__Abstract:__

We investigate the subset of a discrete quantum group fixing a sequence of finite subsets,
and prove that it is a quantum subgroup.
Then with this concept we prove a mean ergodic theorem for discrete quantum groups.
This generalize the mean ergodic theorem for amenable discrete quantum groups.
