In 410, Feng Ba's cousin Feng Wani (馮萬泥) and another cousin's son Feng Ruchen (馮乳陳) both felt that they contributed much to Feng Ba's success, and therefore were resentful that they were not at Longcheng and in control of the imperial government but were required to serve as commanding generals at the cities of Feiru (肥如, in modern Qinhuangdao, Hebei) and Bailang (白狼, in modern Zhaoyang, Liaoning). They therefore rose in rebellion together. Feng Ba sent Feng Hong and Zhang Xing to attack them, and after 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.
