The study of bet365 new user promo language and writing has a long historical tradition，Plays an important role in the construction and interpretation of bet365 new user promo civilization。Since the 20th century，With the introduction of Western theories and the large number of unearthed documents，The study of bet365 new user promo philology and ancient bet365 new user promo civilization faces unprecedented opportunities and challenges，At the same time, it also attracted a large number of scholars to pursue unremitting pursuit，Strive to explore the development rules of bet365 new user promo language and characters，Restore the original appearance and original meaning of ancient classics，Reconstructing the subject system of bet365 new user promo language and philology，Opened up many new research paradigms。Li Yunfu is one of the more representative ones。Over the years，He insists on tracing the origins，Seeking truth and seeking common ground，Striving diligently in the research of bet365 new user promo language and philology。

　Exposure to bet365 new user promo doors Gou Xuan Synopsis

Li Yunfu studied under the guidance of many experts in bet365 new user promo language and philology。After graduating from college，He went to Beijing Normal University for further studies，Learn grammar with Professor Zhang Zhiqiang，Learn "Ma Shi Wen Tong"，So most of his early papers were in the field of grammar。During graduate school, he studied exegesis with Professor Zhou Bingjun，Systematically study a large number of basic classics and ancient annotations，Built a solid foundation in ancient literature。His understanding of the "Biye" sentence in "The Analects" during this period、Explanation of Wang Niansun’s concept of “Lianyu”、The discussion on the exegetical issues of Yu Yue's "Mao Shi Ping Yi" shows his foundation in exegesis。At the same time，He studied rhetoric with Professor Li Weiqi，Co-authored the book "A Survey of bet365 new user promo Rhetoric in the Twentieth Century" with Lin Dingchuan。During PhD study，He studied philology with Professor Wang Ning，The doctoral thesis "Research on the Configuration System of Chu State's Bamboo and Silk Texts" conducted a pioneering study on the configuration system of national characters during the Warring States Period，At the same time, this case study also explores the theory of bet365 new user promo characters。

This kind of study experience of becoming a master in Yiduo has given Li Yunfu a relatively broad academic vision，It also laid the foundation for his research in many fields under bet365 new user promo linguistics。He often said: "Do learning，Theoretically, there must be subject boundaries，Many issues cannot be explained clearly without subject boundaries；But in practice, don’t be limited by ‘Xue Xue’，Interdisciplinary can broaden your horizons，Learn from each other。Systematic、Logic and questioning spirit are needed in all disciplines，With these scientific qualities, you can transfer to related disciplines。”His research involves bet365 new user promo character science、Exegesis、Lexical Semantics、Grammar、Rhetoric and other fields。For example, his "New Theory of bet365 new user promo Character Studies" conducted a new exploration and summary of the research theory of bet365 new user promo characters，In the field of lexical semantics，He has dozens of achievements including "A Brief Theory of Ancient bet365 new user promo Vocabulary" and "On the Analysis and Description of Lexicon Meaning System"。

In actual research，Li Yunfu not only pays attention to the description and verification of language and facts，And strive to improve Huawei theory on the basis of solid research on case studies，Use theory to organize materials，Use theory to explain phenomena，To achieve the effect of "Tongbo"。For example, "Several Issues You Should Pay Attention to in Classical bet365 new user promo Annotations in Middle School bet365 new user promo Textbooks" refines the principles and standards for judging the quality of classical bet365 new user promo annotations into whether they conform to the laws of language、Literary context、Logic、Objective reality, etc.；"On the Research and Expression of Word Relationships in Unearthed Texts" proposes the "Conformational System Research Method"，Based on the practice of textual research and interpretation, concepts such as “complete textual textual research”, “incomplete textual textual research” and “evidence chain” are summarized；"On the Analysis and Description of the bet365 new user promo Lexical and Semantic System" summarizes the method of analyzing related lexical items and describing the lexical meaning system as the "lexical item attribute analysis framework"。The above are the regular understandings summarized by Li Yunfu based on a large number of special case studies，It has great reference value for research in related fields。

