Feng Ba
In spring 434, Feng Hong sent messengers to Northern Wei to request peaceful relations. Emperor Taiwu refused. However, three months later, after Feng Hong submitted a petition (i.e., agreeing to be a vassal) denouncing himself and pleading for peace, and further offering a daughter to be Emperor Taiwu's concubine, Emperor Taiwu agreed—on condition that Feng Hong send Feng Wangren to visit him at the Northern Wei capital Pingcheng (平城, in modern Datong, Shanxi). Feng Hong also sent the Northern Wei messenger Huniuyu Shimen (忽忸于什門), whom Emperor Taiwu's father Emperor Mingyuan of Northern Wei had sent to Feng Ba in 414 but who then was detained by Feng Ba, back to Northern Wei.
