This video focuses on the Bag Jun Sum’s annual Oboo (stone cairn) ritual in Hobgosair. Among Torghuts, a Sum is the smallest administrative unit since the Qing era. Each Sum comprises four Tens, with a Ten being a family lineage. Therefore, in most cases, a Sum consists of four Tens. There are fourteen Sums in Hobogsair, each with its own Oboo for worship and annual rituals, in addition to the large Oboo that brings together all fourteen Sums. During the ritual, Soka, one of the local esteemed elders imparted his knowledge of the Oboo ritual. He said: “We are all descendants of one father.” Reflecting on his forty years of attendance at the Oboo ritual, he also remarked, “My seat has shifted from a lower position to this, where I suddenly find myself on one of the highest seats this year.” Despite the challenges posed by Covid-19 and recent political tensions, he emphasised the importance of preserving this cultural tradition in changing times.

Soka also mentioned that every new household of the Sum is expected to attend the Oboo with one whole sheep and register their new family within the Sum.
