This ritual is held annually to renew a wobo (sacred mountain-top cairn). The wobo is referred to as Shuguo Wobo 'Big Wobo', and the deity thought to inhabit the cairn is called Wobo Laoye 'Wobo Grandfather'. Wobo Laoye is considered the protector deity for the entire Sanchuan Mangghuer region. Participants in the ritual come from Wangjia, Yangjia, and Qijia, three large Mangghuer villages.
