Yes, according to Tuniu. Lueyang Hot Spring is the first large-scale leisure business center integrating green leisure and hot spring health care in Shaanxi Province. It takes China's classical culture as its connotation and features natural hot springs. The hot spring water here comes from the underground 380 Ordovician limestone water system. The spring water is a sodium bicarbonate spring, which spews out of the ground and keeps the water temperature at 42 degrees Celsius all the year round. Therefore, Lueyang Hot Spring is a natural hot spring.
