馮弘
In 436, Feng Hong sent another embassy, offering to send Feng Wangren as a hostage. Emperor Taiwu, not believing in Feng Hong's offer, refused, and prepared a final assault. When he arrived at Helong, however, Feng Hong had already requested assistance from Goguryeo, which sent troops to assist Feng Hong's plans of relocating his people to Goguryeo soil, and because Emperor Taiwu's general Tuxi Bi was drunk, the Northern Wei forces could not give chase, and in anger, Emperor Taiwu imprisoned and then demoted both Tuxi and his deputy, the general E Qing (娥清) to being common soldiers, although he subsequently made them generals again. He then sent messengers to Goguryeo, demanding that Goguryeo turn Feng Hong over. Goguryeo's King Jangsu refused, albeit humbly requesting to serve Emperor Taiwu together with Feng Hong. Emperor Taiwu, at the suggestion of his brother Tuoba Pi (拓拔丕) the Prince of Leping, did not immediately carry out a campaign against Goguryeo. (By 438, however, Feng Hong and Goguryeo would have a fall out, and King Jangsu would have Feng Hong executed.)
