One Centimetre Story Movement in the NCERT PDF

The story moves from a bus ride to a larger question about fairness. Tao Ying first wants Xiao Ye to learn honesty, so she pays attention to the ticket rule even when money is tight.
The conflict grows because public officials treat the measuring rod as final truth and ignore the child's embarrassment. Tao Ying's complaint is not about money alone. It is about restoring Xiao Ye's faith in what she has taught him.
- Bus ride: Tao Ying measures Xiao Ye against the ticket rule.
- Public doubt: the conductor questions the one centimetre difference.
- Temple visit: another measurement turns the issue into a deeper insult.
- Complaint: Tao Ying writes clearly instead of accepting silent humiliation.
- Apology: the mistake is accepted, but the emotional wound remains important.
Tao Ying and the Bus Conductor Compared

Tao Ying and the conductor both deal with rules, but they use them differently. Tao Ying wants the rule to teach Xiao Ye honesty. The conductor uses the rule without seeing the child's hurt.
Good answers should compare moral intention with mechanical authority. Tao Ying's anger comes from public insult, not from the fare itself. This contrast makes the title meaningful for exam answers.
| Point | Tao Ying | Bus conductor |
|---|---|---|
| View of rule | Uses it to teach Xiao Ye honesty | Applies it without sympathy |
| Main concern | Her son's self-respect and moral growth | Public compliance with the fare rule |
| Effect | Turns humiliation into a written fight for fairness | Turns a small measure into a public insult |
How to Use the Chapter 5 Book PDF for Revision
Use the PDF in three rounds. First, read the full story without stopping. Second, mark each place where Tao Ying explains, defends or questions a rule. Third, connect those moments with Xiao Ye's response.
- For title answers: explain one centimetre as a small measure with large emotional weight.
- For character answers: compare Tao Ying's careful morality with public indifference.
- For theme answers: write about dignity, motherhood, arbitrary rules and trust.
- For textual support: use the official PDF before adding examples to answers.
