Chinese family looking for a helper

We are a Chinese family with two adults and three children. Our eldest child is 14 years old and is independent. The twins are 5 years old and attend full-day primary school. We are looking for a helper who is skilled in cooking or at least has an interest in it. We will provide incentive bonuses if you excel in this role. We already have one helper, but you won’t need to work with her. We will explain this in details during the interview. You will have your own room with a detached bathroom.
