2 Adults 2 children Chinese family looking for help

We are a busy family with both husband and wife working on weekdays. We have two lovely daughters, aged 4 and 2. One grandparent stays with us to help look after the children. We need help with daily household chores, such as cleaning, shopping, cooking, and taking our elder daughter to and from kindergarten. Occasionally, you might also need to assist the grandparent in looking after the children. We are looking for someone who is diligent, responsible, and easy to communicate with. The ability to speak English is required, and it would be ideal if you can also speak some basic Mandarin.
