Basic Info

Chinese Idio: 智子疑邻
Pinyin: zhì zǐ yí lín
Literal Meaning: Think one’s own son is clever yet suspect the innocent neighbor.
Figurative Meaning: Judge things with personal bias instead of objective facts; favor family while unfairly suspecting outsiders facing identical clues.

Cultural Background

This fable comes from Han Feizi, a prominent legalist classic of the Warring States Period. It is a cautionary idiom criticizing subjective prejudice and double standards. People often let kinship and personal feelings distort rational judgment, leading to unfair suspicion of irrelevant people.

Original Story & English Translation

A wealthy man’s courtyard wall was damaged by heavy rain. His son warned: “Fix the wall quickly, or thieves will break in.” An elderly neighbor also gave the identical reminder to repair the broken wall.

That very night, burglars stole valuables from his house. The rich man praised his son for being foresighted and wise, yet grew suspicious that the elderly neighbor was the real thief who committed the robbery.

Usage

Derogatory usage. Used to criticize biased reasoning: reaching different verdicts for identical advice only because of different personal relationships.

Key Lesson

A good warning is a good warning, no matter who says it. Do not judge advice – or suspicion – by the person giving it. Judge it by the evidence. The idiom criticizes both blind trust in loved ones and blind suspicion of strangers.

Cultural Note

Unlike many Chinese idioms that praise strategy or warn against enemies, “智子疑邻” is about fairness, objectivity, and self‑awareness. It is often quoted in discussions of justice, management, and interpersonal relationships – reminding people to overcome emotional bias when making judgments.

Opposite Mindset (for contrast)

“对事不对人” (Duì shì bù duì rén) — “Judge the matter, not the person.” This is the fair, objective ideal that “智子疑邻” warns us to practice.
