Although Aershan is called "mountain" but not mountain, it is a transliteration of Mongolian, meaning "hot hot spring". Of course, to my surprise, the unfrozen river, which is located in the Aershan Forest Park and overlooked by the tickets, is still flowing when the surrounding river freezes and slumbers in the cold. This is a miracle phenomenon. Because there is geothermal heat near the river section, the temperature of the river below -40 °C, the river will not only freeze, the water grows in the water, the river is steaming and hot, showing the sunset. Afterglow, radiant, bathed in soft light, the years are quiet. Tips
