When hot geothermal water flows to reach the ground surface, it is called a hot spring. Based on the formation process, hot springs can be classified into natural hot springs and artificial hot springs. Artificial hot springs can be further divided into borehole hot springs and mining tunnel hot springs. According to the pressure of the groundwater, hot springs can be divided into non-pressurised and pressurised hot springs. Based on the pH of the water, hot springs can be categorised into acidic hot springs (pH <3), weakly acidic hot springs (pH 3–6), neutral hot springs (pH 6–7.5), alkaline hot springs (pH 7.5–8.5), and strongly alkaline hot springs (pH >8.5). Based on the content of chlorine ions, carbonate ions and sulphate ions, hot springs can be divided into chloride hot springs, bicarbonate hot springs and sulphate hot springs. According to the temperature (Chen Yanbing et al., from the perspective of medical therapy), hot springs can be divided into low-temperature hot...
