Emperor Wen of Sui is recorded as having withdrawn his favour from the Confucians, giving it to "the group advocating Xing-Ming and authoritarian government". But Wen might be said to have already been steeped in a Legalist tradition followed by the aristocratic institutions of the northern dynasties, who concerned themselves with functional organization and social hierarchy. The Sui dynasty and Tang dynasty were largely based upon the Western Wei and Northern Zhou, refining pre-existing institutions and taking measures against the aristocracy.
