Feng Hong
It is not known when Feng Hong was born, but it is known that he was Feng Ba's younger brother. There was no historical record about him until 407, after his brother Feng Ba (along with another brother, Feng Sufu (馮素弗), as long as others) had overthrown the tyrannical Later Yan emperor Murong Xi and made Murong Xi's adoptive nephew Murong Yun emperor. (Murong Yun, who soon changed his name back to the original Gao Yun, is regarded by some as the last emperor of Later Yan and by some as the first emperor of Northern Yan.) Late in 407, Gao Yun commissioned Feng Hong as a major general. Probably also at the same time (but definitely during Gao Yun's reign), Feng Hong was created the Duke of Ji.
