Chinese family looking for domestic helper

Hello, we are a Chinese family of 5 people, looking for a domestic helper who can work with us for long term. We have two children (4y and 8y), and normally 3 adults. My husband and I both go to work and usually either grandma or grandpa will be at home to assist you to look after children. Grandparents just live with us temporarily to offer help. They are very nice and easy to get along with. Your job will mainly be cleaning in the morning, and playing/looking after kids in the afternoon, and sometimes cooking lunch or dinner, washing dishes and doing laundry in the evening. Hope you are honest, responsible, work proactively and showing good working attitude, willing to play with children and know how to manage them. We would like to respect you and open to talk for any questions. If you perform good working quality, we are happy to provide more benefits, such as increased salary, bonus and flight tickets every year, presents, long service payment, etc.
