At recent years some environmental protection and water conservation experts assert that hot spring made pollution and surface subsidence. In fact hot spring bathing and relaxation as low-carbon and high-efficiency health industry it should be supported and encouraged. China advocates energy saving and emission reduction, hot spring as geothermal energy is able to play a positive role. It will help us to reach our ambitious target for peak carbon dioxide emissions in 2030 and carbon neutrality in 2060.
