There were many reasons why Northern Qi destroyed Eastern Wei. First, Northern Qi's founder, Gao Huan, had used the chaos within Northern Wei to successfully seize most of Northern Wei's territory and population. Secondly, Gao Huan had cleverly used a counter-spy tactic, allowing Hou Mo and Chen Yue to assassinate Heba Yue, further solidifying Northern Qi's position. After that, Yuwen Tai, with the support of the Yuwen family, successfully destroyed Hou Mo and Chen Yue, avenged his boss, and occupied Guanlong Land. In the end, Northern Qi was established under Yuwen Tai's leadership. In short, Northern Qi's destruction of Eastern Wei was due to the resourcefulness and hard work of Gao Huan and Yuwen Tai, as well as the chaos within Northern Wei.
