Why is Ningbo Yunting Apartment blockhoused?

Sorry, I don’t know the specific reason why Ningbo Yunting Apartment is a blockhouse. However, I can provide some possible reasons:

1. Rat problem: Due to poor hygiene in the apartment corridors, rats move frequently. In order to prevent rats from entering the room, turrets may be used to prevent rats from entering the room. Prevent mice from entering.

2. Safety issues: In order to ensure the safety of residents in the building, turrets may be used to enhance the safety of the building.

The above reasons are only possible speculations, and the specific reasons may require further investigation and understanding. It is recommended that you seek more accurate information from relevant institutions or professionals.
