Is Shenzhen Nanshan No.2 Primary School a closed school?

Shenzhen Nanshan District No.2 Primary School is a semi-closed school. The school gate will be closed during school hours, and only parents and staff can enter the school. But during non-school hours, the door will be open and outsiders can enter the campus. Therefore, although Nanshan No.2 Primary School is not a completely closed school, certain safety measures have been taken to ensure the safety of students and the quality of education.
