Ethnology, Ecology, Special History, Microbiology: In the first half of this year, the Ministry of Education launched a new round of national key disciplines evaluation and supplementary work. Ethnology and ecology, the original two national key disciplines in our school, participated in the evaluation, and related disciplines participated in the new round of supplementary declaration. Recently, following the announcement of the list of national key disciplines by the Ministry of Education, the original two national key disciplines, ethnology and ecology, passed the assessment with excellent results and retained the qualifications of national key disciplines. In the new round of supplementary work, the special history and microbiology of our school have been added as national key disciplines through peer expert review. As a result, the number of national key disciplines in our school has increased from 2 to 4. Discipline construction is the leading and core of all work in colleges and universities. Since the Ninth Five-Year Plan, our school has attached great importance to discipline construction. In accordance with the school-running idea of "based on the frontier, serving Yunnan, improving the level and running a characteristic", and closely combining with the needs of economic and social development, the discipline construction has made great progress by further gathering discipline teams, optimizing the discipline structure and streamlining the discipline direction. We have made good achievements in the evaluation and supplement of national key disciplines, which is the result of our long-term attention to discipline construction, marking the new development stage of discipline construction in our school. During the Eleventh Five-Year Plan period, the school formulated the Implementation Plan for Discipline Construction of Yunnan University. In accordance with the principle of classified guidance and hierarchical construction, we carefully analyzed the location and resource advantages of Yunnan Province and Yunnan University, further intensified the transformation from location and resource advantages to subject advantages, made great efforts to build a discipline with distinctive advantages and a more dynamic and competitive discipline system, and embarked on a road of discipline development with more distinctive characteristics. Strive to make some advantageous and characteristic disciplines reach or approach the international first-class level, and provide strong discipline support for realizing the transformation of Yunnan University from a teaching and research university to a research and teaching university, and building Yunnan University into a high-level university that is "first-class in the west, advanced in China and internationally renowned".
