China's research on Chinese characters has a long history, but this science was not called philology at first, let alone Chinese characters, but called.

It should be called elementary school.

The following is an introduction to primary schools:

Primary school, also known as Sinology in China, includes philology of analyzing glyphs, phonology of characters, exegetics of explaining the meaning of words, and research on the interpretation and interpretation of pre-Qin classics, so it is also called a vassal of Confucian Classics.

In ancient times, those who studied textual criticism and phonology were called primary schools. Each character has three parts: 1. Glyph; 2. Meaning; 3. Pronunciation. In the Han dynasty, this difference was not significant. At the end of Song Dynasty, Wang Yinglin's Jade Sea has been divided into three types: systematic, exegetical and phonological. "Sikuquanshu" in Qing Dynasty divided primary school books into three categories: exegesis, word books and rhyme books.

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 six books (Liu Jia refers to six groups of branches with simple strokes for children to practice Chinese characters. Six books refer to things, pictographs, sounds, meanings, notes and arguments. It was called "primary school" in the Western Han Dynasty and "primary school" in the Tang and Song Dynasties, hence the name "primary school".
