Yan Ying's Admonition: "Dear Artificial Feet, Cheap Shoes"

In the State of Qi during the Spring and Autumn Period, Duke Jing frequently imposed the brutal punishment of yuexing (cutting off feet) for various offences, leaving the country filled with mutilated persons. Prime Minister Yan Ying observed a telling economic anomaly: in the market, artificial feet (yong) were sold at high prices while ordinary shoes (ju) were extremely cheap. When Duke Jing casually inquired about market conditions, Yan Ying seized the moment and replied, "Artificial feet are dear, shoes are cheap." This succinct remark starkly exposed how the excessive use of foot amputation had created a huge demand for prosthetics and depressed the demand for footwear. The indirect yet powerful metaphor shocked the Duke, making him realize the hidden brutality of his penal policies. Deeply moved, Duke Jing heeded the remonstration and decided to substantially reduce the application of such mutilating punishments, turning toward more lenient governance. Recorded in the Zuo Zhuan, this episode became a classic paradigm of moral persuasion in law.

There was no formal trial; after Yan Ying's metaphorical remonstration, Duke Jing of Qi acknowledged the cruelty of his policies and ordered a significant curtailment of foot-amputation and other harsh penalties, adopting a more merciful approach to punishment.

Whether the widespread and indiscriminate use of mutilating punishment (yuexing) was just and effective in maintaining social order, or whether its excessive cruelty not only caused unnecessary suffering but also eroded the ruler's moral legitimacy. The core conflict lay between unrestrained harsh legalism and benevolent, proportional governance.

The saying "dear artificial feet, cheap shoes" evolved into a lasting idiom and a moral caution against tyrannical cruelty. The case profoundly influenced Confucian and legal thought, championing proportionality and humanity in criminal justice. It served as a historical reference for later penal reforms, encouraging rulers to govern through virtue rather than terror, and remains a powerful anecdote in Chinese legal culture.
