Abstract

Background
The functions and characteristics of letters used for information exchange determine that they have occupied a place in the ancient academic history since their birth. As the academic summary period of the Qing Dynasty, the content of the letter turned to theory. Scholars exchange academic and textual research on classics and history through letters. And this research is helpful to analyze the regulation of information on modern people's emotional anxiety.

Research Objects and Methods
This paper mainly selects 6862 academic letters from the Qing Dynasty in the 18th century, of which 3060 involve textual research. According to the specific vocabulary categories and materials involved, it is divided into 8 sub categories for quantitative and qualitative analysis. The results show that through examples, lists and textual research, the main materials of academic letters in the Qianjia period highlight the academic value of analyzing letters in the Qing Dynasty from the aspects of corpus, philology, linguistics and history. The data of this paper mainly comes from the letters from 1700 to 1800 in the collection of poetry and prose of the Qing Dynasty. The standard of material selection is whether literature, language and textual research are involved. At the same time, the communication anxiety scale is also used. The Interaction Anxiety Scale (IAS) [17] compiled by Leary is used. There are 15 questions, a single dimension, and a 5-level score. From 1 to 5, it means “very inconsistent” to “very consistent”. The higher the score, the greater the degree of social anxiety.

Results
The Qing Dynasty Correspondence corpus has objectivity, authenticity, richness and particularity; It embodies the value of text collation in philology; In linguistics, it embodies the value of the combination of theory and textual research practice, and the combination of point and aspect; In history, it embodies the value of mutual proof of historical facts. The practice of letter vocabulary textual research can be combined with the achievements of modern language research to provide information supplement for language research. The exegetical achievements of academic letters in the Qing Dynasty are an important part of the achievements of traditional linguistics. Among them, the most discussive and characteristic is the textual research on Jingchu vocabulary and its related problems. Collating and studying the contents of lexical textual research involved in Qianjia academic letters can not only provide theories and methods for the comprehensive study of lexicology, but also provide reference for the textual research of letters in the Qing Dynasty and other periods. At the same time, the social anxiety of letters was the independent variable, and aggression and depression were the dependent variables. When the self-efficacy of managing depression / pain was the mediating variable, the total effects of mediating effect were 40.61% and 34.06% respectively; When the self-efficacy of managing anger / anger was the mediating variable, the total mediating effect was 55.77% and 31.81% respectively.

Conclusion
the letters of the Qing Dynasty in the 18th century can make up for the lack of monographs and historical materials and return the literature to its original truth; It helps to outline the trend of Confucianism in the Qing Dynasty, improve the academic pedigree of people in the Qing Dynasty, provide necessary language support for the research of academic history, cultural history and other disciplines, and promote the in-depth development of literature collation and collation. To sum up, the emotional regulation of ancient people through ancient letters is also conducive to the mental health of contemporary people.
