Go to Bailong Cave, if you are not driving by yourself, you can only take a taxi. The temperature inside is said to be kept at about minus 5 degrees all year round, which is also very magical. Before entering the cave, the scenic staff will recommend renting a coat for 10 yuan. But in fact, it didn't feel too cold, and because the length of the hole was not long, so the visit time was more than half an hour, and I personally felt that I didn't need to rent a coat.
