Introduction to the thermometer in the ice cave: At present, the Wannian Ice Cave has developed five floors, but due to conditions, only three floors are available for tourists to visit. On the first floor of the ice cave, visitors can see huge icicles formed by falling water into ice. On the second floor of the ice cave, visitors can visit a strange pool that is half water and half ice. The third floor of the ice cave has the most amazing sights, and the most fascinating one is the Gundam. The 30-meter jade waterfall condenses, and the huge ice waterfall pours down from the roof of the hall, which is extremely spectacular. The picture shows the thermometer inside the ice cave. Even in the hot summer, the temperature inside the ice cave remains around 0 degrees, which is refreshing and pleasant.
