In the depths of the vast Horqin grassland, there is an ordinary peasant couple. The husband has only a fifth-grade education, the wife has only a second-grade education, and there are three men, three women and six children. Three daughters graduated from universities one after another, while three sons all completed their doctorates and became experts in their respective fields. This is the legendary story of "Three Doctors of the Peasant Family" circulating on the grassland in Inner Mongolia.

Dr Dong Jinyu is the eldest of six children on this farm. Based on his own growing experience, he summed up the experience of parents in educating their children, and combined with his 25 years of research experience in pedagogy, psychology, sociology, brain science and neurolinguistics, he founded a revolutionary family education theory. Since the establishment of the parent-child relationship model, Dr. Dong Jinyu has successively established teacher education model, one teaching children to learn model, two teaching children to learn model, 0-3 years old children education model, 3-6 years old children education model and gender relationship model. These models clearly and accurately reveal the basic laws of education.
