 Having usurped the throne, Wanyan Liang embarked on the program of legitimising his rule as an emperor of China.In 1153, he moved the empire's main capital from Huining Prefecture (south of present-day Harbin) to the former Liao capital, Yanjing (present-day Beijing).Four years later, in 1157, to emphasise the permanence of the move, he razed the nobles' residences in Huining Prefecture.
