Why would Chinese rulers have preferred that their people practice Confucianism over Buddhism?

Chinese rulers preferred Confucianism over Buddhism because Confucianism emphasized social harmony, hierarchical relationships, and loyalty to the state, aligning closely with the governance needs of a centralized bureaucracy. It promoted moral education and civic responsibility, fostering a sense of duty among citizens. In contrast, Buddhism, with its focus on personal enlightenment and detachment from worldly affairs, could potentially undermine the authority of the state and social order. Thus, Confucianism was seen as a more stabilizing influence for maintaining political control and societal cohesion.
