Wuqimai was the fourth son of Helibo and his primary consort, Lady Nalan (拏懒氏).

In October 1125, Emperor Taizong waged war against the Han Chinese-led Song dynasty and ordered his fifth brother, Wanyan Gao (完顏杲), to lead the Jin armies to attack Bianjing (present-day Kaifeng, Henan Province), the Song capital, from two different directions.

The Song general Li Gang (李綱) led fierce resistance against the Jin invaders.

During his reign, Emperor Taizong laid and strengthened the Jin dynasty's political system and institutions.

His descendants were massacred by Digunai (Prince of Hailing), the fourth ruler of the Jin dynasty, as a political move to eliminate possible contenders to the throne.
