Confucianism
Only 0.2% of contemporary South Koreans give "Confucianism" as their religion. However, the influence of Confucian ethical thought on other religious practices, and on Korean culture in general, remains ubiquitous and pervasive.
Confucian rituals are still practiced at various times of the year. The most prominent of these are the annual rites held at the Shrine of Confucius in Seoul. Other rites, for instance those in honor of clan founders, are held at the numerous shrines found throughout the country.
