Confucianism.

Explanation:

An important concept that became a crucial part of Chinese culture was Confucianism. Confucianism emerged in the "Age of Warring States" (500-221 BCE), and was considered to be the official ideology of the Chinese state after its reunification by the Han Dynasty in around 200 BCE. The "Confucian answer" to China's problems was based on the power of moral behavior.

Confucianism was based heavily on filial relationships, Chinese tradition, and Chinese academia. Confucianism's impact on Chinese culture grew so large that it actually became synonymous with the culture, and was a central element of China's bureaucracy.
