In 451, there would be further political turmoil, with Crown Prince Huang and his associates being the victims. Crown Prince Huang had been considered able and all-seeing, but overly trusting of his associates, while privately managing farms and orchards and receiving profits from them. Crown Prince Huang greatly disliked the eunuch Zong Ai, and Zong decided to act first, accusing Crown Prince Huang's associates Chou'ni Daosheng (仇泥道盛) and Ren Pingcheng (任平城) of crimes, and Chou'ni and Ren were executed. Further, many other associates of Crown Prince Huang were dragged into the incident and executed. Crown Prince Huang himself grew ill in anxiety, and died in summer 451. Soon, however, Emperor Taiwu found out that Crown Prince Huang was not guilty, and became heavily regretful of his actions in pursuing the crown prince's associates. He did not create a new crown prince, although he briefly created Crown Prince Huang's son Tuoba Jun the Prince of Gaoyang—but then cancelled that creation, figuring that the heir of the crown prince should not be created a mere imperial prince, suggesting that he intended for Tuoba Jun to inherit the throne.