In addition，Li Yunfu is based on his extensive involvement in the above research fields，There are also efforts to integrate these specific research areas，Migration to open up these disciplines，And try to summarize and explain it theoretically。For example, he presided over the major project of the National Social Science Fund "'Ancient and Modern Characters' Database Construction and Related Special Research"，Extensive collection of materials annotating "ancient and modern characters" from past dynasties，Comprehensive survey of the actual use of these "ancient and modern characters" in literature，Study the changes in the functions and relationships of bet365 new user promo characters from a diachronic perspective，Summary of the characteristics of word usage in different eras，Revealing the evolution of bet365 new user promo character usage，Analysis of the reasons for the evolution of bet365 new user promo characters’ functions，Comprehensive application of exegesis、philology、Vocabulary、Knowledge of philology，Summary of new vocational theory of bet365 new user promo characters。

Li Yunfu thinks，Is a theory good or not?，It mainly depends on whether its various concepts make sense，Various categories are not systematic，Can you describe and explain all the facts or most of the phenomena within the scope of this theory。Mastery of categories、A theory with strong explanatory power is a good and useful theory。The three-plane theory of bet365 new user promo characters proposed by him、bet365 new user promo Character Occupational Theory、Cross-cultural bet365 new user promo Character Research Theory、Term attribute analysis framework theory、Theory of meaning generation methods of compound words, etc.，It can not only effectively describe and explain various facts and phenomena of bet365 new user promo characters and bet365 new user promo language itself，And in the collection of ancient books related to this、Dictionary、bet365 new user promo character teaching and standards、The fields of compilation and research of ethnic minority writings also have certain application and reference value。Li Yunfu is not using Western theory to explain the phenomenon of bet365 new user promo language and writing，It is not to use the phenomena of bet365 new user promo language and writing to verify Western theories，Instead, we try to construct an actual theoretical system of language and writing that is consistent with bet365 new user promo characters。

　Good at questioning bet365 new user promo truth and bet365 new user promo truth

Another characteristic of Li Yunfu’s scholarship is that bet365 new user promo does not limit his opinions，Not afraid of authority，Don’t follow what others say，Good at asking questions，Always doubt where there is no doubt，Quickly discover the problems that Xi Yan does not notice，Even boldly questioning concepts and theories that have almost reached consensus in the academic community，Then put forward your own opinions。

Due to various reasons，There are some things that are inconsistent with the original intention of the ancients in the academic research on the history of bet365 new user promo language and philology。Li Yunfu opposes the arbitrary construction of academic history，In the article "Basic Principles of Research on bet365 new user promo Academic History", the experience of studying difficult issues in academic history is summarized as "seeking the truth、Seeking the truth、Seeking truthful comments”。He advocates that academic historical research should focus on the original meaning of the text、Starting from original examples and academic background，Sort out the ins and outs of related concepts and terms from the source、Evolution of origin，This has clarified many misunderstood theories and facts in academic history。For example, "gujinzi" was originally a traditional exegetical concept，Used to refer to different characters used to record the same term in different eras，Later, academic circles gradually had different understandings of this concept。Li Yunfu traces the history of research on the concept of "ancient and modern characters" in a series of articles，Clarified many misunderstandings，This leads to the repositioning of a series of related concepts。The "Compilation of "Ancient and Modern Characters" Character Groups Annotated in the Past Dynasties" and the "Academic History Series of "Ancient and Modern Characters"" edited by him are dedicated to restoring the history of "ancient and modern characters"。

In addition，Whether it is tracing back the origins of concepts such as "Lian Mian Zi", "Lian Yu", "Liu Shu", "Bian Wen", "Lian Lei De" and "Bi Yan"，Still questioning "the "regional characteristics" of Warring States writing", "the three elements of bet365 new user promo characters' form, sound and meaning" and "the unique style of writing"，Combined into a word" and other sayings，Or maybe a new interpretation of "phonetic and phonetic complement each other", "the foundation of character creation" and "shaped characters" and "from a certain character" in "Shuowen"，Li Yunfu always discovers problems from nearly conclusive propositions，Ask a question，After comprehensive review and combing of the original materials，peeling off the cocoon、Develop logical arguments one by one，Finally draw a new conclusion。

The reason why Li Yunfu was able to discover new problems，It is inseparable from his proficiency in basic classics related to bet365 new user promo language and philology。He emphasized reading common books in his studies，To dig deep into common materials that have not been noticed or misunderstood by previous people，Advocates interpreting new perspectives from familiar materials，When stating one’s own opinions, one is neither conservative nor seeking novelty，Thus, we can make an argument that is plain and fair but also contains new ideas。

