Primary school is a school where people receive formal education at the initial stage and is an important part of basic education. Generally, children aged 6- 12 are of primary school age, and the length of primary education at this stage is 6 years.

The word "primary school" did not specifically refer to schools at first. In the Western Han Dynasty, philology was called "primary school", and in the Tang and Song Dynasties, it was also called "primary school".

Reading must first be literate, master the form, sound and meaning of words and learn to use them. When children entered school in the Zhou Dynasty, they first learned harmony (referring to six groups of simple strokes from Jia). Six books refer to things, pictographs, sounds, meanings, annotations and debates, so "philology" used to be called "primary school", hence the name "primary school".
