Toot, toot! The world religions train continues down the track! This is a flag for Cheondoism, a native Korean religion (in north and south, stronger in the North according to Wikipedia) that is based heavily on Confucius thought apparently. It interestingly rejects the idea of an afterlife. This flag was a 100% not made by me, it was made by user Aethelwolf Emsworth (on Wikimedia) and released into the Public Domain.