　Keep the roots and innovate Seeking common ground and using bet365 new user promo

Li Yunfu attaches great importance to the research on the theory of bet365 new user promo language and philology。He advocates that academic research must be in line with the actual situation of bet365 new user promo language，The concept must be clear、Strict logic，You must also be able to describe phenomena effectively，Promote application。In the study of academic theory，He worked hard to achieve this。As in the field of philology，In the 1990s, he began to consciously change his mind from "body、structure、Analysis of various basic theoretical issues in bet365 new user promo character studies from a three-dimensional perspective，Propose "shape、structure、Occupation” are the three basic attributes of bet365 new user promo character ontology，Correspondingly, there are also three basic dimensions for studying bet365 new user promo characters，Focusing on these three dimensions to study bet365 new user promo characters respectively can form a bet365 new user promo character form system、bet365 new user promo character structure system and bet365 new user promo character occupation system，As three branches of disciplines, they together constitute a new research system of bet365 new user promo characters，This is the "Three Planes Theory of bet365 new user promo Characters"。In his "New Theory of bet365 new user promo Character Studies" published in 2012, he used the term "shape、structure、Analysis of the ontology of bet365 new user promo characters in the three planes of "occupation" as scripture，With "bet365 new user promo character attribute、Origin of bet365 new user promo characters、bet365 new user promo character relationship、bet365 new user promo character culture" is the latitude，Created a new framework of research ideas and knowledge system based on "three planes" to discuss issues from multiple perspectives。

He also paid special attention to the research on the "vocational" plane of bet365 new user promo characters，Committed to the research of "bet365 new user promo Character Vocational Studies"，The results of leading the research team members to explore the theory of bet365 new user promo character occupations and investigate the phenomenon of bet365 new user promo character occupations have been published in "Research on bet365 new user promo Character Occupation·Theory and Application" and "Research on bet365 new user promo Character Occupation·Use Phenomenon"，Thus promoting the development of bet365 new user promo character vocational studies。

In recent years，Li Yunfu actively advocates "cross-cultural bet365 new user promo character research"，He believes that this research has two meanings: the first is to use "cross-culture" as a research method and perspective，That is, studying bet365 new user promo characters in this culture in conjunction with external cultural factors；The second is to take "cross-cultural bet365 new user promo characters" as a research object，That is, studying bet365 new user promo characters in different cultural environments。Under his initiative and organization，The First International Seminar on Cross-Cultural bet365 new user promo Characters was held in Zhengzhou in 2018，More than 20 academic units at home and abroad have launched cooperative research on this。

In the field of lexical semantics，Li Yunfu also made outstanding theoretical contributions。For example, he combined conceptual field theory with semantic field theory，Combining sememe analysis and word attribute analysis，Combine the seme dichotomies with the seme polynomials，Combining synchronic description with diachronic comparison，Thus proposing new ideas for analyzing and describing the meaning system of bet365 new user promo words。This new framework for analyzing related terms and describing lexical meaning systems has great methodological significance for research in this field。He also noticed the fact of "different construction" in the development of bet365 new user promo vocabulary，Point out that the so-called "misunderstanding and misuse" of most compound words and idioms can be a reasonable explanation of "different construction"，This reveals an important way for bet365 new user promo compound words to generate new words and new meanings。For example, the original meaning of "wind comes from a hole" is that only when there is a hole can the wind come in，But you can use this word form to reanalyze new words with the same shape，Indicates that there is no hole but there is wind，Li Yunfu believes that this is a normal phenomenon of vocabulary development，Should not be regarded as misunderstanding or misuse。

The above theory proposed by Li Yunfu，Helps resolve various theoretical disputes，Can also explain various language and writing phenomena，It can also provide reference for solving practical problems in related fields。He can achieve the above results in academic research，Closely related to his respect for the actual situation of bet365 new user promo language and writing and his emphasis on logic。He emphasized that research should pay attention to distinguish similarities and differences，Rigorous inference，Follow the rules of logic。As he said: "Logic is an abstract form，Applicable to any science，When it injects certain content，It must be consistent with the actual content。So formal logic should require that each of its conclusions must be tested by practice，Only conclusions that have been tested in practice，Only can it be regarded as a correct and feasible conclusion。”
