Ran Qiu professed little interest in Confucian rituals, and his ambition was in the administration of a state. Confucius thought he lacked the virtue of ren or humaneness, and severely criticized him for failing to prevent Ji Kangzi from attacking Zhuanyu (顓臾), a vassal state of Lu, and for helping the Jisun household accumulate massive amounts of wealth. So severe was Ran Qiu's violation of core Confucian values, that Confucius suggested that he no longer considered Ran his disciple.
