Northern Yan
In winter 432, the Northern Yan emperor Feng Hong's son Feng Chong (馮崇), who had feared that his father would put him to death because of false accusations by his stepmother Princess Murong, surrendered the important Northern Yan city of Liaoxi (遼西, in modern Tangshan, Hebei) to Northern Wei. To reward Feng Chong, Emperor Taiwu not only sent his brother Tuoba Jian (拓拔健) the Prince of Yongchang to save Feng Chong from his father's siege, but created him the Prince of Liaoxi with 10 commanderies as his fief.
