不食周粟 (Bù shí Zhōu sù)

Basic Info

Chinese Idiom: 不食周粟 (Bù shí Zhōu sù)
Pinyin: bù shí Zhōu sù
Literal meaning: “Not eat Zhou’s millet/grain.”
(不 = not; 食 = eat; 周 = the Zhou Dynasty; 粟 = millet / grain / food)

It means to refuse to eat food that comes from the Zhou Dynasty.

Figurative Definition

It describes refusing to accept food, salary, benefits, or recognition from a ruler, government, or group that one considers illegitimate or morally unacceptable. It is a symbol of loyalty, moral integrity, and refusal to compromise one’s principles – even at the cost of personal suffering or death.

In modern usage, it can mean:

• Refusing to serve or cooperate with a regime one believes is unjust.
• Rejecting tainted money or benefits.
• Staying morally clean by not accepting help from a source one disapproves of.

It can be used positively, as praise for integrity, or critically, as an example of rigid, impractical purity.

Cultural & Historical Origin

The idiom comes from Sima Qian’s Records of the Grand Historian (《史记·伯夷列传》), in the biography of Bo Yi and Shu Qi (伯夷、叔齐).

Bo Yi and Shu Qi were two brothers, sons of the Lord of Guzhu. After the Zhou Dynasty overthrew the Shang Dynasty, they regarded the conquest as unjust and refused to recognize Zhou rule. They said:

“We will not eat the grain of Zhou.”
(义不食周粟。)

They withdrew to Mount Shouyang (首阳山), where they survived by eating wild ferns and herbs. Eventually, they starved to death rather than submit to the new dynasty.

Confucius and Mencius later praised Bo Yi as a “sage of purity” (圣之清者) – a man who would not compromise his moral standards for comfort or survival.

• Confucius said, “Boyi (Bo Yi) and Shuqi (Shu Qi) never bore old ills in mind and had but the faintest feelings of rancour. (The Analects Chapter 5.23);
• Confucius said, “They (Bo Yi and Shu Qi) were good men who lived in the days of old… They sought Goodness and got Goodness…” (The Analects chapter 7.15)
• Mencius said: “A sage is the teacher of a hundred generations; Boyi and Liuxia Hui are such men. Therefore, those who hear of Boyi’s noble character will become honest even if they were greedy, and the cowardly will resolve to stand firm….” (Mencius Chapter 14.15)
• Mencius said: “Bo Yi would not look at evil colors with his eyes, nor listen to evil sounds with his ears. He would not serve a ruler he did not approve of, nor command people he did not approve of. When the empire was well-governed, he would advance to serve; when it was in chaos, he would retreat…. Therefore, those who heard of Bo Yi’s style were made honest by his influence, and the cowardly were inspired to establish firm resolve.” (Mencius Chapter 10.1)

Key Lesson

Principles can demand a heavy price. The story of Bo Yi and Shu Qi asks us to consider how far we are willing to go for our beliefs. Is it better to compromise and live, or to remain pure and die? There is no easy answer. The idiom praises integrity, but it also warns that absolute purity can lead to isolation and self-destruction. Wisdom lies in knowing when to stand firm and when to engage with an imperfect world.

Cultural Note

In traditional Chinese culture, “不食周粟” was a powerful symbol of loyalty to a fallen dynasty and personal moral purity. It was often used to praise officials who refused to serve a new regime after a dynastic change.

In modern Chinese, the idiom is still used to describe someone who refuses to accept benefits from a source they consider illegitimate, though it can also carry a slightly critical tone – implying someone is too rigid or out of touch with reality.

Related images include “采薇” (picking ferns), which alludes to their exile, and “首阳山” (Mount Shouyang), a symbol of loyalist withdrawal.
