What’s the most dangerous thing in this picture? Is it the young woman riding without a helmet (头盔)? No! She is riding her motorcycle on a wall. It’s called Tong Setan － “the wall of death” in Indonesian. This rider performed (表演) Tong Setan at a night carnival (狂欢节) in Bogor, Indonesia, on April 30. The wall is six meters high. People can watch riders from above. Tong Setan performers are big stars at traveling carnivals in Indonesia.    TEENS
