Emperor Taiwu, however, ordered Feng Hong to also send his crown prince Feng Wangren (馮王仁) to Pingcheng to meet him, and Feng Hong refused, ending the brief peace, and by summer 434, Northern Wei resumed its periodic attacks on Northern Yan. Meanwhile, around this time, he also took the sister of Rouran Chilian Khan Yujiulü Wuti, Lu Zuo Zhaoyi, as an imperial consort and married his sister or cousin Princess Xihai to Yujiulü Wuti, to further cement the peaceful relations.
