Zhu Xi_

Zhu Xi, formerly romanized Chu Hsi, was a Chinese philosopher, historian, politician, poet, and calligrapher of the Southern Song dynasty. As a leading figure in the development of Neo-Confucianism, Zhu Xi played a pivotal role in shaping the intellectual foundations of later imperial China. He placed great emphasis on rationality, opposed mysticism and religious experience, and constructed a huge philosophical system. His extensive commentaries and editorial work on the Four Books became the core texts of the imperial civil service examinations from 1313 until their abolition in 1905. He advanced a rigorous philosophical methodology known as the "investigation of things" (格物) and emphasized meditation as an essential practice for moral and intellectual self-cultivation. Zhu Xi's thought exerted profound influence, becoming the official state ideology of China from the Yuan dynasty onward, and was later adopted in other East Asian countries such as Japan, Korea, and Vietnam. In these regions, his Neo-Confucian doctrines were institutionalized through educational systems and civil service examinations, shaping political ideologies, social hierarchies, and cultural values for centuries.
