Foster care refers to the way that children under the care of the civil affairs department are entrusted to eligible families for raising after the prescribed procedures. There are three explanations for foster care. First of all, it is not raised at home. Second, it refers to entrusting children to others for raising; Third, temporary resettlement to a certain place for support; Fourth, it refers to the allocation or entrustment of livestock and poultry to others for adoption. According to the relevant laws and regulations, an important difference between "foster care" and "adoption" is that foster care is carried out on the basis of not changing guardianship. Foster children enter the family foster care, and the foster family is responsible for raising them. Foster children enjoy the living, medical and educational expenses given by the government.

General family foster care is a long-term behavior, basically taking "year" as the unit. However, if the biological parents or family adoption file a claim and the foster family is found to have done harm to the foster children, the welfare home has the right to terminate the agreement at any time.
