Jianhe Hot Spring is a rare radon and sulfur hot spring in China, with a daily inflow of 1.8 million tons. It is rich in radon, sulfur, iron, potassium, calcium and other elements. Its physical and chemical indexes are similar to those of the famous French hot springs in Weixi, and it has the functions of disinfection, disease elimination and skin care. Frequent bathing can treat and prevent many difficult diseases. Since ancient times, it has enjoyed the reputation of "Miao Township Holy Water" and "Western Bathing Capital". 1989, it was developed into a modern spa. There is a Shule gym, which has a mandarin duck bath, sauna, beauty salon and four open-air baths, among which there is an open-air bath for local Miao compatriots, with a male pool above and a female pool below. Up to now, they still maintain the primitive habit of naked bathing. Naked bathing, in their view, is a natural phenomenon and there is no need to worry. As long as you don't peek on purpose, foreigners who occasionally appear by the bath won't care.
