The minister of crime of Ch'an asked whether the duke Chao knew propriety, and Confucius said, 'He knew propriety.'
Confucius having retired, the minister bowed to Wu-ma Ch'i to come forward, and said, 'I have heard that the superior man is not a partisan. May the superior man be a partisan also? The prince married a daughter of the house of Wu, of the same surname with himself, and called her,- "The elder Tsze of Wu." If the prince knew propriety, who does not know it?'
Wu-ma Ch'i reported these remarks, and the Master said, 'I am fortunate! If I have any errors, people are sure to know them.'
