The recruitment clause is that it is a married woman. Regardless of age, all married women come to interview for this dubious job, saying that special qualifications are unnecessary. The job content is to be dispatched to a requested house and do housework, cooking, etc. as a housewife for a day. If you look only at this, it's just a housekeeper business. However, the reason for specifying a married woman in the recruitment requirements was hidden.
