“网格” means grid, and “员” is a person. Together the term means the person who manages the grid. The term is related to China’s administrative management system. Under the system, the district government divides its jurisdiction into three levels of grids. Traditional neighborhoods were considered large grids; smaller communities within each neighborhood were designated as medium grids; residential areas in each community were further divided into small or basic grids. The people who manage the small or basic grids are called grid attendants.
During the COVID 19 pandemic, a grid attendant, either full-time or part-time, would perform health checks, acquire information about the movement of local residents, conduct contact tracing, and implement preventive measures.

Better consult your community grid attendant for that. They are the most reliable source and you can trust their information.
