North Korea’s Choson Sinbo newspaper on Sunday released a new video through its YouTube channel showing its ceremony venerating Korea’s mythical founder Tangun on October 3.

The event, happening on the day both Koreas celebrate as National Foundation Day, took place in front of what the North claims is the tomb of Tangun in Pyongyang. North Korea started excavating the site in 1993, and its construction was completed in 1994.

The event started with meditation, and the traditional ceremony followed. Five participants in the first row bowed three times. This differs from South Korea, where one bows twice to their ancestors.
