Helian Chang
In spring 428, with Daxi's subordinate Yuchi Juan (尉遲眷) sieging Shanggui, Helian Chang withdrew to Pingliang. Meanwhile, Daxi's forces arrived, but were being afflicted with diseases. Helian Chang took the opportunity to counterattack, forcing Northern Wei forces to take refuge in Anding. Helian Chang attacked on a daily basis, and it appeared that Anding would fall to him. However, Daxi's subordinate Anchi Jia (安遲頡) and Yuchi then, without Daxi's approval, undertook a daring plan—as Northern Wei soldiers were by now familiar with Helian Chang's appearance, one day, when Helian Chang was again attacking Anding, Anchi and Yuchi led soldiers to make a strike intending to capture him. Helian Chang fell off his horse, and Anchi took him captive. Helian Ding withdrew to Pingliang and took the throne himself.
