Healthy active grandma looking for helper

I am a healthy and active grandma looking for a helper to help me with my housework. My children are grown up and in Hong Kong having started their own families and I happily host them every Sunday evening for family dinner (hence requesting a helper who can accept Saturdays off instead of Sundays), but otherwise I mostly just need help with the housework, cooking and marketing. I would ideally like someone who is warm, friendly and organised with experience cooking Chinese food, though I am happy to teach and train the right candidate. I am over 70yo, but am very healthy and active (I gym and swim everyday!) so this is not an elderly care role. But living by myself, I would like to have some help around the apartment. I would like someone to start in mid/end December if possible, but can be flexible for the right candidate. Salary negotiable depending on experience. PS. My son is helping me with this search in case you are wondering why a man is the one getting in touch first.
