Under the guidance of the tour guide, the students visited the Zhijindong Cave Museum for study and to watch 4D films, allowing them to see and experience the rich and colorful, magical and magnificent nature with their own eyes and in person. The students who participated in the event said, "Today's World Earth Day activity has led us to explore the mysteries of this underground cave world formed over hundreds of millions of years. It has enabled me to have a better understanding of the formation reasons of Zhijindong Cave, the types of geological relics, the kinds of stalactites and other knowledge, and also made me more aware of the preciousness of the resources of Zhijindong Cave."
