Why the two Han dynasties are the booming period of the development of traditional Chinese linguistics economy

The achievements of linguistics in the Han Dynasty marked the establishment of the ancient science of language in China. During the Han Dynasty, the country became more unified, and the unification and development of politics, economy and culture contributed to the unification of language. Literacy education was emphasized in the Han Dynasty, and the study of characters was developed. These linguists and linguistic works in the Han Dynasty were able to study the laws of Chinese language and characters from the actual situation of Chinese language and characters, therefore, it can be said that the achievements of linguistics in the Han Dynasty marked the establishment of the science of language in China in the ancient times. Ancient linguistics in China was also known as "elementary school", and the research content of elementary school had three main aspects: exegesis, philology, and phonetics. Elementary school research was mainly formed in the Han Dynasty, "Erya" is the beginning of exegesis, "Shuowen Jiezi" is the beginning of philology, "Shuo Ming" began to study the relationship between phonetics and semantics, and then, at the end of the Han Dynasty, the emergence of the study of anti-che, that is, the emergence of phonetics research.

The rise of character writing in the Han Dynasty was due to the transition from the Big Seal and the Small Seal to the official script, which required the study of Chinese characters; the emphasis on literacy education in the Han Dynasty as well as the disputes over the ancient and modern texts all contributed to the study of exegesis and philology. The study of language in the Han Dynasty marked the maturity of ancient Chinese linguistics, and laid down the path for the development of linguistic research in China, which had a great influence on later generations.
