What's the name of the place where Rong County specially keeps files? Is this the personnel safety bureau?

No, not the same place. The full name of the Labor and Social Security Bureau is the comprehensive service hall of labor and social security. Generally referred to as the labor insurance bureau. District personnel is the district personnel human resources bureau or the district personnel human resources market. It's not the same place, but it usually doesn't get too far. It's all on the road where the district government is located.
