However, it appeared that Yu Di did not exercise much actual chancellor responsibility, as, per the precedent of Du You, he only attended imperial meetings three times a month. Further, when he suggested to Emperor Xianzong that harsher punishments be instituted, Emperor Xianzong did not accept the proposal and further, in discussion with other chancellors, referred to Yu as being evil in submitting the proposal and wanting him to lose the hearts of the people.
