Hot springs are one kind of extreme environment. A major feature of hot spring organisms is that they have a strong regional distribution. Tengchong is a volcanic and geothermal area, which is rare in mainland China. This filed trip was arranged in the Rehai of Tengchong. Through this filed trip, the students combine the theoretical knowledge that they have learned in the classroom with the extreme environment, deepen their understanding of professional knowledge, have a systematic understanding of extreme environmental life, and learn to collect hot spring water samples and sediment samples, determination of the physical and chemical parameters, isolation and identification of spring microorganism. Systematically studying on the separation and culture of hot spring microbial resources. Exploring the potential of microbial resources in hot springs to contribute to the research in the field of extreme microbiology.
