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. This video shows: the valleys and mountains surrounding Shuguo Wobo; the arrival of villagers at the cairn; villagers making offerings of incense, paper, oil lamps, branches, wool, replica wooden weapons, and prayer flags; villagers singing the Tibetan Buddhist mantra of Avalokitishvara, Om mani padme hum; and the arrival of local Tibetan Buddhist monks. 每年都举行这个仪式更新沃博（神圣的山顶上的石冢）。 把沃博称为殊果沃博 “大沃博”，并且认为神，沃博老爷居住在石冢。沃博老爷被认作是土族三川地区的守护神。参与这个仪式的来自于三大土族村的王家和杨家、祈家等。这个影片展示了殊果沃博周围的山沟和山、村民们到达了石冢、 村民们由香和纸、油灯、树枝、羊毛、木制武器，以及经幡供奉。村民们唱藏传佛教中观音菩萨的咒语（唵嘛呢叭咪吽），还有本地藏族佛教的僧侣。
