1, the system of protecting Fu was basically inherited by later generations, which provided the best education, so as to better fulfill the obligations of the emperor in the future, which was conducive to the stability and inheritance of the feudal dynasty.

Fu Bao system:

In ancient times, there were officials who specialized in counseling and teaching monarch and minister, namely teachers, Fu and Bao. As early as before the Western Zhou Dynasty, there were official positions such as surname, Taifu and Taibao, which were collectively referred to as "three fairs". Their deputies are Shao Shi, Shaofu and Shaobao, collectively known as the "Three Publics". Such officials are collectively referred to as masters, teachers' guarantors or guarantors.

Bao, responsible for the physical care of the prince; Fu, responsible for the moral cultivation of the prince; Division, responsible for the prince's knowledge education. These three aspects are fully responsible for the education and training of the prince, which shows that the court of the Western Zhou Dynasty has a plan for the education of the prince. Officials in Fu Bao are very cautious in selection and appointment, because he undertakes the heavy responsibility of educating and cultivating princes. Zhou Chengwang's "three fairs"-Tai Gong, Zhou Gong and Zhao Gong-are all famous ministers in history. Later generations also pay attention to the selection of Bao Fu officials who are "the best in the world, filial to their parents and knowledgeable". Fu Bao is credible, so he should take full responsibility for the prince's behavior.
