Discussing the influence of parents' individual characteristics on parents' education in public libraries is helpful for public libraries to carry out targeted parents' education. Through the questionnaire survey, this paper finds that the gender, age, educational background of parents and the age of children have a significant impact on the development of parent education in public libraries. Women, parents with high educational background and parents of children aged 0-12 have a higher degree of intimacy with their children, which is the best target group for parents' education in libraries; men, parents of 46-60 years old, parents with low educational background and parents with children aged 13-18 years old need to improve their awareness of parents' education; parents of 46-60 years old and low educational background need to improve their own educational theory.
