The term au pair is French and means "by mutual agreement".
An au pair is a young person aged 18 to 28, unmarried with no children, going abroad for a temporary period of time and living with a host family.
Whilst living abroad, the new temporary family member assists his or her host family with childcare and light housework.
The au pair in a Chinese family is as a foreign sister/brother to take care of children and help them to improve English or other languages.
Therefore, au pairs receive monthly allowance, live free of charge with their host families, just as regular family members, and share meals with the families.The monthly allowance and amount of duty hours are defined by the regulations of the respective host.
