How did the e culture become more unified during the Han Dynasty?

During the Han Dynasty, the e culture became more unified through the promotion of Confucianism as the state ideology, which emphasized social harmony, respect for authority, and filial piety. The establishment of a centralized bureaucracy facilitated the spread of standardized education and the civil service examination system, promoting shared values and knowledge across the empire.
