They have kept searching and innovating to keep pace with the times and meet the needs of the readers. Following the writer's creative journey, the novels have proved not only the unity and inheritance but also their own unique features. That diversity is partly due to the fact that the writers have constantly searched for new ways of generalizing reality. Among them, the method of mythization has created a multi-faceted, multidimensional view of the world. So how does the method of mythization contribute to discovering the realistic essence of Vietnamese novels from 1986 to the present? That's the question this article addresses.","PeriodicalId":447825,"journal":{"name":"Vinh University Journal of Science","volume":"94 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115122296","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The reactionary forces are finding many ways to attack and distort the content of this theory. Prominently,they give other social theories to negate the revolutionary and scientific value of the theory of socio-economic models, distorting the interpretation of Marxism - Leninism on the historical - natural nature of the development of socio-economic models; reconsidering the issue of inevitability to pass through the social revolution to move forwards from capitalism to socialism; taking advantage of the dissolution of the Soviet Union and the socialist countries in Eastern Europe to deny the empirical value of the theory of socio-economic forms.

That will help students grasp the practical meaning of knowledge, and step by step understand how to apply it in practice and solve real-life problems.
