Chinese family looking for helper

My husband and I are looking for a domestic helper. We have a three years old son. The main duty will be preparing food, do houseworks and take care of our son when he comes home in the afternoon. Our apartment is near MTR Olympic station. You will have your own room. The room has window, closet and bed. Sunday or Saturday off is ok. We are looking for someone honest and reliable, with a loving heart for children.
