Qi Country's post-war rule over Xia Territory is actually relatively easy. All the difficult issues had already been cleared ahead of time during the war.
Cao Jie waged a complete annihilation war.
Emperor Qi ordered the extensive repair of Emperor Xia Xiang's mausoleum, personally wrote the sacrificial texts, and referred to him as the "Emperor of all ages." He granted the title of Marquis Anle, with hereditary succession to Si Cheng. He decreed the divine name "Lord Nanxiang" and honored him as the guardian deity of Xia Territory, granting incense offerings and encouraging the people of Xia Territory to worship.
He also pardoned all civil and military officials of the Xia side, declaring them "blameless for defending the territory."
Furthermore, Xia Territory was exempted from taxes for ten years to allow the land to rest and the people to recuperate.
