Abstract:2022 and 2023 mark the 70th anniversary of the Chinese Society of Microbiology and Acta Microbiaogica Sinica, respectively. China's prokaryotic microbial taxonomy research has gone through 70 years from starting from scratch, tracking and imitating to gradually entering the international stage, from following and running to being in the international advanced ranks as a whole, leading international counterparts in some fields, and providing microbial data services for international counterparts. These achievements are the result of the efforts of generations of scholars in the field of prokaryotic microbial taxonomy in China, and the result of the resonance of the same frequency with national development and national rejuvenation. Especially in the past 30 years, China's prokaryotic microbial taxonomy has made remarkable achievements in terms of theory, method innovation and novel species discovery, and its status and influence in the international community have been increasing, and it has gradually become the leading force in the field of international prokaryotic systematic taxonomy. Based on respecting history and being objective and realistic, this review sorts out the development context and achievements of bacteria and archaea taxonomy and related fields in China in the past 70 years, and looks forward to the latest development direction in this field.<
