Is Huilong New Town a closed community? How safe is it?

Hello, Huilong New Town was built in 2002 and is in a semi-closed state. The residential area is a new century property, one of the best in the surrounding area. You can enter the community during the day, but there is an aunt on duty in the building. Most of them are strangers in Shanghai who can't get in without saying hello. Community security guards patrol 24 hours a day.
