Special thanks to the security in the scenic area. My father accidentally stumbled in the cave after crossing the glass trestle road. The security guard in front of me came to help and accompanied him all the way. He helped me find branches as crutches. He also helped my father go down the steps and up the steps to the platform exit. Thank you very much. I didn't want personal information, so I took two pictures. Thank you very much! Thank you also for the cooperation of other staff in the scenic area. At the same time, a small suggestion, after all, karst cave steps are relatively steep, if there are any emergency measures.
