Why do Millennium Ice Cave and Millennium Volcano coexist?

Wannian Ice Cave is located in Chunjingqi Township, 50 kilometers west of ningwu county, Xinzhou City, Shanxi Province, next to the tourist special line, with an altitude of 2,300 meters. In the east of Madigou Village, Qianshan Township, ningwu county, there is a world wonder-Wannian Ice Cave on the mountain at an altitude of 2,300 meters. It is unique in that, according to the climatic conditions outside the cave, it is impossible to form a cold environment, and icicles do not melt all year round in the cave, especially in summer, when green grass is blooming outside the cave and flowers are in full bloom, but the cave is cold and oppressive, and ice bamboo shoots stand tall.

The 10,000-year-old ice cave, which is 3 million years ago, is the largest ice cave discovered so far in China, and it is also a rare large ice cave discovered outside the frozen soil in the world. Wannian Ice Cave was rated as a national geological park. The scenery in the cave is big or small, exquisite, dazzling, graceful or magnificent, all of which are breathtaking, and it can be called a world of ice and snow.

The location of this ice cave is neither extremely cold north and south poles nor snow-capped mountains all year round, but in ningwu county, Shanxi Province, where the four seasons are very distinct, forming such an ice cave that does not melt all year round. No matter how hot it is outside, the ice cave is like this. So how did this ice cave form? So far, experts can't explain it.

What is even more curious is that there is a Millennium-immortal fire less than 200 meters away from the ice cave, which the locals call the Millennium volcano. Is the volcano formed by burning underground coal, or caused by lightning, or by crustal movement, or by spontaneous combustion after communicating with underground hot magma? The reasons for it were not known This ice and fire, which are similar in nature, wonderfully exist on the same mountain, which is a wonder of the world and a must in China.
