The Tengjiao Hot Spring Management District is rich in geothermal resources, with a geothermal area of ​​2.6 square kilometers and a geothermal water reserve of 100 million cubic meters. The outlet water temperature is as high as 98.6 °C, and the geothermal water contains six kinds of macro elements and seven kinds of trace elements which are beneficial to the human body such as strontium, fluorine, metasilicate and sodium sulfate. The single well draws a large amount of water, and the highest single well can raise more than 2,400 cubic meters.
