Caring for 91 year old elderly lady

Hi I need a helper who can care of my 91 year old mother but must be able to speak some Cantonese. Helping her to get up, she can walk and she’s pretty independent but her mobility is deteriorating fast and she’s losing muscle strength. You will need to assist her to the shower, toilet and help her up and down the stairs or as she lives in a modern village house. Her daughter and son in law will provide her meals but you just need to do some cooking and maintain the house in reasonable condition. Some basic Cantonese is good as she doesn’t speak English.
