Burning Man is an anti-tradition carnival initiated by an organization called "Black Rock City, LLC", lasting for eight days. It has been held yearly since it was开创ed in 1986. The venue is selected at the Black Rock Desert, Nevada, USA (located 150 kilometers northeast of Reno City). Participants from different places have different goals. They describe Burning Man as a large experiment of radical self-expression. The time is generally from the end of August to the beginning of September, on the American Labor Day. The number of participants keeps increasing year by year.
