they were defeated by Feng Hong and Zhang, they surrendered, but Feng Hong executed them regardless. After this incident, Feng Ba created him the Duke of Zhongshan. Little is known about Feng Hong's actions during most of Feng Ba's reign, other than that he appeared to have remained in powerful positions, and by 430 he was Feng Ba's prime minister. That year, Feng Ba was seriously ill, and he issued an edict transferring his authorities to his crown prince Feng Yi (馮翼). However, Feng Ba's favorite concubine Consort Song wanted to have her son Feng Shouju (馮受居) inherit the throne, and therefore told Feng Yi that Feng Ba would soon recover and that he should not be so anxious to take over authority; Feng Yi agreed and retreated to his palace.

However, in 431, Feng Hong created Lady Murong princess instead, and in 432, he created Princess Murong's son Feng Wangren (馮王仁) crown prince. In fall 432, Northern Wei's
