Caregiver for Senior Wanted

My father has dementia. My mother is needing help to take care of my father because it’s difficult to do it alone. Here are some of the care needs: helping him floss and brush teeth, taking him for small walks, do some exercises or games with him. She’s hoping a few hours a few days a week. Something like 3 times a week for 2-3 hrs. Mandarin speaking is required.
