Public security
Below the ministry level, there are public security bureaus for each province and directly administered city. These bureaus are headed by either a senior colonel or a lieutenant colonel of police, depending on the size of the population. Public security departments at each city or county and smaller substations through the country are staffed by about 100 personnel and are led by subaltern officers. They are organized roughly parallel to the ministry itself and have several divisions responsible for carrying out various functions.
