array of Han Chinese practices and institutions, such as holding of sacrificial ceremonies in the northern and southern suburbs of his capital in 1149 (cf. ceremonies conducted at the Temple of Earth and Temple of Heaven in Beijing during the Ming and Qing dynasties), the use of the imperial carriage in 1151, a system of feudal rights in 1156, and the Song dynasty's shan-hu (山呼) style of court ceremonies in 1157. Digunai also introduced the imperial examination system in 1150 and set up the Imperial Academy in the following year. In his pursuit for greater sinicisation and the desire to acquire the Mandate of Heaven, Digunai moved his imperial court from Shangjing (present-day Acheng District, Harbin, Heilongjiang Province to Yanjing (present-day Beijing) in 1153. In 1157, he ordered the destruction of the imperial palaces in Shangjing. In contrast to the traditions of the Tang and Song dynasties, which rarely imposed corporal punishment on the members of the society's educated elites, Digunai continued the Khitan and Jurchen tradition of floggings with gusto, sometimes enjoying personally watching his subjects – including chancellors, censors, and a princess – beaten with poles or whips. Assassination Digunai's attempts to conquer the Southern Song dynasty and unify China under the Jin dynasty's rule ended in failure when his fleet was defeated by Song forces at the battles of Tangdao and Caishi in 1161. Many of his officers defected and in some places the people rebelled against him. His subordinates conspired against him and assassinated him on 15 December 1161 in a military camp near the Yangtze River. Digunai's cousin, Wulu, who had led a rebellion against Digunai's rule, was proclaimed the new emperor.
