Nima-odsor was a member of the Central Committee of the Kuomintang and of the Mongol Local Autonomy Political Affairs Committee. He was a close associate of Ünenbayan and Jodbajab. In January 1936, Nima-odsor, Ünenbayan, Serengdongrub, and Demchugdongrub went to Zhangbei for a meeting with Jodbajab. In that meeting, they discussed Jodbajab's deployment of cavalry police in six counties in northern Chahar Province (demilitarised by the Chin–Doihara Agreement in the wake of the North Chahar Incident) in response to Manchukuo troops' occupation of the area under Li Shouxin the previous month.
