他山之石

1. Basic Information

• Pinyin: tā shān zhī shí
• English Translation: Stones from other mountains (learning from others' experience)
• Idiom Composition: 「他」（Other or another）＋「山」（Mountain）＋「之」（A particle indicating possession, similar to 'of'）＋「石」（Stone (specifically a whetstone used for polishing jade in this context)）
• Meaning: Literally, stones from another mountain that can be used as whetstones to polish one's own jade. Figuratively, it refers to the idea that the opinions, experiences, or even the mistakes of others can serve as a valuable reference for one's own self-improvement.

2. Detailed Meaning and Nuances

「他山之石」 contains the following nuances:

• Learning from the Outside: The idiom highlights the importance of not being insular. It suggests that external entities—whether they are other countries, companies, or individuals—possess knowledge that can facilitate one's own growth.
• The Metaphor of Jade and Stone: The idiom is often part of the full phrase 他山之石，可以攻玉 (tā shān zhī shí, kě yǐ gōng yù). Here, the 'stone' represents raw external input, and the 'jade' represents one's own character or work that needs refining. Even a 'rough stone' from elsewhere can help polish a 'precious jade' to perfection.

3. Usage

「他山之石」 is mainly used in the following contexts:

• Business and Technology: Used when discussing the adoption of advanced foreign technology or management methods to help domestic development.

4. Cultural Background and Notes

• The idiom originates from the Book of Songs (诗经), the oldest existing collection of Chinese poetry, specifically from the poem 'He Ming' (鹤鸣) in the 'Minor Court Hymns' (小雅).
• In the original text, 'cuo' (错) and 'gong' (攻) both refer to the act of grinding or polishing jade. This reflects an ancient Chinese value of humility and the proactive pursuit of self-improvement through external observation.
• While it can be used to mean learning from someone's mistakes (a 'counter-example'), modern Chinese usage leans heavily toward a positive interpretation: actively seeking out and adopting the strengths of others.
