Symbiotic interaction could be achieved under certain circumstance, which is the inter - segregation of all cultures to some extent. This is ecological segregation on one side, and supernatural cycled segregation on the other. In Hulunbuir, supernatural cycle from forest hunters is achieved through ceremony made by urilen whereas even more worship to the eternal sky from steppe nomads is achieved through collective pro- gramming. In all cultures of Hulunbuir, differences are interactive and symbiotic due to different degree of the twp ways of cycle.
