The results show that the venue and time of the event were not fixed; competition items increase year by year; performance items increase the mostly; the number of gold medals won by men was positively correlated with the number of gold medals won by women; the overall scale of the games is on the rise; and the competitive strength of the national games is not consistent with the level of social and economic development. Therefore, the games of ethnic groups in Yunnan can be innovated by setting the holding time in combination with national festivals, highlighting featured projects and diverting competition venues, and tracing the origin of ethnic origin to stimulate the development of tourism push the games to national movement.
