赫連昌
By this time, though, the Northern Wei emperor had arrived at Pingliang, and, with Helian Chang (whom he had created Prince of Qin) with him, he had Helian Chang to try to persuade the defender of Pingliang, Helian Ding's younger brother Helian Shegan (赫連社干) the Duke of Shanggu to surrender. Helian Shegan initially refused. Helian Ding, hearing that Pingliang was under attack, tried to return to Pingliang to relieve it, but on the way he encountered the Northern Wei general Tuxi Bi (吐奚弼), who tricked him by pretending to be a weak force, drawing an attack from him. Tuxi then defeated Helian Ding, who was then forced to withdraw to Chungu Plains (鶉觚原, in modern Pingliang). Northern Wei forces surrounded him, and his army became hungry and thirsty. After several days, he forcibly fought his way out of the siege, but his forces mostly collapsed, and he himself was badly injured. He gathered the remaining forces and fled to Shanggui.
