Steam an outdoor sauna in Tengchong without changing clothes

♨️ As we all know, Tengchong is a mountainous area where volcanoes and geothermal coexist, so you will have a contrasting experience of being in an air-conditioned room in the mountains and in a hot outdoor area next to a geothermal hot spring. Outdoor sweating is also very good. ♨️ If you haven't been to other volcanic geothermal landscapes, it's still worth coming to Tengchong to see the Great Hot Pot. It mainly focuses on popular science, and you don't need to make special strategies. The scenic area has clear signs, so you won't go wrong by following them. There is a sulfur smell, but it's not very strong. My comparison object is the freshwater Xiaoyoukeng.
