Chinese family looking for a domestic helper

Hi there, we are a family of 4: two adults and two children aging at 12 and 10 respectively. Grandparents live in China but visit us from time to time. Since two children are not small anymore, not much care needed. Main duties include cooking, house cleaning and marketing.We are an easy going and caring family, respect helper as long as she carries her duties well. Current helper worked with us for 12 years and she wants to retire and back to Philippines. Need a new helper who can work without too much supervision, has positive working attitude, willing to learn and listen.
