Feng Hong
Around the new year 433, Feng Lang and Feng Miao, believing that Northern Yan was on the verge of destruction and believing that Princess Murong was planning to have them killed, fled to Liaoxi (遼西, in modern Tangshan, Hebei), where Feng Hong had sent their older brother Feng Chong to be the commanding general of. They persuaded Feng Chong to surrender to Northern Wei, and Feng Chong sent Feng Miao to Northern Wei to offer his allegiance. Feng Hong, in response, sent his general Feng Yu (封羽) to put Liaoxi under siege. In spring 433, Emperor Taiwu sent his younger brother Tuoba Jian (拓拔健) the Prince of Yongchang to relieve Liaoxi, and further created Feng Chong the Prince of Liaoxi with a number of other honors, to try to encourage other defectors. Tuoba Jian's forces soon surrounded Feng Yu and forced his surrender, and then withdrew with 3,000 captive households. Feng Chong then requested permission to go to Helong to persuade Feng Hong to surrender, but Emperor Taiwu did not grant such permission.
