But when we power off the node directly, the node status is " UNCLEAN (offline)" and the resource status is " Started(UNCLEAN) ".

You must have working stonith agent. Then when node unexpectedly goes
away other nodes will invoke stonith which confirms that UNCLEAN node
is down. After that pacemaker will change status to offline and will
proceed with restarting resources that were running on powered off
node.
