Western Wei
Eastern Wei's territorial size and military strength was far stronger than Western Wei's, and Gao made a number of attempts to try to end the division by conquering Western Wei, but the battles largely proved to be inconclusive, allowing Western Wei to stand. Periodically, Western Wei generals who had prior relationships with Gao would defect to Eastern Wei, and Gao at times carried out campaigns deep within Western Wei territory. However, Western Wei was able to portray Gao as a renegade general who expelled the emperor, and often during campaigns, local populace would assist Western Wei troops because they believed Western Wei's characterization. During this period, Gao also tried to foster harmony between the ethnic Xianbei and Chinese, persuading the Xianbei that they needed the Chinese to practice agriculture to be fed, and persuading the Chinese that they needed the Xianbei's military aptitude to protect them. He saw Emperor Xiaowu's flight as a blot on his personal history, so he treated Emperor Xiaojing with great formal respect, deferring to Emperor Xiaojing in all public occasions.
