Primarily for cooking, housekeeping, and baby care

I live at GRAND MAYFAIR, 29 Kam Ho Road, Yuen Long, New Territories Hong Kong, I have a separate workers' flat with a bathroom and shower. Currently, in my family, there are two elderly people (in good health and fully capable of daily self-care), one adult, and three children (one 17-year-old, one 9-year-old, and a 5-month-old baby) in the household. I need to hire a domestic helper, primarily for cooking, housekeeping, and baby care.
