Through the ages，The skills of many traditional industries are mostly passed down by word of mouth。Because these skills are related to the livelihood interests of generations，People have even established an unwritten rule of "passing on the male rather than the female"，And most of them are passed down in argot and jargon。Like Cantonese Opera、The argot lingo of many traditional opera and folk art groups such as Kun Opera and cross talk，And the argot lingo of Jilin’s ginseng harvesting industry，The argot jargon of Hubei bricklayers，Zhejiang Longquan、The "Gushan dialect" popular among the "Gumins" in Qingyuan and other places，The argot jargon of Fujian Yongan tofu industry，The argot jargon of Shanxi’s hairdressing industry，The argot lingo of shadow puppet artists in Laoting, Hebei Province，The secret “tin language” of Jinhua tinsmith’s tin-making formula that is still used today，The argot lingo of Wu Qiao’s acrobatic performers，Even the argot jargon of the antiques and antiques industry in various places today，It can be described as colorful，Each has its own merits。Argot jargon is an important tool and basic information carrier for the inheritance of skills and even stunts in these industries。For example，The prosperity of Cuju in Song Dynasty，There is still a collection of "Cuju Pu·Yuanshe Jinyu" that compiles more than 130 argots and lingo of the Cuju industry at that time。To contemporary times，Although these Cuju argots of the Song Dynasty are no longer popular among football players and fans，But it has become an important "language fossil"，bet365 champions league is strong evidence that China is the birthplace of world football。

In view of the confusing and inelegant terms of address in bet365 champions league lingo and jargon，It needs to be freed from social prejudices and misunderstandings，Restore its original character as a rare folk language and rare cultural heritage。Mr. Qu Yanbin passed systematic research，It is recommended to use "Jinyu" as an elegant name for "argot jargon"，In order to benefit the discovery of this language and cultural heritage、Protect and even scientifically develop and utilize。

Relative to regional dialect，Folk secret language is a social variation of language。A language code used as a subcultural group，Folk secret language reflects non-mainstream cultural phenomena，Closely related to specific folklore phenomena，It is an important and interesting branch field worthy of discussion，can be used as a special window to observe multi-level social history and culture。Ministry of Education、The research report "Folk lingo in social life" of the second part of the "Report on the Situation of bet365 champions league Language Life (2009)" issued by the State Language Commission shows，In real social life，Argot jargon remains active in the languages ​​of many social groups，Cannot be ignored。

As the latest achievement in the field of folk linguistics，Research on the National Publishing Fund project "An Interpretation of bet365 champions league Hidden Languages ​​in Past Dynasties" published by the Research Press in September 2020 (edited by Qu Yanbin，1.65 million words) just came out，Is listed in the fifth issue of "China Publishing Group's Good Books List" in 2020，Immediately entered the new book list recommended by the "Chang'an Street Reading Club" Issue 20200908。This work has received such attention，There are at least three reasons。

First，This book is the latest in the academic history of this field after the "National Dictionary of Cutouts from All walks of life", "The Dictionary of bet365 champions league Argot Jargon", "The Big Dictionary of bet365 champions league Secret Languages", etc.，The first specialized dictionary and document collection compiled in the form of mutual interpretation of relevant and rare documents that exist today，Is the cornerstone for this discipline to move towards a new milestone。This book selects about thirty types of bet365 champions league lingo and jargon from the known literature of more than one hundred types of bet365 champions league lingo from past dynasties，more than 20,000 entries，Gather relevant content of the selected documents after each entry，Divided collection and mutual interpretation，Easy to use。

Second，The lingo material of many industries compiled in this book，It is a "language fossil" in the deep structure of society，Can be used to explore the cultural secrets of the lower class in ancient and modern times，Restore many on-site situations of social life and historical memories，So scholars can use this to explore the folk language landscape in the microscopic scene of social and cultural history。In this sense，The rare value of the texts selected for this book is particularly obvious。The author mentioned，A "Newly Engraved Essentials of Jianghu" published in the late Qing Dynasty，Because there are very few in existence，Even the cyanotypes from decades ago，Already listed in special collections in some famous libraries。As a rare film in bet365 champions league history、A work that can be called a classic of bet365 champions league lingo and jargon，His fate remains the same，Those transcripts of some internal lingo transmissions in the industry that were gradually discovered by later generations，The situation is even more worrying: due to ignorance、Misreading and other reasons，These precious materials are gradually disappearing。Ignore this kind of "language fossil" that reflects the deep structure of history and culture，Analysis、Understanding the trajectory of social and cultural history in the past, there will be a lack of strong evidence，I have to say it is a pity。

　Third，This book is academic in nature、Informational、Informative and instrumental functions，Rich content、Informative，It is to read relevant historical documents and popular literary and artistic works since the Song, Yuan, Ming and Qing Dynasties、An important reference book for interpreting related words，Has high academic value and practicality。As the author said in the postscript at the back of the book，This book has the function of a "general and specialized reference book"，is a special collection of literature materials for reference in academic research on bet365 champions league lingo and jargon，A compilation of relatively obscure academic literature on topics for academic research reference，A preliminary centralized sorting and preservation of relevant historical documents"，The most detailed so far、A comprehensive corpus of bet365 champions league lingo and jargon，It is a most unique and profound social memory archive。This book can also be used for linguistics、Folklore、Literature and Art、Sociology、Cultural Studies、Analysis of doubts and doubts related to issues in history, public security, justice and other related fields，Provide important references。
