Tung Chung, Hong Kong seeks helper who loves children

We are a Chinese family from mainland. Most of the time, there are the couple and two children. The son is 4 years old and the daughter is 2 years old. Maybe there will be a pet cat in the future. Every year, the grandparents may come to stay for a few months.
Our requirements: We hope you are cheerful, like children, and it would be better if you can cook some Chinese food and can Speak/listening a little Mandarin.
The daily tasks are simple. You need to pick up and drop off the children at the kindergarten, take care of them, cooking, and clean the room.
We can provide an independent bedroom with bunk bed, perhaps to live with the children for a period of time each year when grandparents are here.
Bouns will be provided based on your performance.
