Tornado Hell and Blood Pool Hell are together. Halfway to Tielun Hot Spring in the city, there is a bus pass for one day. Because it is far from the hot springs in Haiti Hell and other mountains, it needs transfer, so tourists are relatively few. Tornado Hell is characterized by eruption every 30 minutes. There is not much else in it. It is suggested that bus timetable should be taken into consideration to avoid wasting waiting for buses. Time.
