After Grand Empress Dowager Feng re-assumed regency, she was said to be more dictatorial than she was before, but intelligent in her decisions and frugal in her living. Not only was she highly literate, but she also was capable in mathematics. However, she trusted several eunuchs and permitted them to interfere in governmental matters. Further, she greatly promoted her lovers Wang Rui (王叡) and Li Chong (李沖) -- both of whom were apparently talented officials, but whose promotions were beyond what their talents and contributions called for. She balanced her reputation by also promoting some honored officials who were not her lovers. Because she was concerned that she would be criticized for what was seen as immoral conduct, she punished those whom she perceived to be criticizing her or parodying her behavior with severe punishment, including death. One of her victims was Li Xin, who had contributed to her prior lover Li Yi's death, as she had Li Xin put to death in 477. Fearful that Emperor Xiaowen's mother's clan would try to take power, she falsely accused his grandfather Li Hui (李惠) the Prince of Nan Commandery of treason in 478 and had him and his clan slaughtered. She apparently accelerated the policy of Sinicization, which included social stratification, as she issued an edict in 478 requiring people to marry in their social classes.
