"Gendarmerie of the Nether World" is one of the most common troupes in Taiwan. The number of trouper was ranging from 5 ~ 13, but mostly was nine. Because it was regarded as a religious troupe, thus they don't make any performance which has to do with entertainment. Their main duty is to escort palanquins in course of parade.
