How to find someone without monitoring in the old community

If you want to find someone in the community quickly, then the first way is to find the property directly, because the property must be very familiar with all the residents in the community, and we can find the person we are looking for quickly through the property. Another way is that we can ask the security guard at the door for help, because the users of this community have to go from Dalian every day, so these security guards are familiar with the residents in the community, and they can be found quickly through these security guards.
