Chinese family looking for helper

We are mainland Chinese family living in North point, Hong Kong Island. Our family is working mother+father+ 4.5 years old boy + grandma. Grandma is very healthy. She is here to help with the kid, no need to be taken care of.

Good English is a must, would be great if you can speak some Mandarin. Daily routine is mainly housekeeping + cooking + playing with the child. We hope you are honest, proactive, caring and quick learner. Drinking, smoking, loan borrowing is strictly prohibited in our house.

Reference letter or reference call with previous employer is a must.
