Helian Bobo
In summer 428, Helian Ding sent an embassy to Northern Wei requesting peace. Instead, Northern Wei's Emperor Taiwu issued an edict ordering him to surrender, which he did not do. On a hunt at which he could see the old capital Tongwan from a distance, Helian Ding lamented that if Helian Bobo had made him crown prince, Tongwan would not have fallen. However, he himself did not dare to try to recapture Tongwan.
