Duke Chu of Wei (衛出公) only became the ruler of the state because his father, the former crown prince Ji Kuaikui (姬蒯瞶), had been forced to flee the state after failing in an attempt to kill Nanzi (南子), the notorious consort of his father, Duke Ling (衛靈公), in 499 BCE.
After assuming the throne when Duke Ling died in 492 BCE, Duke Chu refused to allow his father to go back to Wei to pay his respects to the deceased Duke Ling, no doubt out of concerns that his legitimacy would be challenged. Not surprisingly, Kuaikui was less than delighted at this state of affairs and spent over a decade plotting a triumphant return to his homeland.
In 480 BC, Kuaikui saw his opportunity when he found out that Hun Liangfu (渾良夫), a bondservant of Kong Wenzi (孔文子), a deceased noble, was having an affair with Kong’s widow, Boji (伯姬).
Boji was also Kuaikui’s eldest sister, and he promised to pardon Hun and make him a high official if he would help him gain power. After succeeding in entering the capital of Wei, Kuaikui hid in the garden of his sister’s mansion while she persuaded her son, Kong Kui (孔悝), to join her in an alliance with her brother to overthrow his son. When Duke Chu heard about the plot he made his escape to the state of Lu, while Kong Kui proclaimed Kuaikui as Duke Zhuang of Wei (衛莊公).
For all his scheming, Kuaikui only managed to stay in power for a couple of years, before being sent into exile once again in 478 BCE.
Duke Chu’s personal name was Ji Zhe (姬輒). In the Analects, he is simply referred to as the Duke of Wei (衛君). Confucius was drawn into the struggle between father and son when he visited the state of Wei. Wisely, he didn’t allow himself to get directly involved, though his comments in Chapter 14 of Book 7 suggest that he thought that Duke Chu should cede the throne to his father.
Ran Qiu said: “Does the Master support the Duke of Wei?” Zigong said: “Well, I’m going to ask him.” Zigong went in and asked Confucius: “What sort of people were Boyi and Shuqi?” “They were virtuous men of old.” “Did they complain?” “They sought goodness and attained goodness. Why should they have complained?” Zigong left and said to Ran Qiu: “The Master does not support the Duke of Wei.”
Zilu asked: “If the Duke of Wei were to entrust you with the government of his state, what would be your first priority?” Confucius said: “It most definitely would be to rectify the names.” Zilu said: “Really? Isn’t that a little strange? How would that make things right?” Confucius said: “How dense can you get! If a leader doesn’t understand what they’re talking about, they should remain silent. If the names aren’t correct, language doesn’t accord with the truth of things. When language doesn’t accord with the truth of things, nothing can be carried out successfully. When nothing can be carried out successfully, ritual and music won’t flourish. When ritual and music don’t flourish, punishments and penalties miss their mark. When punishments and penalties miss their mark, the people don’t know where to place their hands and feet. Therefore, a leader must be able to give the appropriate name to whatever they want to talk about, and must also make sure they do exactly as they say. When it comes to speaking, a leader doesn’t allow any carelessness.”
