The Confucian world is not coextensive with China and in some respects survives better outside it. Korea institutionalised Neo-Confucianism more thoroughly than China did during the Chosŏn dynasty, and the consequences persist: Seokjeon Daeje is performed at Sungkyunkwan and at 231 hyanggyo, the local Confucian schools; the accompanying Munmyo jeryeak preserves ritual music of Song and Tang derivation that no longer survives in China, and Korean specialists and Chinese scholars alike acknowledge this. Vietnam's Temple of Literature in Hanoi, founded in 1070, still holds eighty-two stone stelae mounted on tortoises recording the names of doctoral graduates from 1442 to 1779, inscribed on UNESCO's Memory of the World register. Japan absorbed the ethical and political vocabulary — Tokugawa Neo-Confucianism was the shogunate's official learning — while leaving funerals and the dead largely to Buddhism, so Japanese Confucianism has ethics and education without the ancestral ritual apparatus that defines it elsewhere.
