For a long time, the scholarly world of semasiology has mostly regarded the discipline as devoid of theory, but this is far from the truth. The speaker considers that this theory can be summarized by 'problem + explanatory proof + conclusion.' It is systematic, abstract, explanatory, testable, and hypothetical, and these are its five characteristics. According to this standard, the speaker introduces his viewpoints that there is a total of 76 traditional semasiological theories, whilst also confirming the name of each and outlining their content and value. Proposition of this theoretical system has taken inspiration from Wang Yinzhi's "tongshuo" (General explanation) included in his Jingyi shuwen (Narrating knowledge of meaning in canonical text), Duan Yucai's fan (all) in Shuowen jiezi zhu (Commentary to Discussing Language and Explaining Characters), and Wang Li's tonglun (General introduction) in Gudai Hanyu (Ancient Chinese). The speaker proposed that semasiological studies should conform to a four-part framework and considered that this new system for semasiological studies should comprise: 'Summary of theories of semasiological studies + semasiological studies of ancient texts + the semantics and lexicology of ancient Chinese + ancient Chinese phonology and semantics.' In this lecture, the speaker took the four-part framework as a premise and outlined the content and value of the 76 traditional theories of semasiological studies.
