Medical needs of the tenants: retired cadres, health professionals, your room has one or two of these two types of tenants to enable the medical facilities: the jungle doctor.
Pre-requisites for health care professionals, retired senior cadres, and housewives: 50% occupancy in paired apartments. Because each facility has a different full staff efficiency/usage efficiency, it's too much trouble to calculate exactly. If you are willing to calculate the staff efficiency/use efficiency you can also figure out the facility's limit number of receptions per hour. I've found that going by the limit number to set the number of tenants in an hour is more than enough, but tenants will complain that there are too many people in the facility, which is not conducive to 100% community satisfaction.
