Yulin, Shaanxi
In 427, after fighting dangerously but with Cui at his side, Emperor Taiwu captured the Xia capital Tongwan (in modern Yulin, Shaanxi), forcing the Xia emperor Helian Chang to flee to Shanggui (上邽, in modern Tianshui, Gansu) and allowing Northern Wei to take more than half of Xia territory.
