Before entering the Crystal Palace, which was formed 10,000 years ago, you need to rent cotton clothes provided by the scenic spot to resist the cold in the cave. However, there are also handsome men and beautiful women wearing shorts and shorts to enter the ice cave to show a strong body. Tickets are 30 yuan, half discount for old-age tickets. The Crystal Palace (underground glacier) is more than 150 meters long and 23 meters deep. The hall on the front is 400 square meters. There are two branches of side holes. The maximum inside the hole is 5 meters. The top of the hole is sputum-like. The average temperature of the four seasons is minus 5 ℃. The colorful ice sculptures in the Crystal Palace Cave (ancient lady, city walls, Buddha statues, etc.) mask the real face of the underground ice river.
