepens Xiao Ye's suspicion.

After leaving the temple, Xiao Ye uses his own money to be measured by an old woman with a height scale. The scale reads 'one metre eleven.' Xiao Ye, now convinced his mother was trying to cheat the temple, runs away from her in tears. He begins to look at her 'as if mother has turned into a big bad wolf.'

Tao Ying later discovers the truth: the old woman's scales are 'flattering scales,' intentionally adjusted to make people seem taller and lighter to make them happy. However, Xiao Ye is too young to understand this 'convoluted logic.' To him, the temple guard and the street vendor were right, and his mother was wrong.

The Pursuit of Truth

Determined to regain her son's trust, Tao Ying seeks an official correction of the measurement.

Tao Ying's work suffers as she becomes distracted by the 'ice' in her son's eyes. She measures him carefully at home while he sleeps and confirms he is 1.09 m. To prove her innocence, she decides to write a letter to the temple administration.

She enlists the help of a colleague known as 'the Writer' to make her letter more 'moving.' The Writer suggests using a dramatic opening about the 'infinite power of the Buddha' making a boy grow and shrink. Though she cannot remember all his flowery words, she sends a corrected version of the letter, hoping for a response that will vindicate her in front of Xiao Ye.

Vindication and Resolution

The story concludes with a visit from temple officials who provide the truth Tao Ying desperately needs.

Two elderly officials eventually visit Tao Ying's home. They measure Xiao Ye with a professional metallic tape and find him to be 'one metre ten, just so.' Tao Ying points out that a month and nine days have passed since the incident, meaning he was certainly shorter than the limit during the temple visit. The officials cannot refute this logic.

The officials admit that before leaving the temple, they checked the 'earthworm' mark and realized it was not drawn accurately. They offer Tao Ying five dollars or two free tickets as compensation. Tao Ying refuses both, as she doesn't want money or a return to a place of 'unhappy memories.' Instead, she asks the officials to explain to Xiao Ye that his mother did nothing wrong, restoring her integrity in his eyes.

Literary Devices and Language

Bi Shu-min uses vivid imagery and figures of speech to convey the emotional depth of the characters.

The author employs similes to describe Tao Ying's physical and emotional states, such as her jacket 'ballooning up like a tent' or her hands trembling 'like the strings on a pei-pa.' These comparisons help the reader visualize her agitation and the high stakes of her social performance.

Metaphors are also used effectively, notably the 'ice in her son's eyes' to represent his coldness and lack of trust. The 'earthworm' on the wall serves as a metaphor for a flawed and shifting standard of justice. The story also highlights the importance of word stress in English, noting how words like 'object' or 'conduct' change meaning between noun and verb forms.
